摘　　要：为了筛选出适宜永州地区推广种植的高产、优质中稻品种,选用近年来选育并在湖南省大面积推广的优良中稻品种,在永州地区开展了中稻新品种适应性及高产特性田间比较试验。通过对不同品种的生育期、农艺性状、产量与产量构成以及病虫害抗性进行对比分析,筛选出了4个丰产性好、生育期适中、综合性状表现较优的品种适宜在永州地区推广种植,其中,隆晶优1195的产量最高,达739.16 kg/667m~2,比晶两优华占(CK)增产7.89%,全生育期128 d;隆晶优蒂占的产量第二,为728.00 kg/667m~2,比CK增产6.26%,全生期126 d;玮两优1206的产量第三,为714.16 kg/667m~2,比CK增产4.24%,全生育期130 d;晶两优蒂占的产量与CK相当,为684.74 kg/667m~2,全生育期132。In order to screen out high-yield,high-quality mid-season rice varieties suitable for planting and promotion in Yongzhou area,nine new mid-season varieties of national second-class high-quality were used as materials to carry out field adaptability and high-yield demonstration comparison test in Lingling District of Yongzhou.By comparing and analyzing the characteristics of growth duration,agronomic traits,yield,yield composition and pest resistance,four varieties with high fertility,moderate growth duration and good comprehensive traits were screen out;among them,Longjingyou 1195,with a 128 d whole growth duration,yielded the highest,up to 11,087.4 kg/hm~2,7.89% higher than JingliangyouHuazhan(CK);LongjingyouDizhan ranked the second by a yield of 10,920.0 kg/hm~2,6.26% higher than CK,whose whole growth duration was 126 d;Weiliangyou 1206,with a whole growth duration of 130 d,yielded 10,712.4 kg/hm~2,ranking the third and surpassing CK by 4.24%;underwent a 132 d whole growth duration,JingliangyouDizhan yielded 10,271.1 kg/hm~2,similar to CK.
