ABSTRACT

An experiment was conducted to evaluate 10 diverse parents and their 45 F1’s of bread wheat for yielding and physiological characters during season of Rabi 2014-15. Analyses of variance in 55 (45 F1’s with their 10 parents) bread wheat genotypes for eighteen characters were showed highly significant differences indicate the presence of extensive amount of genetic variability. On the basis of mean performance, high yield per plant was observed for DBW 14 x K0424 followed by K 9162 x K 9423. Cross K 0607 x K 0911 exhibited maximum protein content in grain. The estimate of PCV and GCV were high for canopy temperature depression (0C) and for grain yield per plant, respectively. The high heritability was observed for protein content whereas grain yield per plant showed high genetic advance. Accordingly results, effective genotypes based on either mean performance and high heritability coupled with high genetic advance for interesting traits can be used further improvement of yield and its related traits through ideal breeding scheme.

Key words: Genetic variability, heritability and wheat hybrid
