Abstract: Differences in grain characters and grain moisture contents (%) during filling period between 4 pairs of waxy and nonwaxy near isogenic lines were studied. The results showed that moisture content (%) of waxy grain was higher than that of nonwaxy ones during 24 days after flowering through maturity, which might caused waxy lines lower in 1000 grain weight, specific gravity of grain, 1000 kernal weight and kernal size. The yearly-stored seed of waxy lines have lower germination rate and germinating viability in comparison with nonwaxy one.

Key words: Germination rate, Germinating viability, Kernal moisture content, Near isogenic lines, Waxy gene
