黑龙江省第二积温带水稻产量性状分析
Analysis on Yield Traits and Relationship of Rice of the Second Accumulated Temperature Zone in Heilongjiang Province
摘要
Abstract
In order to clarify the breeding objectives of the second accumulated temperature zone in Heilongjiang Province, the author analyzed the yield traits and relationship of 30 rice varieties of the second accumulated temperature zone. The results showed that the main factors affecting the rice yield are grain number per spike, leaf width, thousand grain weight, ear length, seed setting rate and plant height. In the future, we should carry out high yield breeding on the basis of improve rice plant type and increase grains per panicle.关键词
