摘要: 以34个黑龙江省第三积温带推广的水稻品种为材料,比较了寒地水稻不同穗型品种产量、品质的差异。结果表明,水稻产量表现为密穗型>中穗型>稀穗型的趋势。密穗型品种的每穗粒数、一二次枝梗数和一二次枝梗粒数均高于稀穗型和中穗型品种。稻米品质中,蛋白质含量表现为密穗型>中穗型>稀穗型,直链淀粉含量和米饭食味评分与蛋白质含量的表现相反。

Abstract: The yield and quality of different panicle type rice in cold region was compared, with 34 rice varieties in the third accumulated temperature belt of Heilongjiang Province as materials. The results showed that the grain yield performance dense panicle type > semi panicle type > loose panicle type. The grains per spike, the numbers of first and secondary branches and grains of dense panicle type varieties were higher than that of loose panicle type rice and semi panicle type rice. The protein content performance dense panicle type> semi panicle type > loose panicle type. The amylose content and taste value is opposite with the protein content.

Key words: cold area, rice, panicle type, yield , quality
