“…High heritability along with moderate genetic advance were observed for marketable weight of curd, curd compactness, plant height and length of leaves which pointed towards the occurrence of additive gene action and hence phenotypic selection as such might be effective for improvement of these traits. These results were in close proximity with the findings of Chittora and Singh (2015) and Chatterjee et al, (2018) in cauliflower. High heritability coupled with low genetic advance was observed curd maturity duration and number of leaves per plant.…”

“…This is an indication of existence of sufficient amount of variability exist for in red cabbage. Similar results were determined by researchers examining different morphological traits in different Brassica species (Kibar et al, 2014;Thakur & Vidyasagar, 2016;Chatterjee et al, 2018;Aktar et al, 2019). Variability is the most important characteristic feature of any population is of remarkable importance in breeding programme.…”

Genetic variability, heritability, genetic advance, genetic gain and correlation for seven different traits were studied in 22 genotypes of red cabbage. The genotypes were evaluated for seven quantitative characters such as head weight, head diameter, head length, core length, head volume, head density and head shape index. Analysis of variance showed significant variation among the genotypes for all the studied yield and yield contributing characters. Head weight of the lines was highly significant positively correlated with head length, head diameter, core length and head volume. The phenotypic coefficient of variation were observed to be higher than the corresponding genotypic coefficient of variation for all the characters studied, indicated that the traits were influenced by environment. The high phenotypic and genotypic coefficient (PCV and GCV) was observed for head density (30.61 and 20.06) followed by head volume (24.72 and 20.49), core length (15.68 and 14.99) and head weight (10.66 and 9.65). Heritability was high for majority of the traits. High heritability (broad sense) values were recorded for traits such as for head length (91.56%), core length (91.38%) and head diameter (82.24%). The highest genetic advance as percent of mean was shown by head volume (35.0 %) followed by core length (29.52%) and head density (27.09%). As a result, high heritability coupled with high genetic advance was observed head length, head diameter, head volume and head density which are governed by additive gene and could be effectively used as selection criteria in the breeding programme of red cabbage varieties with high yield.

“…Chatterjee et al [35] evaluated 20 mid-late and late groups of cauliflower genotypes in order to determine the nature and magnitude of genetic variability, heritability, and genetic gain for the characters viz., leaves per plant, stalk length, days to marketable curd maturity from the date of transplanting, gross plant weight, plant height, curd depth, curd size index, leaf size index, curd solidity and marketable plant yield. The Curd size index showed high heritability and high genetic gain, while leaves/plant, curd depth, leaf size index, gross plant weight, and marketable plant yield showed high heritability and moderate genetic gain.…”

“…The path analysis determines the association's relative relevance and determines the magnitude of the direct and indirect impacts of causative factors on the yield [15]. Therefore, choosing appropriate plant types for a successful breeding program requires the evaluation of correlation and path coefficients between yield and its associated attributes.For the selection of desirable genotypes having higher productivity, the curd yield and related characteristics provide important criteria [16] which could be achieved, to analyze the genetic variability in the cauliflower genotypes, by planning an initial breeding program [17].…”

The constant availability of high-yielding and well-adapted varieties is made possible by a vigorous breeding program and it is the first and least expensive input in improving the output of any crop. To design breeding methods for the development of a certain crop, it is essential to have a thorough understanding of genetic variations, correlations between various traits, and their direct and indirect contributions to yield. The amount of genetic variability and character outstanding from one generation to the next determine how much a crop may progress genetically. Because phenotypic selection relies on the range of genetic variability available in the population, it is necessary to separate the variability into heritable and non-heritable components. This will increase the reliability of the selection. Curd yield in cauliflower is a complicated trait that is greatly impacted by the environment since it is regulated by several genes. Some of the component qualities may be directly and favourably correlated with the marketable curd weight, making them suitable for use as selection criteria in crop improvement programs. Characters having a strong and positive/desirable correlation to one another would be used to boost yield effectively. The proper weightage for selection purposes is also determined by the proportional contribution of the component qualities to the yield. The level of genetic diversity contained in a specific crop determines the most appropriate varietal development programs.
