全椒县水稻适应性品种筛选

Screening of Rice Adaptive Varieties in Quanjiao County

分别以5种籼稻品种、5种粳稻品种为试验材料,在安徽省全椒县进行水稻适应性品种筛选试验。结果表明,粳稻品种生育期普遍高于籼稻,粳稻品种中Ⅲ优98生育期最短,为148 d,籼稻中苏秀867生育期最短,为131 d,镇稻15生育期最长,可能影响到下茬作物播种和生长;甬优1109株高最高,为134 cm,武运粳32株高最低,为93 cm;南粳5055有效穗数最高,达到了360.0万穗/hm^(2);荣两优华占每穗粒数最多,为276.1个;开两优17千粒重最高,为29.0 g;粳稻品种镇稻15产量最高,为8311.5 kg/hm^(2),籼稻品种开优17产量最高,为7900.5 kg/hm^(2)。粳稻品种武运粳32、南粳5055和籼稻品种C两优华占、开两优17整体表现较好,是适合全椒县种植的品种,建议加大推广面积。

A total of 5 Indica varieties and 5 Japonica varieties were used as experimental materials to test the adaptability of rice varieties in Quanjiao County of Anhui Province.Results showed that the growth period of Japonica rice was generally higher than that of Indica rice.The growth period of Japonica rice varietyⅢyou98 was the shortest(148 d),Indica rice Suxiu 867 was the shortest(131 d),and Zhendao 15 was the longest,which might affect the sowing and growth of next crop.Yongyou 1109 had the highest plant height of 134 cm,and Wuyunjing 32 had the lowest plant height of 93 cm.Effective ears of Nanjing 5055 was the highest,reaching 360.0×104/hm^(2);Rongliangyouhua had the largest grains per ear(276.1 grains).Kailiangyou 17 had the highest 1000-grain weight(29.0 g).The yield of Japonica rice variety Zhendao 15 was the highest(8311.5 kg/hm^(2)),and that of Indica rice variety Kaiyou 17 was the highest(7900.5 kg/hm^(2)).Japonica rice varieties Wuyunjing 32 and Nanjing 5055,as well as Indica rice varieties C liangyouhuazhan and Kailiangyou 17,performed well as a whole,which were suitable for planting in Quanjiao County and were suggested to increase the promotion area.
