Abstract

A diallel cross involving four rice cultivars; Basmati 370, Basmati 385, 4048 and Basmat 198 was studied in the F1 generation for anther length, 10-anther weight, pollen grain size and percent filled spikelets. Both general combining ability (GCA) and and specific combining ability (SCA) were significant for all traits except pollen grain size. The GCA mean square magnitude was considerably higher than SCA mean square for anther length and 100-anther weight. The inverse was found for percent filled spikelets. It reveals additive gene effects for anther length, 100-anther weight and dominance gene effects for percent filled spikelets. Basmati 198 displayed positive and significant general combining ability effects for anther length and 100-anther weight. Basmati 370 was the best general combiner for percent filled spikelets. 4048 x Basmati 198, Basmati 370 x 4048 and Basmati 370 x Basmati 385 were the best specific combiners for anther length, 100-anther weight percent filled spikelets respectively and are expected to contribute higher frequency of desirable plants than other crosses in subsequent generations.
