 ABSTRACT

One hundred bread wheat (Triticum aestivum L.) were evaluated for genetic variability and yield performance under rainfed condition in two replication using alpha-lattice design. Substantial variations were reported among genotypes with ANOVA for all the fourteen studied traits. Low to moderate range of GCV (1.7-17.1%) and low to high PCV (2.3-23.4%), GAM (3.5-32.6%) and heritability (42.9-79.2%) were reported. At genotypic level GY showed positive and highly significant correlation with DTH, DTA, DTM, NOT, SL, BM, HI, TKW and TNG at genotypic level and with DTM, BM, HI, TKW and TNG at phenotypic level. TKW and TNG showed highest positive and direct effect on GY in path analysis. Genotypes HI1531, HI1581 and C306 were showed highest yield.

Keywords: Wheat, Rainfed, Genetic variability, Correlation, Path analysis.
