特用大豆优质种质资源利用与创新

Innovation and Utilization of Germplasm Resources for Special Purpose Soybean

立足于目前我国农业产业结构调整大背景下,充分发挥地缘和资源优势,进行特用大豆优质种质资源的利用与创新,通过野生和半野生大豆资源的利用,拓宽大豆遗传基础,运用有性杂交、回交等技术手段,采用系谱法、混合法、单粒传法等后代群体选择方法,在广泛的后代变异中选择超亲表型,并进一步稳定成优良品系,稳定后的品系可直接利用,也可以改良后利用。本研究获得黑大豆、双青豆、纳豆、芽豆、双高大豆等特用高产大豆品系共18份,目前部分品系已用于实际生产。

Based on the agricultural structure adjustment under the background of our country, give full play to the geographical and resource advantages, put special purpose soybean germplasm resources exploitation and innovation, through the use of wild and half wild soybean resources to broaden the soybean genetic basis, by means of hybridization and backcross, using pedigree method and hybrid method, single grain preach group selection method, in a wide range of variation in the offspring choose transgressive phenotype. Further stability into superior lines, those could be directly used or improved strains. Obtained with high yield soybean lines, a total of 18. Including black soybean, green beans, natto, sprouted broad bean, and combination of soybean, at present some lines had been used in practical production.
