studied for heterosis and heterobeltiosis. The magnitudes of heterosis
(mid-parent) and heterobeltiosis (better-parent) from F1 were
calculated for days to heading, flag leaf area, plant height, spike length, days
to maturity and harvest index. All the 56 F1 hybrids and their
parents were planted in a randomized complete block design in three replicates.
Out of the 56 F1 hybrids, 18 and 16 hybrids for days to heading; 11
and 2 for flag leaf area; 24 and 15 for spike length; 8 and 3 for days to
maturity and in 3 and 1 for harvest index expressed significant heterosis and
heterobeltiosis, respectively. Maximum limits of heterobeltiosis for flag leaf
area, spike length, harvest index, plant height, days to heading and days to
maturity were 22.3, 13.03, 11.23, 3.27, 2.60 and 1.82%, respectively. Among
parent cultivars, Takbeer, Inqilab-91, Tatara and Idaho-458 proved to be
superior combiners. Populations of Tatara x Khattakwal, Takbeer x Inqilab-91,
Idaho-458 x Fakhre Sarhad, Fakhre Sarhad x Takbeer and Ghaznav-98 x Takbeer were
the best for most of the traits and their use in breeding programmes is
suggested.]]>Pal, B.P. and S.M. Sikka, 19561695193Patil, V.R., S.C. Desale and S.S. Mehetre,199811285289Khan, N.U., M.S. Swati, G. Hassan and Q.
