IDENTIFICATION AND UTILISATION OF WIDE COMPATIBILITY GENE IN RICE
Main Article Content
Abstract
A set of indica and tropical japonica genotypes were screened for wide compatibility by crossing them with suitable japonica and indica testers. The genotypes showed variation for wide compatibility. Dular and 9314 Were found to be the ideal indica and tropical japonica 'WC' lines respectively. Pusa 743 and 9313 failed to qualify as wide compatible varieties. Wide compatible varieties when used as male parents exhibited positive effects in their hybrids in respect of some traits like number of spikelets and spikelet fertility. On account of many advantages, it is found desirable to develop tropical japonica CMS lines and TGMS lines. To exploit the positive effects of WC parents from male side, possibilities of developing both parents with 'WC' gene are suggested to develop heterotic indica Itropical japonica hybrids.
