Genetic variability and character association for yield and quality traits in early maturing Indian cauliflowers

Abstract

Significant differences were observed among genotypes in early Indian cauliflower suggesting sufficient variability for yield and quality characters. The genotypes DC-98-4, DC-98-10 and DC-124 were found superior with respect to yield and quality characters. The overall values of PCV were higher than those of GCV. The highest estimate of GCV was observed for vitamin C contents (54.58) followed by duration of curd availability (49.04), while highest heritability was recorded for days to 50% curd formation (0.992). High heritability along with high genetic advance as per cent of mean was estimated for curd compactness, net curd weight and vitamin C content. Total yield had significant positive correlation with net curd weight and harvest index. However, yield was negatively correlated with duration of curd availability and days to 50% curd formation. Path coefficient analysis revealed that net curd weight and curd compactness had the highest positive contribution towards the total yield respectively.
