Evaluation

The seedlings selected based on vigour are field planted. On attainment of steady yield, the hybrids are evaluated for their performance. The highest yielding hybrids with other desirable attributes are multiplied and released as new clones. The parents selected in hybridization programmes are tested for both their GCA (general combining ability) and SCA (specific combining ability). To test the GCA, all the selected clones are crossed with a standard variety and the progenies are evaluated both in the nursery and in the field. A few best combiners are then selected and crossed in all possible combinations to assess their SCA. Parents of promising hybrids are identified as best combiners. The best combiners are multiplied and used as parents in seed gardens for the production of quality hybrid seeds
