Abstract:

The changing climate adversely affect the morphological characters of plant which, ultimate effect the identification of off types in seed production programme. This also leads to effect the genetic purity in seed production programme. To overcome this problem selection of progeny and its breeding depend upon the genetic variability in population. Fourteen varieties of wheat and their forty crosses were evaluated in randomized block design (RBD) with three replications for yield components and physiological traits during rabi 2015-16, to find out genetic variability, heritability and genetic advance percent of mean. Significant genetic differences were observed for all the quantitative characters studied, indicating considerable amount of variation among genotypes. Moderate genotypic and phenotypic coefficient of variation exhibited by grain yield per plant,  biological yield per plant, ear weight, number of ears per plant, peduncle length and sedimentation value while, number of tillers per plant and harvest index showed moderate PCV but low GCV.  All of the traits expressed high heritability. However, biological yield per plant and sedimentation value showed high and moderate genetic advance, respectively which, indicates that the heritability is most likely due to additive gene effect and selection may be effective for these traits. It is also observed that the performance of these characters is not under influence of environment. However, other characters might be effected by the change in climatic condition. Thus, in seed production programme at the time of rouging these characters must be considered to maintain the genetic purity of seed.
