Morphometric study for varietal identification of oleiferous Brassicas

Preliminary observations recorded on eleven genotypes of oleiferous brassicas revealed that plant height is not necessarily correlated with length of raceme on main shoot. However a negative correlation between length of raceme on main shoot and number of secondary branches per plant was seen in all eleven genotypes under present investigation. The lowest angle of pod with respect to main axis is associated with non-shattering character. Thus B. napus is shattering type and B. nigra with lowest angle is least shattering type. Number of seeds per siliqua is not always associated with siliqua length. Thus B. napus having longest pods contain less seeds than B. campestris var. toria having medium size pods. Flower observation reveals that larger petal size is associated with predominantly cross-pollinated character and longer stamens were found in all the self incompatible and diploid genotypes.
