摘要
论述黑龙江省大豆品种更替过程中主要农艺性状的遗传改进和演化趋势。总的趋势是株高、百粒重、品质、产量均有不同程度的增长和改善,生育日数略有下降,亚有限结荚习性品种逐渐占据主体。
Genetic improvement and evolution tendency for main agronomic charaters of soybean cultivars renewed in Heilongjiang province were reviewed in this article. The general tendency showed that plant height, 100 seed weight,quality and yield were all increased and improved in defferent levels. Days from e mergency to maturity had little descended. Indeterminate type of soybean cultivars gradually occupied mostly parts.
