水稻品种无论采用何种栽培方式,都必须具有较高的分蘗能力,它在保证和调整群体结构上具有决定作用,是产量构成的重要因素。关于水稻分蘗性状的遗传,前人报导认为,分蘗数目和穗数是正相关。分蘗数主要受累加基因作用的控制,多穗型对少穗型是部分显性。笔者曾通过杂种一代和亲本间分
Regardless of the cultivation method used, rice varieties must have high tillering ability, which plays a decisive role in ensuring and adjusting the population structure, and is an important factor in the yield formation. On the inheritance of rice tillering traits, reported in previous reports, the number of tillers and the number of spikes is a positive correlation. The number of tillers was mainly controlled by the addition of genes, and the more panicle type was less dominant than the less panicle type. I have passed the hybrid generation and parental sub-points
