摘要: 【目的】筛选出适宜内蒙古中西部种植的优良大豆新品种,为今后该地区大豆育种提供理论依据。【方法】 对北方春大豆中熟组区域试验的10个大豆新品种(系)的农艺性状和产量指标进行比较与相关性分析。【结果】 各品种生育日数为118~126 d,均属北方春大豆中熟组品种;产量变化规律为中吉602>赤豆201>东农豆251>吉育491>吉农28>吉育306>吉育481>吉育86>龙黄1503>吉育494,其中,中吉602产量最高,为3 440 kg/hm2,比对照增产10.9%,增产极显著(P<0.01),其单株荚数也极显著高于其他品种(P<0.01);产量与单株粒重呈极显著正相关(P<0.01),与单株荚数、单株粒数、百粒重呈显著正相关(P<0.05),单株粒数与单株荚数、单株粒重、百粒重、产量均呈显著正相关(P<0.05)。【结论】 内蒙古中西部区适宜种植株高适中、单株生产力强、单株荚数和粒数多且百粒重相对较大的大豆品种,中吉602、吉育491和赤豆201综合性状突出,可进一步在该地区试验种植。

Abstract: 【Objective】In order to select excellent soybean varieties suitable for planting in the central and western regions of Inner Mongolia,and provide a theoretical basis for soybean breeding in the future. 【Methods】In this experiment,ten new soybean varieties (lines) were collected from different regions,and their agronomic characteristics and yield indexes were compared and analyzed. 【Results】The results showed that the growth period of each variety was between 118-126 days,which belong to the north spring soybean medium ripe group variety and the yield change rule was:Zhongji 602>Chidou 201>Dongnongdou 251>Jiyu 491>Jinong 28>Jiyu 306>Jiyu 481>Jiyu 86>Longhuang 1503>Jiyu 494. Zhongji 602 had the highest yield of 3 440 kg/hm2,which was 10.9% higher than that of the control(P<0.01). The yield was significantly positive-correlated with the grain weight per plant(P<0.01),and positive-correlated with the number of pods per plant,the number of seeds per plant,and the 100-grain weight per plant(P<0.05);the number of seeds per plant was positive-correlated with the number of pods per plant,the grain weight per plant,the 100-grain weight per plant,and the yield(P<0.05). 【Conclusion】The central and western regions of Inner Mongolia were suitable for soybean varieties with moderate planting height,high productivity per plant,many pods and seeds per plant,and larger 100-grain weight. Zhongji 602,Jiyu 491,and Chidou 201 have outstanding comprehensive characteristics,which can be further planted in this area.
