特优系列组合杂种优势较强,但其不育系龙特浦A有少量自交结实现象,制种纯度不稳定。因此,在生产上应用时,首先要针对特A育性不稳定的特性,加强提纯繁殖,用原种直接制种,将制种时间安排在特A育性相对比较稳定的中晚造进行,并加强除杂去劣,以确保杂交一代种子纯度;在此基础上,大力推广各项先进适用技术,实现良种良法配套。
The superior hybrids had stronger heterosis, but its sterile line Longtepu A had a few self-fertility and seed-setting instability. Therefore, in the application of production, we must first focus on the special characteristics of fertility instability, to enhance the purification and breeding, the direct seed production with the original species, seed production schedule in special A fertility is relatively stable in the late made, And to strengthen the removal of impurities to ensure the purity of the hybrid generation of seeds; on this basis, vigorously promote the application of advanced technologies to achieve good varieties of good equipment.
