我们从70年代起选育推广了6625和大荚箭豌两个箭筈豌豆品种,先后在我国南方农区应用取得成功。前者虽然成熟期早,但耐寒性稍差,鲜草产量也较低;后者产量虽较高,耐寒性亦较好,但成熟期偏迟,易受梅雨影响,种子产量不高。为了克服这些缺点,近年来我们采用引种驯化、有性杂交等多种方法,选育成功了一批新品系,本文介绍新品系80-142的选育经过及其推广应用效果。 一、选育经过及应用效果 1980年我们从澳大利亚引入巢菜属品种 Since the 1970s, we have popularized and popularized two arrowhead pea varieties of 6625 and Pekinese, and succeeded in applying them to the agricultural areas in southern China. Although the former matured early, but a bit cold hardy, fresh grass yield is low; the latter, although the yield is higher, cold tolerance is better, but the late maturity, susceptible to the impact of the rain, the seed yield is not high. In order to overcome these shortcomings, in recent years we adopt a variety of methods such as introduction and domestication, sexual crossbreeding, breeding a number of new lines, this article describes the new line 80-142 after breeding and its application effect. First, after breeding and application effects In 1980 we introduced from Australia vetiver varieties
