通过多年试验研究,作者初步认为,象水稻这种天然孤雌生殖发生机率极低的作物,用人工激素诱导,虽能产生单倍体植株,但诱导率很低,有些有育种价值的组合反而诱导不出来,这就限制了在育种 Through many years of experimental research, the authors initially believe that, like rice, the natural parthenogenesis of crops with very low probability of induced by artificial hormones, although can produce haploid plants, but the induction rate is very low, some combinations of breeding value instead Induction does not come out, which limits the breeding
