Abstract

The current research was carried-out to evaluate 19 exotic bread wheat genotypes for yield and its associated characters along with check variety (Imdad-05). The analysis of variance, mean performance and heritability (broad sense) were analyzed. Mean squares of the genotypes were differed significantly at P ≤0.01 for all the traits except spikelets spike-1 , registering the significant genetic variability among the genotypes for further evaluation. With regards to mean performance, the Mex-line-19 not only showed better performance for various traits among the Mexican lines but also surpassed check variety (Imdad-05) for yield and its associated traits. It is suggested that the Mex-line-19 proved outstanding exotic wheat accession which can rather be released as pure line variety, after testing its stability in different conditions. Moreover, this superior line can also be used as one of the parents in hybridization programs in order to introduce promising characters in bread wheat cultivars. High and moderate heritability estimates were found for most of the studied traits, indicated that the variation observed was mainly under genetic control and was less affected by environment, referring the influence of additive gene action for these traits. Thus, the improvement of these traits can be made through direct phenotypic selection.
