远缘杂交的研究,对于物种形成、系统发育、遗传性及变异性关系的建立以及引种的理论和实践等问题均具有特别重要的意义。我们于1970年开始进行春小麦与豌豆的远缘杂交工作,目的是想把豌豆的早熟、粒大、粒重的优良特性结合在小麦上,培育出适应高寒地区早熟稳产的春小麦新品种。几年来已获得一些品系,有的品系已接近育种目标,经过试种受到群众的好评,现将这项工作简要报道如下。
The study of distant hybridization has particular significance for the formation of species, phylogeny, establishment of the relationship between heredity and variability, as well as the introduction of theory and practice. We started the distant hybridization between spring wheat and pea in 1970 in order to combine the good characteristics of early maturity, grain size and grain weight of peas with wheat to cultivate new spring wheat varieties that adapt to precocious and stable production in the alpine region. In recent years, some lines have been obtained. Some lines are close to the goal of breeding and have been well received by the masses after trial planting. The work is briefly reported as follows.
