Abstract

Genetic diversity is the basis for improvement of crop plants. The study of morphological traits is considered an effective tool for the preliminary assessment of genetic diversity together with the crop improvement programme. The diversity of plant genetic resources provides an opportunity to plant breeders for the advancement of novel and improved cultivars with desirable traits. The contemporary investigation was initiated at the research farm of SKUAST-Jammu, during wet season 2020 for the characterization of BC3F5 population comprising the advanced breeding lines of basmati rice, developed from diverse parents. Twenty nine advanced breeding genotypes of basmati rice were laid out in a randomized block design (RBD) along with three replications. The experimentation was accomplished by applying Tukey’s test. The analysis of variance (ANOVA) exhibited statistically significant differences (p<0.01), indicating the presence of genetic variability amongst the population, which can be
