湘两优糯粱一号品种特性与再生技术研究

湘两优糯粱一号是利用高粱温光互作核不育原理，用湘糯梁 S-1与湘10721品种杂交而成的世界上第一个两系法选配的高粱新品种。它的杂种优势，品种特性，秋茬再生能力与其他常规品种有何差异？尤其是常规品种在本地只种春季一茬，不存在秋季再生的情况下，如何根据浙江省的气候，科学确定春茬砍杆时间和秋季再生茬安全抽穗时间，以及相应的秋季配套技术，是作者本文的研究目的。经过作者5年的试验研究，在摸清了该组合生育期短、茎杆粗壮、株型紧凑、杂种优势显著、适应性广、产量高和再生能力极强等特性后，进而研究与掌握了春茬收获时间、低茬秋季再生技术

The Studies of Variety Character and Reproduction Techniques of Glutinous Sorghum Variety Xiangliangyou 1

Glutinous sorghum variety XiangLiangYou1 is bred through crossing the XiangGlutinousSorghums-1 and Xiang 10721, by the theory of making nucleas steril with the effect of temperature and ray .it’s the first new variety in the world which is bred by two-systems method .what is it different from the other generic varieties about hybrid preponderance ,variety’s characteristic and autuman -patch’s ability of regeneration ? Moreover ,the native usually only plants the spring-patch and no autuman-patch. In this article , the aim of author is how to confirm the time of cutting the spring-patch and the time of making autuman-patch grow spike safely according to ZheJiang climate. After doing experiment and researching for 5 years ,the author has cleared that this double have strong stems, compact figure ,distinct hybrid preponderance ,wide adaptability ,high yield ,strong regenerantion and their growing time is short .the author has grasped how to confirm the harvest-time of spring-patch and the technology of regeneration of autuman-patch.
