 ABSTRACT

The present investigation was undertaken to study the genetic variability, correlation and path coefficient analysis, for grain yield and its attributes with a set of 50 genotypes of bread wheat (Triticum aestivum L.) at Instructional Farm, Department of Agronomy, Junagadh Agricultural University, Junagadh during Rabi 2018-19 in randomized block design with three replications. The characters studied were days to 50% flowering, grain filling period, days to maturity, plant height, number of productive tillers per plant, ear length, number of grains per main spike, grain weight per main spike, grain yield per plant, biological yield per plant, harvest index and 1000-grain weight. The analysis of variance revealed highly significant differences among the mean square due to genotypes for all the characters studied. High genotypic and phenotypic coefficient of variation were observed for 1000-grain weight followed by grain weight per main spike. High heritability coupled with high to moderate genetic advance expressed as per cent of mean were observed for 1000-grain weight, grain weight per main spike, days to 50% flowering, number of grains per main spike, plant height. Grain yield per plant had significant and positive correlation with ear length, grain weight per main spike, harvest index, number of grains per main spike and plant height at both the genotypic and phenotypic levels. The phenotypic path coefficient analysis revealed that the harvest index, biological yield per plant, grain weight per main spike exhibited high and positive direct effects on grain yield per plant. On the basis of all the above studies, it can be concluded that due weightage should be given to 1000-grain weight, days to 50% flowering, ear length grain weight per main spike, number of grains per main spike, harvest index and plant height while imposing selection for genetic improvement in bread wheat.

Keywords: Variability, Heritability, Genetic advance, Correlation, Path analysis, Bread wheat.
