Heterotic capability of derived inbred lines for grain yield Sorghum [Sorghum bicoJor (L.) Moench]

Published on

An attempt was made to assess the heterotic capability
of inbred lines in F
s generation of a sorghum [Sorghum
bicolor (L.) Moench] cross 3660 B x MR-750. Seventy-three
inbred lines in F
s generation were crossed to 296A, a
well-known male sterile tester to develop 73 derived F1s.
The hybrids exhibited desirable transgressive segregation
for grain yield and some hybrids were even better than
cbmmercial check (CSH 5) for their per se performance.
This implied that lines with improved heterotic capability
could be found in progenies from cross of two elite lines
in sorghum.
