autopolyploid

The results show: ①Most progenies of self-bred autopolyploid still keep the original ploidy except a few progenies;

结果表明：①同源多倍体自交后分会保持其原来倍性，但会有个别变化；

For crop improvement，haploidy enables the achievement of rapid homozygosity, enhanced selection efficiency for recessive genes, and breeding at a diallelic state for autopolyploid species.

在作改良中，单倍体可以快速得到纯合体、提高隐性基择效果及在双等位基条件下培育同源多倍体品种。
