| 摘 要： | 本文研究了我校近两年选育的7个早杂新组合在我省作早稻栽培的可能性及应用价值。威优242—2比威优49早4～5d,单产与威优49相近,日产量比威优49高,稻米品质优良,中抗稻瘟病和白叶枯病,可望在我省作中熟早稻栽培。汕优242—2比威优49早3d,产量比威优49略高,且成熟时落色好;对稻瘟病的抗性明显优于威优49,稻米品质优良,可在我省作中迟熟早稻种植。

| Abstract: | The possibility and use value are studied as to seven new recombinations of the hybrid rice breeded in Hubei University as early rice in Hubei Province.
Wei -You 2-12 is 5-6 days earlier in the prowth period duration, and higher in the yield per day than Wei -You 49. It can be plantted tentatively as a middle - season recombination of early rice in Huberi.
The prowth period duration of Shan -You 242 is 2 days earlier than that of Wei - You 49, so Shan -You 242 can be used as a middle -late recombination of early rice in Hubei. |
