Assessment of variety releasing performance from winter wheat germplasm at Diyarbakir condition

Abstract

Spring wheat genotypes have been successfully grown with global climate change in the mate dominates. In the cold winter season, however, yield losses in spring wheat genotypes are occasionally reported. In order to solve this problem, wheat genotypes that are resistant to winter damage and suited for spring growing type must be identified. The focus of this research was to determine how winter ratio, plant height, spike length, spikelet number, spike grain number and grain weight variability of 50 wheat genotypes were ranged between 157.2- 494.7 kg da-1, 9.33-14.57 %, 82.7-88.9 %, 56-102.3 cm, 6.3-12.5 cm, 13.8-23.6, 30.6-64.4 and 28.2-56.6 g, respectively. The findings suggest that there is a large genetic variation in the traits studied, and that suitable wheat genotypes can be discovered either directly or through breeding research. According to the cluster analysis, clustering the genotypes by cutting the dendogram into 6 groups will improve genotype selection for hybridization and allow for more genotypic variation to be benefited from. The significant association between protein content and grain yield suggests that high-yielding and high-quality cultivars can be identified. The parameters controlling the grain number have a favorable impact on grain yield, while grain weight has a negative impact, according to the component analyses. The findings suggest that winter wheat trial sets can be used to identify genotypes suitable for spring type conditions.
