 ABSTRACT

Genetic variability and correlation studies were carried out using line x tester analysis for grain yield, yield related and quality traits in 15 parental genotypes (12 lines and 3 testers) and 36 F1 hybrids in a line x tester scheme. This material along with 2 commercial check varieties was evaluated using Randomized Block Design in 3 replications. The purpose of the study was to determine the extent of genetic variability for various characters and estimation of genotypic and phenotypic correlation coefficients between these traits. Analysis of variance revealed highly significant genetic differences among the genotypes for all the characters.Days to heading, protein content and sedimentation value showed negative correlation with grain yield per meter. Number of grains per spike was significantly and positively correlated with grain yield per running meter.

Key words: Bread wheat, yield, Quality traits, Genetic variation, Correlation coefficient.
