Variability, heritability and genetic advance in chrysanthemum (Chrysanthemum morifolium Ramat.) under ecological conditions of sub-humid zone of Rajasthan

Studies on genetic variability, heritability and genetic advance were carried out among 15 genotypes of chrysanthemum for characters to identify genotypes to be used in breeding programme. High PCV and GCV was recorded in fresh flower weight (GCV %: , PCV%: ) indicate the existence of wide range of genetic variability and hence there is a good scope for the improvement of these characters through selection. High heritability with high genetic advance as per cent mean was recorded in number of leaves per plant, leaf area, number of cut flowers per plant indicating the additive gene action of these characters. Exploitation of the additive variance would be possible by simple selection procedures and the mean of the trait could be shifted in a positive and desired direction. High heritability with moderate genetic advance as per cent of mean recorded in plant height (), flower diameter and days to flower bud appearance indicating the nonadditive component of variance for the character, which will not give the desirable results by simple selection. | Variability, heritability and genetic advance in chrysanthemum (Chrysanthemum morifolium Ramat.) under ecological conditions of sub-humid zone of Rajasthan
