对已退化的育成晚籼品种平朝九号花粉植株二代群体及对照的比较试验发现,花粉二代植株在所研究的各种性状上均表现整齐一致,其标准偏差(S)及变异系数(C.V.)均比对照小,而各种性状均表现比对照优越。得出对已退化的育成品种进行花药培养可以起到提纯选优的作用。花药培养可以作为农作物品种提纯选优的一种多快好省的新方法。
A comparative study on the second generation pollen plants of the degenerated late indica rice variety Pingjian 9 and the control showed that the pollen second generation plants showed uniform and consistent characteristics on all the traits studied. The standard deviation (S) and coefficient of variation (CV) were smaller than the control, and all traits showed superior than the control. It is concluded that the anther culture of the degenerated bred varieties can play the role of purification and optimization. Anther culture can be used as a new method for purification and optimization of crop varieties.
