摘要
以2010～2012年示范和展示品种为材料,以各品种单位面积平均产量及其株高、有效穗数、每穗粒数、结实率、千粒重、穗长等6个产量性状的表型值为依据,通过三年平均产量比较试验,系统的阐述了不同熟期品种在二积温带的产量及产量性状表现。试验结果表明:与主栽品种空育131比较,2010～2012年平均产量较高的11片叶品种为龙粳29、垦粳2号、垦稻21、垦稻20、龙粳27、龙粳20、龙粳26;产量较稳定的品种为空育131、龙粳25、龙粳20、垦粳2号、龙粳29。12片叶品种年际间产量差异较显著,相对较稳定的品种为垦鉴稻6号、垦稻14、龙粳21,绥粳10、松粳10、北稻5号;与主栽品种垦稻12比较,三年平均产量较高的品种为垦粳4号、垦稻14、垦鉴稻6号、绥粳10、龙粳21。本地区适宜选择11片叶品种为主栽品种。
The experiment of yield comparisons of rice varieties were conducted in 2010-2012 according to plant height, effec- tive panicle umber, grain number per panicle, seed setting rate,1000-grain weight and panicle length for explaining expression of rice varieties with different growth period in second accumulated temperature zone. The results showed that compared with Kongyu131, high-yield varieties containing 11 leaves were Longjing29, Kenjing2, Kendao21, Kendao20, Longjing27, Longjing20, and Longjing26, stable-yield varieties were Kongyul31, Longjing25, Longjing25, Longjing20, Kenjing2 and longjing29. Yield differences were significant in rice varieties containing 12 leaves between years and stable-yield varieties were Kenjiandao6, Kendao14, Longjing21, Suijin10, Songjing10 and Beidao5. Compared with Kendao12, high mean yield included Kenjing4, Kengdao14, Kenjiandao6, Suijing10 and Longjing21. rice varieties containing 11 leaves were suitable for production in this area.
