    摘要:

    对“十五”期间存入国家种质库的532份高粱种质资源的粗蛋白、粗淀粉、赖氨酸、单宁等四个主要品质性状进行了鉴定评价和相互关系分析。结果表明,四个主要品质的含量呈现近似正态分布。不同品质性状变异程度不同,其中单宁含量变异最大。性状间存在着不同的相关性。不同来源的种质品质性状比较结果表明,选育品种的赖氨酸、单宁含量明优于地方品种。通过鉴定,筛选出一批多项、双项或单项品质优良的高粱种质资源。

    Abstract:

    Identification and evaluation of 532 sorghum accessions newly stored in the National Genebank during 2001-2003 have been carried out with respect to four quality traits of protein,starch,lysine and tannin content. Furthermore, the correlations between quality traits of sorghum accessions were calculated. The results showed that characters of four quality traits appeared to be normal distribution, respectively. The different variations of the traits of sorghum accessions were revealed, therein, tannin content varied most. And among the four traits existed different relationships. Comparing with each quality trait of sorghum accessions of different origins, it could be found that lysine and tannin quality characters of bred sorghum were superior to that of landraces. Therefore, several high grade sorghum accessions possessing one or two even more good quality traits had been singled out through screening.
