*Part of a thesis submitted to TNAU in partial fulfilment of the requirements of the Ph.D. Degree by RAM NATH KAW in 1972. Abstract In a 10-variety diallel cross in soybean, both gca and sca variances were found to be highly significant for six developmental characters. Parental performance as judged by gca effects indicated that ‘EG 7034’, ‘EG 27500’, ‘Hernon-49’, ‘EG 39822’ and ‘EG 39821’ were good general combiners for different characters. In general, the superior combinations involved at least one high general combining parent. Top |
