强再生力杂交稻品种筛选及其农艺性状表现

Selection of Strong Regenerative Hybrid Rice Varieties and Their Agronomic Traits Performance

再生稻是中国南方稻区提高复种指数和增加粮食产量的一项重要种植模式,品种再生力强与弱及其农艺性状优与劣是决定再生稻发展成败的重要因素。2022年选用6个优质稻新品种为供试材料,以泸优明占为对照,研究调查了人工收割高留桩条件下各品种再生力及头季和再生季的农艺性状。结果表明,榕夏两优676、荃优607、内10优7185等3个品种具有再生力强、产量高的特点,适宜在尤溪县再生稻区大面积推广。

Regenerated rice was an important planting mode for improving the multiple cropping index and increasing grain yield in southern China’s rice regions.The strong or weak regeneration ability of varieties and the excellent or poor agronomic traits were important factors determining the success or failure of the development of regenerated rice.In 2022,six good quality new rice varieties were selected as the test materials,with Luyoumingzhan as the control.The study investigated the regeneration ability and agronomic traits of each variety under the conditions of artificial harvesting with high retention piles.The results showed that three varieties,Rongxialiangyou 676,Quanyou 607 and Nei 10 You 7185,had strong regeneration ability and high yield,and were suitable for large-scale promotion in Youxi County’s ratooning rice area.
