Pedigree analysis of sesame cultivars released in China
摘要
Abstract
To provide valuable clues for sesame breeding,pedigree of sesame cultivars released during 1960 -2013 in China were analyzed. Totally 145 cultivars were bred in the past 60 years,of which 136 were conventional cultivars and 9 were F1 hybrids. Since the first hybrid released in 1993,the number of hybrid cultivars had in-creased steadily,which indicating sesame prevalence of heterosis utilization. Of the 145 cultivars,121 were classi-fied as white seed - coat color,17 black,and 7 yellow or brown,exhibiting the diversification of cultivar type in term of seed - coat color. 134 cultivars with known pedigree showed that they were derived from 98 parental lines which could be further traced back to 45 Chinese landraces and 9 alien accessions. They suggested that Chinese landraces had large contribution to breeding,and that the alien gene pool had yet to be fully exploited. Yuzhi 4, Ezhi 1(old)and Yiyangbai were the most important parents used for sesame breeding in China,with 29,18 and 10 cultivars derived from the 3 parents respectively. Pedigree analysis revealed that the best way to breed an out-standing sesame cultivar was to cross the elite parents from different geographical region and / or bearing distinct but complementary botanical traits.关键词
