(Soc Field Crop Sci, 2020) Ahmed, Asgar; Hossain, Akbar; Amiruzzaman, Md; Alam, Md Ashraful; Farooq, Muhammad; El Sabagh, Ayman; Kizilgeci, Ferhat
In Bangladesh, maize stands second place after rice; since it faces diverse natural calamities during its highest growing season (rabi/winter), particularly strong storm during the reproductive stage. Sometimes in some regions, this crop is completely damaged by natural disasters. Considering the burning issue, thirteen hybrids, including 10 previously selected short stature hybrids were evaluated against three local and standard checks: 'BHM-9', '981' and 'Sunshine' in two consecutive years in seven locations of Bangladesh. Combined analysis over locations and seasons instigated that genotypes 'Sunshine', '981' and 'G10' were the top-high yielders, while genotypes 'G1', 'G2', 'BHM-9' and 'Sunshine' were found the most stable. On the other hand, five genotypes such as 'G3', 'G4', 'G6', 'G8' and 'G9' had the below-average mean yield and the genotypes 'G6' and 'G9' were the most unstable. Among the seven environments, Jamalpur, Joydebpur and Dinajpur were most discriminating and Ishwardi was the least discriminating; whereas Joydebpur was more representative and Borishal was the least representative of other test environments. In the case of plant and ear height, most of the genotypes showed a lower value than all the checks, which was desirable. But among the top three high yielders, local cross-genotype, the 'G10' had the lowest and more stable value for both plant height and ear height. Therefore, considering the plant and ear height, grain yield, and yield stability, the genotype 'G10' has been recommended for release as commercial variety and has been released as new maize variety in Bangladesh with the local name of 'BARI Hybrid Maize-16' (BHM-16).

Wheat cultivars generally show significant differences for grain yield, quality and physiological parameters under different environmental conditions. Thus it is crucial to assess the performance of bread wheat genotypes collected from different origins for domestication for a specific ecologic conditions and also to develop high yield as well as stress tolerant cultivars. In the context, the study was carried out under the ecological condition of Diyarbakır in Turkey during 2014-2015 growing season. In the present research, three Turkish origin bread wheat cultivars such as 'Pehlivan', 'Ceyhan 99' and 'Seri 2013' and eleven bread wheat of Australian origin such as 'LPB 08-1799', 'Eagle Rock', 'Magenta', 'Emu Rock', 'Wyalkatchem', 'Young', 'Calingiri', 'Yitpi', 'Corack', 'Envoy' and 'Mace' were used as experimental plant material. Data on grain yield, grain hardness, plant height, test weight, thousand kernel weight, wet gluten, protein content, zeleny sedimentation, starch content, normalized differences vegetative index, SPAD, leaf area index and canopy temperature were investigated in the study. After evaluation, it was found that all recorded traits of fourteen wheat bread cultivars were changed according to cultivars under the ecological conditions of Diyarbakir-Turkey. However, genotypes which were Australian origin performed the best than Turkish origin. Among the genotypes, the maximum values for grain yield, quality and physiological parameters were recorded for cultivar, 'Mace' (for grain yield) and 'Young' (for quality traits). Therefore, cultivars which were Australian origin can be grown and also may be used in the breeding programs to develop wheat cultivars to cultivate under the Diyarbakir ecological conditions of Turkey.

(2021) Hossain, Akbar; Kızılgeçi, Ferhat; Milon, M S H; Teixeria da Silva, Jaime A; Gaydon, Donald S; 16.02. Department of Seed Production / Tohumculuk Teknolojisi Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
To assess the heat stress tolerance of recently released wheat varieties, six of these varieties (Shatabdi, BARI Gom 26, BARI Gom 27, BARI Gom 28, BARI Gom 29 and BARI Gom 30) were evaluated at two sowing conditions (optimum sowing on November 15 and extremely late sowing under heat stress on January 15). All treatments were arranged in a randomized complete block design with a split–plot arrangement and repeated three times. Two sowing dates were arranged in the main plots and six wheat varieties were assigned to sub–plots. The varieties that are suitable to grow under late sowing were recognized based on phenological data such as date of booting, heading, anthesis and physiological maturity, growth data such as plant population, number of tillers m–2, plant height, leaf area index, total biomass at the booting stage and plant height at harvest. Besides phenological and growth data, yield and yield attributes such as spikes m–2, spike length (cm), spikelets spike–1, grains spike–1, 1000–grain weight (g), grain yield (GY, kg ha–1), straw yield (kg ha–1), biological yield (kg ha–1) and harvest index were also recorded. Stress–related parameters such as yield stability index, stress tolerance index, stress intensity and heat susceptibility index were also estimated for final confirmation of heat tolerance of varieties. In optimum sowing conditions, phenology, growth, yield and yield components were significantly higher than in late sowing under heat stress. Among these wheat varieties, significantly (p < 0.01) highest GY was obtained from Shatabdi (5,096 kg ha–1) and lowest from BARI Gom 27 (3,955.33 kg ha–1) when sown under optimum conditions. When sown at late, BARI Gom 30 was found to be heat tolerant and produced maximum GY (1,834.33 kg ha–1), whereas BARI Gom 27 was highly sensitive to heat and produced the lowest GY (1,353 kg ha–1). Under both sowing conditions (optimum and late sowing), significantly maximum GY and biological yield were recorded in variety Shatabdi (3,419 kg ha–1), and the lowest was observed in BARI Gom 27 (2,654 kg ha–1). By evaluating heat tolerance indices, BARI Gom 30, followed by BARI Gom 29, BARI Gom 26 and Shatabdi were found to be tolerant to heat stress, whereas BARI Gom 27 and BARI Gom 28 were susceptible to late–sowing heat stress condition. Therefore, except for BARI Gom 27 and BARI Gom 28, the remaining four varieties (Shatabdi, BARI Gom 26, BARI Gom 29 and BARI Gom 30) are recommended for sown late heat stress condition and could also be used in a future breeding program to develop heat–tolerant varieties

Turgor maintenance through osmotic adjustment can play a vital role in plant tolerance to drought and salinity. As per the evidence of the previous study, chemical polyethylene glycol (PEG) can create physiological drought under both salinity and water deficit conditions. Therefore, PEG is used for forcefully create osmotic stress to find out drought and salinity resistant crop cultivars at the early stage. Considering the essential role of PEG, the current observation was undertaken for understanding the effects of drought and salinity stress on several bread wheat genotypes at early developmental stage particularly during the seedling stage. Five bread wheat genotypes including four varieties such as 'Tekirdag', 'Ceyhan 99', 'Dine', 'Empire Plus' and a line 'DZ17-1' were used as seed material. To find out the genotypes which are tolerant to drought and salinity, all wheat genotypes were evaluated in four different concentration of NaCI for salinity stress (i.e., 0, 4, 8 and 12 dS/m) and four different concentration of PEG 6000 (i.e., 0, -0.2, -0.4, -0.6 MPa) for drought stress. All treatments were organised in a completely randomized design (CRD) and repeated three times. After observation, it is revealed that bread wheat cultivars 'Dine' and 'Ceyhan 99' were found tolerant of both drought and salinity stress at the seedling stage. The study also noticed that understanding of seedlings growth such as mean germination time (MGT), coleoptile length, seedling height, root length and relative water content (RWC) allow the selection of genotypes tolerance to drought and salinity. The information from the study will be helpful for examination of wheat genotypes which are suitable to cultivate under osmotic stress of both drought and salinity stress condition.

Phenology, Growth and Yield Are Strongly Influenced by Heat Stress in Late Sown Mustard (Brassica Spp.) Varieties
(Pakistan Botanical Soc, 2020) Bazzaz, Md Mahfuz; Hossain, Akbar; Farooq, Muhammad; Alharby, Hesham; Bamagoos, Atif; Nuruzzaman, Md; El Sabagh, Ayman
In rice-based cropping system of northern Bangladesh, mustard planting is delayed due to late harvest of monsoon rice (Transplanted Aman rice; T. Aman rice). The late sown mustard is often exposed to high-temperature stress during the reproductive stage, which causes a significant decrease in seed yield. Most of the farmers plant a low yielding local mustard variety 'Tori-7', which is sensitive to high-temperature stress. The Oil Seeds Research Centre of Bangladesh Agricultural Research Institute has recently released short duration and high-yielding mustard varieties for the rice-based cropping system of northern Bangladesh to tackle this issue. However, the performance of these varieties in the target cropping system under late sown conditions (together with exposure to heat stress) has not been evaluated yet. Therefore, this two-year field experiment was conducted to assess the performance of newly released mustard varieties 'BARI Sarisha-14' and `BARI Sarisha-15' in comparison with the local check variety 'Tori-7' sown at five planting dates (viz. October 21, November 1, November 10, November 20, and November 30). The delay in sowing shortened time (days) to flowering and maturity, regardless of the variety. Similarly, plant height, branches/plant and total dry matter accumulation of the tested varieties were also reduced upon delay in planting. The greatest seed yield was observed in varieties `BARI Sarisha-15' and `BARI Sarisha-14' when sown on October 21. These two varieties produced fair seed yield when sown at November 20. However, the local variety 'Tori7' yielded the least across all the planting dates. Therefore, the varieties `BARI Sarisha-14' and `BARI Sarisha-15' may be planted in the rice-based cropping system of northern Bangladesh after harvest of T. Aman rice to get maximum seed yield.

Malnutrition is one of the major problems in the poor people of Bangladesh. There are some reports that additional nitrogen (over than recommended does) application to wheat plants result in more protein content in wheat grain. To justify these phenomena; the experiment was conducted in consecutive two years (2015-16 and 2016-17) at two locations (Gazipur and Dinajpur) during rabi season (November to March each year). There were used six nitrogen (N) treatments, such as 0, 100, 125, T-3; 150, 175 and 200 kg N hat. In the study, wheat cultivated at Dinajpur location exhibited more spikes m(-2), spike length, spikelets spike(-1), grains spike(-1), 1000-grain weight and higher grain yield in both years than Gazipur location. Considering combined N levels over the locations, the highest grain protein (14 %) as well as grain yield (5.00 t ha(-1)) was estimated when 200 kg N ha(-1) was applied. In economics point of view, 200 kg N ha(-1) application also gave the maximum (BCR, 1.21) followed by 175 kg N ha(-1) (1.20) and 150 kg N ha(-1) 1.20). Whereas, the maximum MBCR was found in 100 kg N ha(-1) (15.63). Therefore, to minimize malnutrition severity among the children as well as adult people in the developing countries like Bangladesh, 175 or 200 kg N ha(-1) may he applied in wheat to increase percentage protein in wheat grain.
