CONSEQUENCES OF ENFORCED INBREEDING ON OVULE DEVELOPMENT IN CERTAIN OUTCROSSING POPULATIONS OF INDIAN RAPESEED (BRASSICA CAMPESTRIS L. PRAIN)

Published on

Among the open pollinated varieties of Indian rapeseed stlldied, the depressing effect of
enforced seifing on ovule size was observed to vary between 9.9% in toria variety D.T.S. to
2.10/. inthl! yellow seeded variety Sinoy. The mean value of inbreeding depression was
7.0% in toria, 4.4% in brown sarson and 2.0% in yellow sarson. The trend of the depressing
effect on the ovule developml!nt was also reflected in the similar magnitude in respect of
seeds/siliqua, l000-seed weight and oil content.
