Genetic Analysis of Yield Traits and Phenotypic Screening for Fusarium Wilt in Lentil at Kymore Plateau, Madhya Pradesh, India

To evaluate genetic variability and the correlation between yield-attributing traits and seed yield, 92 genotypes—including two checks—were analysed for respective traits and seed yield. The analysis of variance revealed significant differences between the genotypes for each attribute that was studied. High heritability and high genetic advance as a percentage of mean were demonstrated by traits like the number of effective nodes per plant, the number of pod clusters per plant, the number of seeds per pod, the number of primary branches per plant, the number of seeds per plant, the hundred seed weight, the biological yield per plant, the harvest index, and the seed yield per plant. Characters including the number of seeds per plant, the number of pods per plant, the number of seeds per pod, the biological yield of the plant, and the harvest index have shown a positive and statistically significant correlation with seed yield per plant. A path coefficient analysis revealed that seed yield per plant was favourably influenced by the number of seeds per plant, harvest index, and biological yield per plant. In addition to genetic analysis the genotypes were evaluated for Fusarium wilt response under natural field conditions to identify genotypes with potential disease tolerance.
