A COMPARISON OF TWO BREEDING PROCEDURES IN TWO CROSSES OF MUNGBEAN (VIGNA RADIATA (L.) WILCZEK)

Published on

Two breeding methods, single-seed descent (SSD) and bulk (B) were compared in the
segregating generations of two crosses (HG 19 x Black Neelalu (BN) and ML 5 x BN) of
mungbean,
Vigna radialll (L.) Wilczek. Yield trials were grown in F.. F. and F.
generations. There was no evidence for a directed
shift in mean performance for days to
maturity, No. of branches and seeds/pod. There were sporadic differences in variance
and CV estimates of bulk and SSD populations most likely due
to sampling error. The
estimates of heritabllity and genetic advance were moderate
to high, indicating that
improvement through selection would
be feasible. There was no consistent difference in
the expected genetic advance from the three SSD and the bulk populations.
