利用制啤质量达国际优级的材料和高抗黄花叶病的材料为母本与丰产性、抗逆性好的材料配制杂交组合，培养它们的Ｆ２代花药，获得大量加倍单倍体纯合稳定群体，可大大缩短育种周期，且花培后代不存在显性性状掩盖隐性性状的问题，丰富多样的小孢子重组体能充分在后代显现，从而
Utilizing the material with international quality grade and high resistance to yellow mosaic virus as the female parent and the high yielding and good resistance material, the hybrid combinations were prepared and their F2 anthers were cultured to obtain a large amount of haploid homozygous Stable population can greatly shorten the breeding cycle, and there is no obvious trait in the germplasm to cover the hidden traits. The rich and diverse microspore recombinants can be fully demonstrated in the offspring and thus
