“…Days to curd initiation, curd circumference, total plant weight, curd width, curd length, curd weight, days to curd formation, days to harvest, and core length are all significantly and positively correlated with leaves/plant. Shree et al [37] revealed that the magnitude of phenotypic correlation was lower than that of genotypic for all the characters which showed the inherent association between various traits. Path coefficient analysis at both phenotypic and genotypic levels revealed that the marketable curd weight had maximum positive and direct contribution towards net curd weight followed by leaf length.…”

“…Additionally, research showed that these features have a broad genetic base, little environmental effect, and are governed by additive genes, indicating that there is considerable potential for further developing these traits via selection. Shree et al [37] studied 13 genotypes of cauliflower for a variety of horticultural traits. For marketable curd, net curd weight, and curd compactness, PCV and GCV were high.…”

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.
