2003～2004年分别从合肥丰乐种业股份有限公司引进国丰1号、丰两优1号、丰两优香1号、丰优205等4个杂交水稻新组合,在古田县进行试验示范。经反复多点试验种植表明,除国丰1号表现生育期偏短,易感穗颈瘟,不宜在古田县推广使用外,其余3个组合均表现高产、抗病、生育期适中,有望引进推广使用,特别是丰两优1号再生能力较强,不但可以作为中稻栽培还可以进一步探讨作为再生稻种植。
From 2003 to 2004, Hefei Fengle Seed Industry Co., Ltd. introduced four new hybrid rice combinations, Guo Feng 1, Feng Liang You 1, Feng Liang You Yu 1 and Feng You 205, respectively, in Gutian County . The results of repeated multi-point experiments showed that except for Guofeng 1 which had short growth period and susceptible panicle blast, it should not be used widely in Gutian County. The other three combinations showed high yield, disease resistance and moderate growth period and were expected to be introduced Popularization and use, especially the strong reproductive capacity of Fengliangyou 1, can not only be used as a medium-sized rice cultivation but also further explored as a regenerative rice planting.
