Abstract:
The development of high-yielding, genetically diverse and climate resilient wheat varieties is critical for ensuring global food security under changing climatic conditions. This study aimed to evaluate locally developed wheat lines for agronomic traits, biochemical profile and to screen the wheat genotypes for important characters through marker assisted selection. The agro-morphological assessment included plant height, days to heading, days to maturity, grain yield per plot, grain yield per hectare, thousand grain weight and the evaluation of seed quality for different minerals. The lowest days to maturity were recorded for the Genotypes 1 and 11 (172 days), while the lowest days to heading were observed for the Genotype 16 (126 days). The highest grain yield per plot was recorded for the Genotype 24 (1301 g). Genotype 21 had a maximum yield of8185 kg/ha. Maximum thousand grain weight was recorded for the Genotype 18which was 45 g. Furthermore, the seed quality analysis revealed that Genotype16 had maximum zinc concentration of 39.51 ppm. The Genotype 23 had maximum concentration of iron (61.57 ppm) and maximum concentration of calcium (718 ppm). Maximum manganese concentration was noted for the Genotype 24 which was 92.3 ppm. Genotype 4 revealed maximum concentration of copper which was 7.92 ppm. Maximum magnesium concentration was observed in Genotype 22 which was 1638 ppm. Genetic analysis revealed that most of the genotypes had WMC9, WMC147, WMC596and Ppd-D1 markers present and these markers were linked to drought tolerance and photoperiod response. UPGMA cluster analysis grouped the twenty-five genotypes into two major clusters, genotypes in group A had high yield, while genotypes grouped in B2 had high magnesium mineral. Correlation analysis showed that plant height had positive correlation with copper whereas thousand grain weight had correlation with iron and negative correlation was observed between thousand grain weight and Ppd-D1. These findings can provide important revelations into the genetic and agro-morphological profiles of the wheat genotypes which can be useful for selecting the best genotype to be released as variety.
