通过国内外1800余个春、夏大豆品种研究,筛选出一批具有不同优良性状的育种亲本。在此基础上,采用夏豆×春豆单交,(夏豆×春豆)×(春豆×春豆)复交等手段,创造新的变异类型;改进杂交技术,提高杂交成活率;选择与加代同步,鉴定与繁殖同步,区试与示范栽培同步,提高了育种效率。已育成了适宜南方春大豆多熟制种植的春大豆高产品种宁镇1号和一批优良品系,分别参加国家级和省级区域试验。本文对春大豆育种方法及途径作初步探讨。
Through the research of more than 1800 varieties of spring and summer soybean at home and abroad, a batch of breeding parents with different excellent traits were screened out. On this basis, the new mutation types were created by the means of single crossbreeding of Xiaodou × spring bean, (Xiaodou × spring bean) × (Spring bean × spring peach), and the like; improved the hybridization technique to improve the survival rate of hybridization; Synchronization, identification and reproduction synchronization, regional trial and demonstration of cultivation synchronization, improve breeding efficiency. A high-yielding spring soybean variety Ningzhen No.1 and a number of excellent lines suitable for planting more spring soybean in the South have been bred and participated in the national and provincial regional trials respectively. In this paper, spring soybean breeding methods and ways to make a preliminary discussion.
