摘　　要：2018年黔东南州农业科学院引进7个杂交水稻新品种,进行大田生产试验,综合评价各品种在黄平县种植的丰产性、稳产性、适应性,以期筛选出适宜在当地种植的水稻新品种。结果表明:各参试品种单产均高于F优498(ck),其中恒丰优426、陵优2749分别比对照增产13.99%、10.74%,生育期适中,株型紧凑,综合表现好,建议在本区域内大面积推广;金优321比对照增产14.31%,株型紧凑,综合表现好,缺点是生育期偏长,可在700~800m海拔区域推广;宜香2239、泸优578分别比对照F优498增产8.89%、6.12%,两者生育期偏长,株型好,可在下一年继续种植,进一步观察;扬优香占、Y两优粤禾丝苗分别比对照增产2.33%、1.08%,增产效果不明显,且两者生育期偏长,株型较差,不建议示范推广。In 2018,Qiandongnan academy of agricultural sciences introduced seven new hybrid rice varieties and conducted field production tests with Fyou 498 as the contrast.Evaluating comprehensively the high yield,stable yield and adaptability of the hybrid rice varieties planted in Huangping County.New rice varieties suitable for local cultivation were screened out and provided theoretical basis for large area popularization.The results showed that the yield per unit area of the tested varieties were higher than that of Fyou 498(ck).Among them,Hengfengyou 426 and Lingyou 2749 increased 13.99%and 10.74%respectively compared with the Fyou 498.Both of them growth period were moderate,the plant type were compact and the comprehensive performance were good.It was suggested that Hengfengyou 426 and Lingyou 2749 should be popularized in large area.Compared with the Fyou 498,the yield of Jinyou 321 increased 14.31%,the plant type was compact and the comprehensive performance was good,Its disadvantage was that the growth period was longer,it could be planted at 700~800 m altitude.Compared with the Fyou 498,Yixiang 2239 and Luyou 578 increased their yields by 8.89%and 6.12%respectively.Both of them had longer growth period and better plant type,they could be planted in the next year for further observation.Yangyou Xiangzhan and Y Liangyou Yuehe Simiao seedlings were 2.33%and 1.08%higher than those of Fyou 498 respectively,but the effect of increasing yields was not obvious,and the growth period of the two seedlings were longer and the plant type was badder,not demonstration promotion is recommended.
