杂交水稻新品种在霍山试种表现

目的]筛选适宜霍山地区种植的杂交水稻新品种,促进杂交水稻的进一步发展,提高稻谷产量,增加农民收入。方法]以目前推广面积较大的品种(徽两优898、丰两优4号、新两优6号、丰两优9号、皖稻153、Y两优1号、深两优5814)为参试品种,以Ⅱ优838为对照。结果]徽两优898无论是在产量还是在抗性上都明显优于对照。徽两优898产量最高为10 938.3 kg/hm2;全生育期与对照最接近,比对照早7 d;株高只有124 cm,穴有效穗较多达到11.5个,结实率最高达到86.7%;对稻瘟病表现出较强的抗性。结论]徽两优898生育期适中,综合性状优异,可为霍山地区水稻高产优质生产提供品种支撑。

Study of Plant Experiment of New Hybrid Rice Cultivars in Huoshan

Objective ] The aim was to screen out the suitable hybrid rice eultivars for planting in Huoshan Area, to promote its development further, improve rice yield, and increase farmer＇s income. Method] The eultivars with bigger promotion area at present, Huiliangyou 898, Fengliangyou No. 4, Xinliangyou No. 6, Fengliangyou No. 9, Wandao 153, Y liangyou No. 1 and Shengliangyou 5814, were taken as the experimental euhivars, and Ⅱ You 838 as control. Result] Huilaingyou 898 significantly exceeded to control not only in yield but also in resistance. Huiliangyou 898＇ s yield was the highest by 10 938.3 kg/hm^2 ; its total growth period was close to that of control, and 7 days earlier that that of control ; its plant height was only 124 em, its effective ear per hole was more and up to 11.5, its setting rate was the highest and up to 86.7% ; its had strong resistance to rice blast. Conclusion] Huiliangyou 898 had characteristics of moderate growth period and good comprehensive traits, provides a euhivar support for rice high yield and good quality production in Huoshan Area.
