随着生产的发展和生活水平的提高,人们对杂交稻单产和稻米品质要求越来越高。要在汕优63基础上实现产量再次突破,众多育种家提出种种设想,概括起来有:(1)重塑株型;(2)利用亚种间杂交产生的强优势;(3)株型与优势相结合。我所自成功选育汕优63、威优77、特优70等籼稻组合以来,继续探索新的育种方法与途径。借鉴杨振玉、黄耀祥等先生提出的理论,从强优势利用着
With the development of production and the improvement of living standards, people are demanding higher and higher yield of hybrid rice and rice quality. To achieve a breakthrough once again on the basis of Shanyou 63, many breeders have come up with various ideas that can be summed up as follows: (1) remodeling of plant types; (2) use of strong advantages derived from cross between subspecies; (3) The combination of advantages. Since successful selection of Shanyou 63, Weiyou 77, Teyou 70 and other indica combinations, we have continued to explore new breeding methods and approaches. Learn from Yang Zhenyu, Huang Yaoxiang and other theories put forward by the strong advantage of the use of
