Genetic parameters studies for yield attributes in moringa genotypes (moringa oleifera lam.)

Moringa (Moringa oleifera Lam.) is given great importance as a vegetable. The leaves, pods and flowers of this tree are used exclusively as nutritious food. The present trend in crop improvement programmes is the development of high yielding cultivars to boost the productivity and profitability. This experiment was conducted with 20 genotypes of drumstick in the randomized block design (RBD) with three replications during 2018-19 at Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon (C.G.).Genetic parameters studies for variability, correlation and path coefficients analysis of twenty genotypes of Moringa for twelve yield attributes revealed that the characters leaf length, number of pod per plant, plant height, pod girth, number of branches per plant and number of seeds per pod showed high GCV and high heritability along with high genetic advance and these characters are controlled by additive gene. The study of path analysis indicated that the direct selection of number of leaves per rachis, number of branches per plant, number of pods per plant, number of flower per inflorescence, stem girth, leaf length and plant height could be used as selection criteria for improvement. Association analysis revealed that selection criteria based on number of branches per plant, length of pod, leaf length, pod girth and number of pod per plant, pod weight and plant height can provide better result for improvement of pod yield in Moringa.
