Character association and path coefficient analysis in coriander under normal and limited moisture conditions

Abstract

A study was undertaken to study the correlation among yield contributing traits of coriander under two moisture regimns. The estimates of genotypic correlation coefficient were higher than their respective phenotypic correlation coefficients for most of the characters indicating strong genetic association between characters. The seed yield per plant showed positive and significant correlation with branches per plant, umbels per plant, seeds per umbel and test weight in normal environment, whereas with branches per plant and umbels per plant, under limited moisture environment. The highest direct and positive effect towards seed yield per plant was due to branches per plant followed by test weight, days to maturity, umbels per plants and seeds per umbel in a normal environment, whereas, in limited moisture environment, umbels per plant had the highest direct and positive effect followed by days to maturity, branches per plant, test weight and plant height. Thus branches per plant and umbels per plant had a high positive correlation as well as a high direct and positive effect towards seed yield per plant under both the environment and suggested that the aforesaid characters may be considered as important in breeding programmes aiming to coriander yield improvement.
