摘要: 为筛选适合广西都安瑶族自治县种植的粮饲兼用型玉米(Zea mays L.)新品种,对12个玉米新品种的农艺性状、产量和品质指标进行测定,分析各项指标间的相关性,采用隶属函数法对参试品种进行评价。结果表明,子粒产量和全株生物产量最高的为桂单671,分别为10 908 kg/hm2和49 965 kg/hm2;其次为兆玉215,分别为10 086 kg/hm2和47 175 kg/hm2。子粒产量与穗粗和百粒重呈极显著正相关(P<0.01),与全株生物产量、淀粉含量、穗长和行粒数呈显著相关(P<0.05);全株生物产量与行粒数呈极显著相关(P<0.01),与淀粉含量、穗长、株高和穗位高呈显著相关(P<0.05)。参试品种综合表现得分由高到低依次为桂单671、兆玉215、桂单669、桂单6208、桂单666、桂单6205、桂单660、桂单6203、桂单6206、桂单162、桂单668、桂单673。根据隶属函数值并结合各项指标判断,桂单671和兆玉215综合表现较好,可作为都安瑶族自治县及其周边地区首选粮饲兼用型玉米品种进行推广种植。

Abstract: To screen new maize(Zea mays L.) varieties suitable for food and fodder dual-purpose in Du'an Yao Autonomous County of Guangxi, the agronomic characters, yield and quality indexes of 12 new maize varieties were measured, the correlation between various indexes were analyzed, and the comprehensive performance of the tested varieties were evaluated by membership function method. The results showed that the variety with the highest grain yield and whole plant biomass was Guidan 671, which were 10 908 kg/hm2 and 49 965 kg/hm2 respectively; the second was Zhaoyu 215, which were 10 086 kg/hm2 and 47 175 kg/hm2 respectively. Grain yield was highly significantly positively correlated with ear diameter and 100 grain weight(P<0.01), and significantly correlated with whole plant biomass, starch content, ear length and grain number per row(P<0.05); the whole plant biomass was highly significantly correlated with the number of grains per row(P<0.01), and significantly correlated with starch content, panicle length, plant height and panicle height(P<0.05). The comprehensive performance scores of the tested varieties from high to low were Guidan 671, Zhaoyu 215, Guidan 669, Guidan 6208, Guidan 666, Guidan 6205, Guidan 660, Guidan 6203, Guidan 6206, Guidan 162, Guidan 668 and Guidan 673. According to the values of membership function and combined with various indexes, Guidan 671 and Zhaoyu 215 had good comprehensive performance, and could be used as the first choice for food and fodder dual-purpose maize varieties in Du'an Yao Autonomous County.

Key words: maize(Zea mays L.), food and fodder dual-purpose, membership function method, comprehensive evaluation
