| 摘 要： | 为了改良寒地超高产水稻品质,以黑龙江省10个直立穗型和32个弯曲穗型水稻品种为材料,比较了寒地不同穗型水稻品种的产量和品质差异。结果表明:直立穗型品种产量极显著高于弯曲穗型,具有较高的穗粒数是其产量高于弯曲穗型品种的主要原因。直立穗型品种糙米率显著高于弯曲穗型,直链淀粉含量显著低于弯曲穗型,其它品质指标与弯曲穗型无显著差异。

| Abstract: | In order to improve the quality of super-high-yield rice in cold region,taking 10 rice varieties with erect panicle and 32 rice varieties with curve panicle in Heilongjiang province as materials,the difference about yield and quality of rice varieties with different panicle in cold region were compared.The results showed that the yield of erect panicle type was significantly higher than that of curved panicle type.The main reason was that the erect panicle type had larger grain number per spike.The brown rice rate of erect panicle type was significantly higher than that of curved panicle type.Amylose content of erect panicle type was significantly lower than that of curved panicle type,and other quality indexes had no significant difference from curved panicle type. |
