Estimates of genetic diversity for morphological and yield contributing traits in coriander genotypes

Abstract

Genetic variability, divergence, correlation and path coefficient were estimated in twenty eight genotypes of coriander during Rabi 2014-15 and 2015-16. Highest genetic advance was observed for seed yield per plot followed by plant height. Highest heritability was estimated for number of primary branches followed by plant height. Genotypes were grouped into 12 clusters. Minimum inter-cluster D2 value (2.57) was estimated between clusters II and V whereas, maximum inter-cluster D2 value (9.54) was estimated between clusters III and VI. The seed yield was found significantly and positively correlated with plant height, test weight and seed yield per plot. Path coefficient analysis indicated the highest positive direct effect of number of umbels per plant on 5 plants seed yield followed by number of primary branches and test weight.
