Studies on variability of some morphological characters in coriander (Coriandrum sativum L.)

Abstract

Analysis of variability carried out for 17 characters in 20 genotypes of Coriander (Coriandrum sativum L.) revealed highly significant differences among genotypes for all the characters studied. High genotypic and phenotypic variation was observed for character like plant height secondary branches and plant spread. High genotypic and phenotypic co-efficient of variation was observed for seed yield per plant, essential oil, seed yield per ha and plant spread. High heritability was observed for the characters like plant height at harvest, days to first flowering, seed yield per hectare, maturity, dry matter production, seed yield per plot, harvest index, essential oil content, days to 50 percent flowering and test weight. High genetic advance was observed for plant spread, seed yield per plot and plant height at harvest. High genetic advance as percent of mean was observed for number of primary branches at harvest, plant spread, harvest index, essential oil and seed yield per plant and per hectare. High genetic advance over percent of mean coupled with high heritability was observed for the characters like plant height at harvest, plant spread, harvest index, essential oil, dry matter, number of umbellets per umbel, seed yield per plant and seed yield per hectare. Therefore, greater emphasis should be given on these characters while selecting for higher yield and related traits.
