Association and path coefficient analysis in Indian mustard genotypes

Abstract

Indian mustard is the prime oilseed crop of the country. The present investigation was carried out with 38 Indian mustard genotypes laid in RCBD. Each genotype was collected with 16 yield and attributing observations for statistical analysis. The correlation coefficients revealed that, the trait seed yield was positively associated with biological yield, economical yield and oil yield similarly, negatively associated with seeds per silique and oil content. The trait, oil yield registered positively significant association with biological yield, economical yield, seed yield and negative significant association with seeds per silique and oil content. The traits oil yield, number of primary branches per plant and biological yield registered high direct effects and could be employed in direct selection for seed yield due to high direct effects. In selection for oil yield, the traits viz., seed yield, oil content, economical yield and days to 50 per cent flowering can be employed.
