“六五”期间,经全国广大育种工作者的共同努力,我国的高粱育种工作,扭转了多年来的被动局面,取得了可喜的成果。一、高粱品种资源研究的新进展 1.中国高粱资源的研究:我国已搜集保存了大量中国高粱地方品种及部分育成的新品系。中国农科院品种资源所对65份糖高粱的鉴定分析,出汁率一般都在50～60%,高的可达70%。重庆市作物所经过几年的研究证明,四川当地的农家糯高粱品种,淀粉含量高(占60～70%),蛋白质含量适宜,单宁含量低,特别是支链淀粉含量高,β—淀 During the “65” period, thanks to the joint efforts of the breeding workers across the country, the sorghum breeding work in China reversed the passive situation over the years and made gratifying achievements. First, the sorghum varieties of new research resources 1. Sorghum resources in China: China has collected a large number of local varieties of sorghum and some bred new strains. Chinese Academy of Agricultural Sciences species and resources of 65 sorghum identification analysis, juice rates are generally 50 to 60%, up to 70%. After years of research on crops in Chongqing, it has been proved that glutinous sorghum varieties in local farmers in Sichuan Province have high starch content (60-70%), suitable protein content, low tannin content, especially high amylopectin content,
