Genetic divergence and cluster analysis in coriander germplasm (Coriandrum sativum L.) in high hills of Garhwal Himalayas

Twenty four genotypes of coriander were evaluated in Kharif season for different horticultural traits viz., days to 50% flowering, days to first umbel unfolding, Maturity duration, plant height, primary branches per plant, secondary branches per plant, test weight, fruits per umbel, fruits per umbellate, seed yield per plot and seed yield per plant etc. Cluster analysis based on Ward’s minimum variance procedure distributed the into 5 clusters indicating their broad genetic base of which Maximum numbers of genotypes were accommodated in the cluster-IV (9) followed by cluster-I (4) cluster-II (4) and cluster-V (4). The intra cluster distance was found maximum in cluster III and minimum in cluster II. Whereas, highest inter cluster distance was recorded between cluster III and IV and lowest was observed between cluster IV and V. While there genetic diversities were classified on the basis of D2 analysis these genotypes were grouped into five divergent clusters and hybridization between cluster III and IV is expected to give maximum heterotic cross combinations in future breeding programs. | Genetic divergence and cluster analysis in coriander germplasm (Coriandrum sativum L.) in high hills of Garhwal Himalayas
