通过花药培养诱导获得的花粉植株,从理论上说,经染色体加倍结实,其遗传基础是纯合的,因此,后代不应该发生性状分离。然而,据近年来的不少研究报告指出,在水稻及小麦的花粉植株后代中,却由于经常出现不同程度的性状分离而使一些经济性状优良的株系失去其育种应用的价值。这就不免有人因此而对花药培养花粉单倍体育种 Pollen plants induced by anther culture, theoretically, are more homozygous for chromosome doubling and are therefore homozygous for genetic segregation of offspring. However, many studies in recent years have pointed out that in the offspring of pollen plants of rice and wheat, some lines with good economic traits have lost the value of their breeding due to the frequent occurrence of segregation of different traits. This inevitably led some people to cultivate anther pollen haploid breeding
