Abstract:
The overall objective was to study the extent of genetic variation and association among grain yield and micronutrient (Zn & Fe) traits. Fifty-two germplasm of bread wheat were tested in Randomized complete block design. There was significant variability among wheat genotypes for yield as well as associated morphological and micronutrient traits which can be utilized in wheat breeding programs. The phenotypic coefficients of variation values were higher than genotypic coefficients of variation values. High PCV and GCV were recorded for number of tillers per plant, iron, grain yield per plant, flag leaf area. High heritability values were observed for iron, zinc, 1000 grain weight, grain yield per plant, plant height and days to 50 percent flowering. Among the traits iron, grain yield per plant, zinc and 1000 grain weight had high values of genetic advance as percent of mean (GAM). However, Grain yield showed positive and significant correlation with plant height, 1000 grain weight at phenotypic level. The lines with higher Zn and Fe content along trait could be dynamic components of functional food and improved food nutritional quality. The data generated in study provide useful resources for its development in wheat breeding programme.
