川植3号是四川省农科院植保所1979年用“桂朝2号”作母本,“I R2061—404—2—4—5”作父本杂交,历年经浦江病圃早代株系鉴定选择,于1984年稳定。稻瘟病大流行的1985年,全省区域性试验表明,本品种既保留了桂朝2号高产性能,又结合进了“IR2061—461—2—4—5”的抗病性和米质好等优良性状,属中籼中熟品种。全省两年区域性试验平均亩产498公斤,最高产量574.9公斤,与对照种沪科3号相当。对稻瘟病抗性强,病区种植增产潜力大,在省区试的稻瘟病区川西片较对照种增产12.4％。川植3号叶色较浅,叶姿挺直、窄立、株型松散适度,具有抗病虫特征。在浅山、丘陵区种植对稻瘟病流行有抑制作用。1959年通过四川省品种审定委员会审定。
Chuanzhi 3 is Sichuan Academy of Agricultural Sciences Plant Protection Institute in 1979 with the “Guichao 2” as the female parent, “I R2061-404-2-4-5” as the father of the hybrid throughout the year Pujiang bed nursery earlier strain Department of identification options, stable in 1984. Rice blast pandemic in 1985, the province’s regional trials show that this species not only retains the Gui Chao 2 high yield performance, but also integrated into the “IR2061-461-2-4-5” disease resistance and good quality And other fine traits, is medium maturing varieties. The province’s two-year regional experiment average yield of 498 kg per mu, the maximum output of 574.9 kg, and the control of Shanghai Branch No. 3 quite. The resistance to blast is strong, and the potential for planting in the ward has a great potential for yield increase. In the blast area of Sichuan Province, the yield of Chuanxi film increased by 12.4% compared with the control. Chuanzhi No. 3 leaf color lighter, straight leaf posture, narrow legislation, plant type loose moderate, with pest-resistant characteristics. In shallow mountains, hilly areas have a blasting epidemic inhibitory effect. In 1959 through the Sichuan Provincial Variety Approval Committee validation.
