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。
In order to improve the quality of super-high-yielding rice in cold region, the yield and quality of paddy rice with different panicle types in cold regions were compared using 10 erect panicle types and 32 curved panicle type rice varieties in Heilongjiang Province as materials. The results showed that the yield of erect panicle varieties was significantly higher than that of curved panicles, and the higher number of grains per spike was the main reason for higher yield than curved panicle varieties. The percentage of brown rice in erect panicle varieties was significantly higher than that in curved panicles, and the content of amylose was significantly lower than that of curved panicles. There was no significant difference in other quality indexes between panicle type and curved panicle types.
