摘要

F1 hybrids of a set of crosses involving the highly-responding japonica cultivar, Taipei 309, and 3 low-responding indica cultivars (IR72, IR64 and IR54), as well as the parents were studied for their response to anther culture in terms of callus induction and plant regeneration frequency. Diallel analysis revealed the high-response in Taipei 309 to be governed predominantly by recessive alleles as against the low-responding indica cultivars which were largely due to dominant alleles. Although it was not possible to precisely determine the number of genes that control anther culture response, it was demonstrated that these traits followed quantitative mode of inheritance. Estimates of genetic components of variation for callus induction revealed that additive variance largely govern the response indices, suggesting thereby that transfer of the high callusing ability of Taipei 309 to low-responding genotypes by simple selection techniques should be feasible.
