Correlation and Path Coefficient Analysis Study among Seed Yield and Oil Content in Ethiopian Coriander (Coriandrum sativum L.) Genotypes
Geremew Awas, Firew Mekbib and Amsalu Ayana

Abstract:
Eighty one Ethiopian coriander genotypes were evaluated in 9x9 simple lattice design to study correlation and path coefficient analysis for seed yield and oil content at Adami Tulu Agricultural Research Center during 2011/12 cropping season. Data was collected on 21 seed yield and yield related characters. Seed yield per plant was highly and positively correlated with umbel number per plant, biomass yield per plant and number of seeds per plant, while it was negatively correlated with days to start of flowering, days to 50% flowering and plant height at flowering at both genotypic and phenotypic level. Fatty oil content was highly and positively correlated with thousand seed weight, number of primary branch and harvest index per plant, while it is negatively correlated with days to 50% flowering, days to start of flowering and plant height at flowering at both genotypic and phenotypic levels. The path coefficient analysis of seed yield per plant revealed that biomass yield per plant, harvest index per plant and number of seeds per plant were the major positive direct effect contributor, while days to start of flowering, number of primary branch and plant height at flowering exerts high negative direct effect at both genotypic and phenotypic levels. High positive indirect effect were exerted by fatty oil content via harvest index, days to maturity via plant height at flowering and thousand seed weight via days to start of flowering at both phenotypic and genotypic levels. Similarly negative indirect effect were exerted by harvest index per plant via biomass yield per plant, plant height at flowering via thousand seed weight and days to maturity via thousand seed weight. The genotypic and phenotypic path coefficient analysis of fatty oil content showed that, seed yield per plant, thousand seed weight and number of primary branches are the major positive direct effect contributors while, harvest index per plant, plant height at flowering, umbel number per plant and days to 50% flowering exerts high negative direct effect on fatty oil content.
