Genetic variability studies for foliage yield components in coriander (Coriandrum sativum L.) germplasm

Abstract

The present investigation was undertaken to assess the variability, heritability and genetic advance in Coriander germplasm maintained at Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). twenty eight genotypes of coriander were evaluated for 22 qualitative and quantitative characters to study the genetic variability and association of the traints. The analysis of variance revealed considerable genetic variability in the evaluated genotypes. The GCV and PCV estimates were high for leaf stem ratio, dry stem weight, root weight, fresh stem weight and foliage yield kg plot-1 indicating better scope for improvement through simple selection. These characters also depicted high estimates for heritability and genetic gain indicating additive type of gene action. Foliage yield kg plot-1 showed positive and significant association with plant height, number of branches plant-1, stem base diameter, number of leaves plant-1 and leaf length. Among the genotypes tested for performance studies, COR-07 and COR-10 recorded the highest foliage yield potential under Chhattisgarh.
