Analysis of Promising Barley (Hordeum Vulgare L.) Lines Performance by AMMI and GGE Biplot in Multiple Traits and Environment
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Tekdal, S.; Dogan, S.; Kendal, E.; Karaman, M.
The development of stable and adaptable new cultivars are based only on positive results obtained from the interaction between the genotype and the environment. Therefore, the study aimed to test the stability and general adaptability of promising barley lines in terms of grain yield and traits in multi -environments. For this purpose, twelve barley genotypes were used in the study. The trials were carried out with four replications in a random design at seven environments in years 2012-13 and 2013-14. The superior and stable genotypes were identified with GGE biplot and AMMI (Additive main effects and multiplicative interaction) models. The AMMI analysis showed that the major treatment sum of squares was affected by environments (80.6%), GE (14.0%) and genotypes (5.4%), respectively. On the other hand, the first two principal component axes (PCA 1 and PCA 2) contributed to the complete interaction with 88.1%, whereas, PCA 3 and PCA 4 axes only with 12.0%. The GGE biplot indicated that G4 is adaptable for all environments, while Altikat, G2 and G3 showed specific adaptation to El, E3 and E5, G6, G7 and G8 to E6, respectively. According to both techniques, G2, G3, G6, G7, G8 and Altikat were the best genotypes with high yield, whereas G4 was the best with high yield, and stable and general adaptation. The results of biplot indicated that G4 (ARUPO /K8755//MORA/3/CERISE/SHYRIHALEL I/4/CANELA/5/HART-BAR) was recommended for release and it was released as HEVSEL in 2017. On the other hand; G7 and G6 were protected as genetic material to use as parent in breeding programs for yield stability and quality respectively.

Comparison of Bread Wheat (triticum Aestivum L.) Lines With Registered Cultivars in Terms of Yield and Quality Characteristics
(Aloki Applied Ecological Research and Forensic inst Ltd, 2020) Karaman, M.; Aktas, H.
The study was carried out under rainfall conditions during the 2011-2012 and 2012-2013 growing seasons in Diyarbakir province of Turkey. The experiment had designed as a randomized block design with 3 replications. The aim of the study was to determine the lines that were superior in terms of yield and quality to the varieties. The experimental material consisted of 20 bread wheat lines and 5 standard varieties. According to the results of variance analysis; significant differences were observed between genotypes in all features at 1%. Grain yield (GY) had a significant positive relationship with test weight (TW), and a significant negative relationship with wet gluten (WG). Also, grain hardness (GH) (PSI: Particle size index) had significant negative relationship with TW, and a significant positive relationship with plant height (PH) and heading time (HT). 4 lines in grain yield, 3 lines in test weight, 1 line in protein content, 4 lines in zeleny sedimentation and 1 line in wet gluten showed superior performance than all standards It is concluded that the G19 and G24 lines may be candidates for registration.
