STUDY OF INBREEDING DEPRESSION FROM Fl TO F3 GENERATION IN SOME INTERVARIETAL CROSSES OF INDIAN RAPESEED B. CAMPESTRIS L. PRAIN

Published on

Among 28 intervarietal crosses studied, the average inbreeding depression for seed yield
from Fl to Fz generation was 14.74%, and from Fz to F3 6.09o/D. The mean inbreeding
depression for the major yield components (except lOOO-seed weight) in the high range. The
cross combinations Candle X Torch, YST-151 x Candle, and PT-30 X Candle could be
considered to be desirable crosses from the composite breeding point of view.
