【摘要】 分析了2020年通过省级以上审定的适宜湖北生态区(武陵山区除外)作一季中稻种植的荃优系列优质水稻品种的基本特性。结果表明,适宜优质水稻品种共12个,从品种选育主体来看,以企业参与选育的品种为主;荃优系列优质杂交组合品种普遍穗大粒多、结实率较高,但有效穗数一般,在单位产量中以单穗产量贡献较大;荃优系列优质杂交组合可以选配出米质优良、抗稻瘟病的品种,但选育抗白叶枯病、抗褐飞虱的品种还有待加强。更多还原

【Abstract】 Abstact:In this paper,the basic characteristics of Quanyou series of high-quality rice varieties,which were suitable for planting in Hubei ecological areas(except Wuling Mountain Area)and approved by the provincial government in 2020,were analyzed. The rueslt showed that,there were 12 suitable rice varieties. Viewing from the main body of variety breeding,the varieties mainly selected by enterprises;Quanyou series of high quality hybrid combinations generally had large grains per panicle and high seed setting rate,but the effective panicle number was general,and the yield per panicle contributed more in unit yield. Quanyou series of high quality hybrid combinations could be selected and bred varieties with good rice quality and blast resistance,but breeding varieties resistant to bacterial blight and brown planthopper remained to be strengthened.更多还原
