花生杂交育种是创造新品种的有效方法之一,我所已进行了十多年,虽然取得一定成果,但还不能适应花生生产发展的需要。关键问题在于选配和选择过程,多凭经验,缺乏科学的预见性。在杂种分离世代,经常看到的现象是:个体间性状变异呈现连续性和多样性;有些早期世代表现良好的材料,可能随世代的递增而变劣等等。这些都给正确的选择带来一定的困难。 Peanut cross breeding is one of the effective ways to create new varieties. I have been in the field for more than ten years. Although some achievements have been made, it still can not meet the needs of peanut production and development. The key issue is the matching and selection process, which is based on experience and lack of scientific predictability. In hybrid generation, what we often see are: the continuity and diversity of trait variation among individuals; some well-behaved materials of early generation may deteriorate with age, and so on. All these bring certain difficulties to the correct choice.
