Major agronomic characters and their correlation coefficient in forage rape varieties

This study was carried out for estimating genetic parameters, such as heritabilities, the phenotypic and genotypic correlations of major agronomic characters with 17 cultivars in forage rape. Heritabilities of plant length, number of main stem leaves, fresh yield, total dry matter yield, stem dry matter yield, and leaf dry matter yield were higher, but that of stem diameter were relatively lower. The genotypic correlation coefficients between total dry matter yield and plant length, stem diameter, number of main stem leaves, fresh yield, stem dry matter yield and leaf dry matter yield showed highly positive correlation, those characters gave high direct effect as same level in path coefficient analysis.
