Abstract:
The current research was carried out at Project Coordinating Unit (Sesame and Niger) Research Farm, JNKVV, Jabalpur (M.P.) during kharif 2021 for the assessment of genetic diversity among 84 genotypes of niger using principal component analysis. In this investigation, Principal component 1 had the contribution from the characters viz., number of seeds per capitulum, harvest index and seed yield per plant contributing 37.46% to the total variability. Days to flower initiation and days to 50% flowering contributed 17.32% to the total variability in principal component 2. Plant height had contributed 11.35% to the total variability in principal component 3. Days to maturity and diameter of capitula contributed 8.33% to the total variability in principal component 4. The cumulative variance of 74.46% of total variability was observed among 12 characters was explained by first four axes. The result of principal component analysis revealed that Goudaguda, AJSR-45, AJSR-35, IC-210956, AJSR-24, AJSR-29, AJSR-25, AJSR-49, AJSR-43, IC-210948, AJSR-28, IC-210947, JNS-30 (C), IC-210925, AJSR-36 and AJSR-61 were potential lines. Therefore, these lines should be utilized for further breeding program to achieve trait specific desirable varieties of niger with wider adaptivity.
