Variability studies in cauliflower (Brassica oleracea L. var. botrytis L.) for horticultural traits under mid hill conditions of North-Western Himalayas, India

Abstract

The present investigation was undertaken to assess the variability, heritability and genetic advance in late maturing group of cauliflower. The experiment was undertaken in Randomized Block Design (RBD) with three replications at the Experimental Farm of the Department of Vegetable Science and Floriculture, CSK HPKV Palampur. Twenty five genotypes of cauliflower were evaluated including Madhuri as check during Rabi season of 2014-15. Analysis of variance revealed significant variability for most of the traits. High estimates of PCV and GCV were observed for curd solidity indicated that there is substantial variability ensuring ample scope for improvement of this trait through selection. High heritability coupled with high genetic advance was observed for ascorbic acid content and curd solidity. The result suggested the importance of additive gene action for the inheritance of these characters thus improvement can be brought about by phenotypic selection for these characters.
