2011年引进9个中稻—再生稻新组合进行对比试验,以Ⅱ优沈98为对照,从产量、穗粒结构、抗逆性等性状进行对比,结果表明：Ⅱ优3301、Ⅱ优沈98、嘉糯I优6号等组合,不但头季稻表现突出,再生季的再生率、产量也表现较优,较适宜长汀县推广;谷优3301、宜优99、宜优673因生育期较短,宜作搭配品种推广;其余需再试种考查。
2011年引進9箇中稻—再生稻新組閤進行對比試驗,以Ⅱ優瀋98為對照,從產量、穗粒結構、抗逆性等性狀進行對比,結果錶明：Ⅱ優3301、Ⅱ優瀋98、嘉糯I優6號等組閤,不但頭季稻錶現突齣,再生季的再生率、產量也錶現較優,較適宜長汀縣推廣;穀優3301、宜優99、宜優673因生育期較短,宜作搭配品種推廣;其餘需再試種攷查。
2011년인진9개중도—재생도신조합진행대비시험,이Ⅱ우침98위대조,종산량、수립결구、항역성등성상진행대비,결과표명：Ⅱ우3301、Ⅱ우침98、가나I우6호등조합,불단두계도표현돌출,재생계적재생솔、산량야표현교우,교괄의장정현추엄;곡우3301、의우99、의우673인생육기교단,의작탑배품충추엄;기여수재시충고사。
Nine new combinations of semilate rice and ratoon rice were introduced and comparative tests were carried out in 2011.The characters including yield,panicle-spikelet structure,stress resistance and so on were compared with II Youshen 98 as control.The result showed that the combinations of II You 3301,II Youshen 98,Jianu I You No.6 not only performed prominently in main cropping season,but also showed better in regeneration rate and yield in ratoon rice season.They were suitable to be extended in Changting county.The growth period of Guyou 3301,Yiyou 99 and Yiyou 673 was shorter,and they were used suitably as auxiliary cultivars.Trial planting needed to be conducted in another combination.
