Abstract:
Studies on magnitude of heterosis in interspecific and intergeneric hybrids of sugarcane involving six lines (
Saccharum officinarum cv. Badila (L
1) and five sugarcane varieties
i.e., CoC671 (L
2), CoC 85061 (L
3), CoC92061 (L
4), Co86032 (L
5), CoG93076 (L
6)) and three testers [
Saccharum wild relatives,
Saccharum spontaneum (T
1)
, Erianthus arundinaceus (T
2) and
Miscanthus sacchariflorus (T
3) (latter two are related genera)] revealed pronounced hybrid vigour for cane yield and its attributes. Positive and significant relative heterosis and heterobeltiosis were recorded for number of millable cane per plot and cane yield per plot by L
1 ´ T
2 and L
5 ´ T
2. Also, L
5 ´ T
2 recorded signiicant positive relative heterosis for internode length, cane thickness, number of millable cane per plot and cane yield per plot. Above said both hybrids were recorded positive significant standard heterosis for cane length, internode length, number of millable cane per plot and cane yield per plot. In general, L
1, L
5 and T
2 were found promisng parents. The present study suggested that exploitation of L
1 ´ T
2 and L
5 ´ T
2 should be more rewarding for future sugarcane breeding.
