摘要
The extent of seed size variations within a rice variety and its effect on germination and seedling vigour were investigated. Seed size was determined by weighing individual grains of randomly selected one hundred panicles. Grains were sorted into four size classes: 11-15, 16-20, 21-25 and 25-30 mg. There was nearly a three-fold variation between the smallest and the largest seeds, which ranged from 11 to 30 mg. Germination rate and seedling vigour index values increased with the increase of seed size suggesting the selection of larger seeds for good stand establishment.
