摘要
把Ⅱ-32B干种子通过返回式卫星进行搭载,利用SP3群体中获得的厚叶、半矮秆突变株与明恢86杂交,再与明恢82复交,后代连续多年在福建上杭茶地稻瘟病自然病区鉴定筛选及在福建建阳和海南三亚反复加代、定向培育和逐代稳定,育成早熟、优良恢复系福恢202。利用福恢202与广东省农科院水稻所培育的籼型优质不育系泰丰A配组育成三系杂交早籼新组合泰优202。该组合具有产量高、稳产性好、米质较优、稻瘟病抗性较强、适应性广,以及群体整齐、穗大粒多、结实率高和熟期转色好等特点,2016年通过福建省品种审定(闽审稻2016001)。介绍了泰优202的选育过程、产量表现及品种主要特征特性等,并探讨了其应用前景。
A thick-leaf,semi-dwarf mutant rice,which was obtained from the 3 rd generation plants grown from theⅡ-32 B dry seeds that had been in a satellite in space,was multi-crossed with Minghui 86 and Minghui 82 to arrive at the hybrid,Fuhui 202.Subsequently,the progeny of Fuhui 202 was planted in the rice-blast-infected field at Shanghang fora disease resistance evaluation.Then,the selected lines were repeatedly cultivated for several generations in Jianyang and Sanya to ensure a reliable cultivar stability.The resulting high-quality,early restorer line,Fuhui 202,was then crossed withthe good quality three-line male sterile Taifeng A from the Rice Research Institute of Guangdong Academy of Agricultural Sciences to breed a new early hybrid rice variety,Taiyou 202.The new hybrid rice exhibited high and stable yield,good quality,blast resistance,broad adaptability,population uniformity,large panicles withnumerousspikelets,high setting rate,and visible color change at maturation.It was certified by Fujian Crop Variety Appraisal Committee in 2016.The breeding procedures,yield performance and major characteristics,as well as the prospect for promotion of Taiyou 202 are presented.
