Abstract:
The present investigation is carried out with 40 bread wheat (Triticum aestivum L.) genotypes in the experimental area of research farms, genetic and plant breeding section of Lovely Professional University, Jalandhar, Punjab during the rabi season of 2022-23 to assess the genetic parameters viz, genotypic, and phenotypic variance, genotypic and phenotypic coefficient of variance, heritability, and genetic advance as percent of mean. Fifteen different traits were recorded and recorded and assessed using Randomized Block Design. The analysis of variance unveiled notable variations among the assessed genotypes for each parameter considered. Environmental influence on the expression of the traits was minimal, as indicated by slight disparities between the genotypic and phenotypic coefficients of variation. Traits such as spike length, spike density, spike weight, and number of spikelets per spike displayed both a high degree of heritability and a substantial genetic advance as a percentage of the mean. This indicates that implementing straightforward selection methods would be successful in driving genetic enhancements for these traits.
