摘要
探讨中国玉米(Zea mays L.)品种在缅甸的适应性和产量表现,筛选适宜当地种植的品种。2020年秋在缅甸南部的内比都市采用随机区组设计,以当地品种C.P621为对照,对中国16个玉米品种的物候期、产量、产量构成要素及抗病性等进行鉴定与评价。结果表明,16个品种在生育进程、植株性状、果穗性状、抗病虫害等方面均优于对照C.P621,其中鸿单670、A302、A303和惠玉3226在穗长、穗粗、穗行数、行粒数、出子率和秃尖方面均优于对照;除99ⅹ罗父和丰玉981对纹枯病和穗腐病的抗性稍差外,其余品种均对当地的病虫害有很好的抗性;在产量表现方面有11个品种的产量比对照高,占参试品种的68.75%,其中鸿单670、A303和惠玉3226的产量达9000.00 kg/hm^(2)以上,分别比对照增产20.70%、18.49%和17.20%。综合各项调查鉴定结果,鸿单670、A303、惠玉3226、高亢718、A301、金玉8号、万禾1821、兆丰588、V1806、丰玉981、A302株型适中、产量高、抗性好,对缅甸南部气候具有很好的适应性,适宜在缅甸南部地区推广与应用。
The adaptability and yield performance of Chinese maize(Zea mays L.)varieties in Myanmar were studied to screen suit⁃able varieties for local planting.In the autumn of 2020,the randomized block design was adopted in Nairobi City in southern Myan⁃mar,and the phenology,yield,yield components and disease resistance of 16 maize varieties in China were identified and evaluated with the local variety C.P621 as the control.The results showed that the 16 varieties were better than the control C.P621 in the growth process,plant traits,ear traits,pest resistance and other aspects.Among them,Hongdan 670,A302,A303 and Huiyu 3226 were better than the control in ear length,ear diameter,ear rows,grains per row,seed rate and bald tip.Except that the resistances of 99 x Luofu and Fengyu 981 to sheath blight and ear rot were slightly poor,their varieties had good resistance to local pests and diseases.In terms of yield performance,the yields of 11 varieties were higher than those of the control,accounting for 68.75%of the tested variet⁃ies.The yields of Hongdan 670,A303 and Huiyu 3226 reached above 9000.00 kg/hm^(2),which were 20.70%,18.49%and 17.20%higher than those of the control,respectively.Based on the investigation and identification results,Hongdan 670,A303,Huiyu 3226,Gaokang 718,A301,Jinyu 8,Wanhe 1821,Zhaofeng 588,V1806,Fengyu 981 and A302 had moderate plant types,high yield and good resistance.They had good adaptability to the climate in southern Myanmar and were suitable for promotion and applica⁃tion in southern Myanmar.
