Abstract
Lentil (Lens Culinaris) is one of the most important sources of protein worldwide and most widely consumed. This plant has high nutritional value among legumes. The present study was conducted to estimate broad-seanse heritability and to perform clustering of lentil genotypes using multivariate statistical approaches. Genotypes were evaluated in a randomized complete block design with three replications at Sarab-Changai Research Station, Lorestan Agricultural and Natural Resources Research and Education Centre, Khorramabad, Iran. Traits were recorded for each genotype and raw data were analyzed using Statistical experimental design model and multivariate statistical methods. Analysis of variance indicated significant differences between genotypes in most of traits. The highest heritability estimates were observed for total dry matter per plant, number of two-seeded pods, and number of seeds per pod. Based on the results of most multivariate analyses, genotype G5 was identified as the superior genotype, whereas genotype G6 was consistently classified as the weakest. The Superior Genotype Index (SIIG) was used for the final ranking of the 15 lentil genotypes. Overall, the results indicate that genotype G5, which showed high heritability for key yield-related traits, is the most promising genotype and has strong potential for use in future breeding and subsequent research programs.
