Abstract: Heterotic and heterobeltiotic performance of 28 F1's obtained through
crossing 8 commercial varieties, were evaluated for days to heading,
days to maturity, tillers per plant, flag leaf area, plant height, spike
length, grains per spike, 1000 grains weight, harvest index and yield
per plant. The highest heterotic and heterobeltiotic interactions were
recorded in GZ x Der (-5.35 and -4.98%) for days to heading, Tat X SQ
(-2.16 and -1.21%) for days to maturity, GZ x Tat (14.92 and 7.46%)
for tillers/ plant, SQ x ICP (17.14 and 14.01%) for flag leaf area,
Tat x Sar (-3.29 and -2.89%) for plant height, SQ x Der (19.11 and 16.21%)
for spike length, Sar x Der (23.14 and 17.60%) for grains per spike,
Tkb x Der (28.42 and 28.0%) for 1000 grain weight, SQ x ICP (24.69 and
21.68%) for harvest index and Tat x SQ (56.25 and 26.87%) for yield
per plant, respectively. The results revealed that the hybrid combinations
Tat x SQ and SQ x ICP could be recommended for improved yield and enhanced
biological production of wheat, respectively.
