Abstract:

Chunjiang 88A is a Dian-type early-maturing late japonica sterile line bred by the China National Rice Research Institute. It exhibits excellent plant and leaf morphology, stable sterility, and favorable traits including early flowering, good outcrossing seed set, high 1000-grain weight, and high multiplication and seed production yield. Using Chunjiang 88A as the female parent and indica-japonica intermediate wide-compatibility restorer lines (T27, Chenghui 17, T301, T8, T6, CH7, and T45) as the male parents, seven indica-japonica hybrid rice combinations were developed: Chunyou 83, Chunchengyou 887, Chunyou 801, Chunyou 888, Chunyou 86, Chunyou 87, and Chunyou 85. All of these combinations have passed national or provincial variety approval. The Chunjiang 88A series of indica-japonica hybrid rice combinations exhibit prominent heterosis, high yield potential, good lodging resistance, excellent grain quality, high seed production yield, and wide ecological adaptability. They are suitable for cultivation in the rice-growing areas of the middle and lower reaches of the Yangtze River and have entered the stage of large-scale extension.

摘要：

春江 88A 是中国水稻研究所选育的滇型早熟晚粳不育系，其株叶形态优良、育性稳定，兼具花时早、异交结实性好、千粒重高、繁制种丰产等优良特性。以春江88A为母本，T27、诚恢17、T301、T8、T6、CH7、T45等籼粳中间型广亲和恢复系为父本，配组育成春优83、春诚优887、春优801、春优888、春优86、春优87、春优85共7个籼粳杂交稻组合，均通过国家或省级品种审定。春江88A系列籼粳杂交稻杂种优势突出、增产潜力大、抗倒性较好、米质优良、制种产量高、生态适应性广，适宜在长江中下游稻区种植，已进入大面积推广阶段。
