摘  要:
[目的]鉴定杂交中籼稻新品种的丰产性、适应性和综合抗性,为江淮稻区推广主导品种提高科学依据。[方法]采用方差分析及最小显著极差法对比研究11个中籼稻新品种(Ⅱ优838、两优383、荃优822、新两优223、协优107、Ⅱ优024、徽两优348、丰两优80、开优8号、冈优1577、金优R源5)。[结果]参试品种全生育期皆在适宜范围内;较对照Ⅱ优838增产的有6个品种,较对照减产的有4个品种,各品种较对照产量呈极显著差异。[结论]筛选出适合江淮稻区乃至周边地区种植的高产、多抗、优质的杂交稻新品种徽两优348、新两优223、荃优822、两优383、Ⅱ优024等。

摘  要:
[Objective] To identify the adaptability,yielding ability and comprehensive resistance of new varieties of Indica hybrid rice,and to provide scientific basis for the dominant species extension in Jianghuai rice region. [Method] A total of 11 new varieties of indica hybrid rice were compared by variance analysis and least significant ranges( LSR-SSR). [Result]The whole growth stages of tested varieties were all within the suitable range. Compared with the control ⅡYou 838,six varieties showed increase in yields,and four varieties decreased. All the varieties showed extremely significant differences with the control. [Conclusion] High-yield new varieties of Indica rice suitable for Jianghuai rice region and its surrounding areas are screened,which are Huiliangyou 348,Xinliangyou 223,Quanyou 822,Liangyou 383,Ⅱ You 024 and so on.
