Forty-seven anther calli-derived dihaploid rice plants obtained from indica and japonica cultivars and F1 and F2 plants of crosses between indica/indica and indica/japonica genotypes at H1, H2 generations and eight selected dihaploids at H3 generation were evaluated in the field during T. Aman and Boro seasons. There was a wide variation among dihaploids for plant height, tiller number/hill, panicle length, spikelet number/panicle, sterility, maturity and yield. Compared to the mother plant/sister line or the check cultivars most were poor in yield. However, three anther culture (AC) lines, BR 1083-226-4-AC-lb and BR2799-10-4-6-3-AC-2 for T. Aman and IR9729-AC-la for Boro appeared better than the rest. It is suggested that further improvement of these three lines through crossing with desirable genotypes and anther culture of the F1 hybrids is possible.
