“超级稻”选育成功具有十分重大的意义。从光合潜力分析,成都这样的全国低日照地区开展“超级稻”选育也是能够成功的。笔者深入分析了第一次绿色革命——矮秆多穗育种和半矮秆穗粒兼顾育种是以不断提高经济系数作为主要增产途径,并基本达到极限的基础上,提出了“超级稻”的选育(即第二次绿色革命)应以大幅度提高生物学产量作为主要增产途径,应以“中秆强分蘖大穗育种”和“中高秆强分蘖超大穗育种”为选育的主要途径的新观点。在此基础上,制定了“利用亚种间杂种优势选育‘超级稻’”的技术路线,设计了育种目标,进行了育种新材料的研制、引进和配组杂交。鉴于两批杂交组合后代都达到了预期目标,目前正采用组群筛选法抓紧选育工作,力争在较短的时期内育成800kg/667m~2或更高产的优质“超级稻”品种,为水稻生产实现跨越式发展作出贡献。
“Super rice ” Breeding success is of great significance. From the photosynthetic potential analysis, it is also successful to carry out “super rice” breeding in such low-sunshine areas as Chengdu. The author deeply analyzed the first green revolution - the short stalk and multi-spike breeding and semi-dwarf spike grain taking into account the breeding is to continuously improve the economic coefficient as the main means of production, and basically reached the limit on the basis of the proposed “super rice Breeding ”(ie the second green revolution) should be to significantly increase the biological yield as a major means of production should be “ stalks and strong tillering big spike breeding ”and New ideas for the main ways of breeding. On this basis, we have formulated the technical route of breeding super rice using the heterosis among subspecies, designed the breeding target, researched and developed new breeding materials, and introduced hybridization. In view of the expected target of the two crosses, the group screening method is now being used to pay close attention to the breeding work and strive to breed 800kg / 667m ~ 2 or higher high-quality “super rice” varieties in a relatively short time, To make leapfrog development of rice production to contribute.
