Abstract:
The estimation of standard heterosis over two popular checks, DHM 121 (local) Bio 9544 (national), revealed standard heterosis up to 28.99% for yield per plant over the better check DHM 121 (133.67 g) and twelve hybrids with more than 10% yield heterosis were identified. With respect to number of kernels per row, as many as 50 hybrids exhibited significant superior heterosis over the better check DHM 121.The evaluation of fresh single cross hybrids, as a whole, on the basis of performance and standard heterosis over the better check DHM 121 with respect to yield per plant and other yield contributing characters, six superior hybrids have been enlisted viz., N 128, N 137, N 122, N 130, N 104 and N 191. These crosses may be directly used as single cross hybrids after evaluation in multilocation trials or their homozygous inbred lines may be used in further breeding programmes.
