绥农号大豆血缘关系分析

通过对21个绥农号大豆品种进行系谱分析，明确了采用当地早熟、高产、优质种质资源作为骨干亲本，加入国外血缘，改进血缘狭窄，丰富遗传基础，是育种成功的关键所在；三交组合方式后代类型丰富，易于选出丰产性突出、熟期适中、抗病性及适应性好的优良品种和材料；在育种过程中要注重创造亲本材料。

Pedigree Analysis of Soybean Cultivars Named by Suinong

The pedigrees of 21 soybean cultivars named by Suinong were analyzed. There are 2 keys of successful breeding. First, fine germplasms with early maturity and high yielding are adopted as main parents. Second, exotic germplasms are introduced and genetic bases are enriched. The generative types of triple crosses are plentiful, and it is easy to select cultivars and lines with super yield, medium maturity, diseases resistance and wide adaptivity. Thus we should pay attention to creating materials for crossing parents.
