Primary report to new combination of semilate rice and ratoon rice
Abstract：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.
