Genetic Variability and Association of Characters in Wheat (Triticum aestivum L.)
Bangshi Dhari Kotal, Arpita Das and B.K. Choudhury

Abstract:
In the present investigation, an attempt has been made to evaluate the genetic variability and correlation of different contributing characters associated with grain yield per plant in wheat. Fourteen genotypes were grown in Randomized Block Design with three replications and evaluated for ten characters. Analysis of variance was done from the mean data obtained in each character and correlation and path coefficient analysis were carried out. Highly significant differences and adequate genetic variability were observed among the genotypes for all the ten selected characters. In this context, it was found that numbers of effective tillers per plant and grain yield per plant were characterized by high GCV, high heritability and high genetic advance and would be effective for selection. Correlation studies and path coefficient analysis revealed the importance of number of effective tillers per plant, number of spiklet per panicle, number of grains per panicle and harvest index for improving grain yield per plant as they had positive direct effects on yield and these traits were also significantly and positively correlated with grain yield per plant. So for increasing grain yield per plant a wheat genotype should have more number of effective tillers per plant, more number of spikelet per panicle, more number of grains per panicle and high harvest index value because these characters were positively associated with grain yield and resemble high estimates of heritability along with high genetic advance. In this regard the importance of large panicle length and more 1000 grain weight could not be under mined for yield improvement.
