拓宽大豆育种的遗传基础,广泛利用和创造出新种质资源,是目前提高大豆育种水平的重要途径。 黑龙江省农科院豆类资源室,从1981年以来,通过栽培大豆(G·max)与野生大豆(G·soja),半野生大豆(G·gracilis)进行种间杂交、回交、复合杂交等,现已创造和选育出秆强多荚丰产类型和多分枝多荚特用极小粒类型等不同熟期种间杂交新种质,经八五国家科技攻关有关单位鉴定,确认为中国优异野
Broaden the genetic basis of soybean breeding, extensive use and create new germplasm resources, is an important way to improve the level of soybean breeding. Since 1981, Heilongjiang Provincial Academy of Agricultural Sciences has conducted interspecific hybridization, backcrossing and compound crossbreeding with G · soja and G · gracilis cultivated soybean (G · max) Etc. We have now created and bred new germplasms of hybrids with different maturity, such as stout and strong multi-pod yield types and multi-branch and multi-pod special minipigs types, which have been identified as excellent in China after being recognized by the relevant scientific and technological units of 85th Five-Year Plan wild
