HETEROSIS IN FODDER TRAITS OF SORGHUM

Abstract

                                Forty two hybrid combinations and their parents were evaluated for heterosis in fodder yield and their component characters. Observations were recorded on six characters namely plant height, number of leaves, leaf-shoot ratio, total soluble solids, crude protein yield, and dry matter production. Significant heterosis was recorded by all hybrids over mid-parent for plant height. For dry matter production yield 3660 A x M 35-1 and 2077 A x M 35-1 exhibited maximum heterobel tiosis. The cross combination 3660 A x Co 23 expressed maximum heterobeltiosis for plant height. The hybrid combination such as 2077 A x FS.1, 2077 Ax M 35-1, 2077A x K7 3660 A x Co 25 and 2219 A x FS, are all worth for pursuing for their best per se performance for plant height crude protein yield, total soluble solids and dry matter production
