Among the yield components, decreases in number of panicles per pot and seed setting rate were two main reasons for the yield reduction.
在产量构成因子中，每盆穗数和结实率是影响产量的两个主要因子。
The seed setting rate has no obvious difference between autotriploid and autotetraploid, but it will rise with the increase of the self-bred generations.
③同源三倍体和同源四倍体之间的自交结实率没有明显的区别，结实率会随着自交代数的增加而上升。
The major differences between them were the plant height, effective panicle number, total grain number per panicle, number of filled grains per panicle, seed setting rate and 1000grain weight.
最主要的差别在株高、有效穗、每穗粒数、每穗实粒数、结实率和千粒重等几个性状。
