中文摘要	【目的】内蒙古自治区是中国大豆品种生态类型最为丰富的省份之一,研究内蒙古自治区大豆品种生育期多样性及分布规律,不仅是该区品种合理布局及区内外种质交流的迫切需要,而且可为全国大豆生育期分组和基于生育期组的大豆种植区划提供参考。【方法】以分属MG000、MG00、MG0、MGⅠ、MGⅡ和MGⅢ的21个北美大豆生育期组标准品种为对照,在扎兰屯、赤峰、呼和浩特、杭锦后旗和额济纳旗等5个地点,对从内蒙古自治区各地生产上收集的120个代表性大豆品种进行田间种植,每个品种选整齐一致的15个植株定点观察,分株记载播种期、出苗期(VE)、始花期(R1)、生理成熟期(R7)和完熟期(R8),初霜时记载未成熟材料的最终发育时期。以出苗至生理成熟期(VER7)日数作为判定生育期的依据,应用分年度划分法对供试品种进行生育期组划分。同时,对代表性品种做地理分布调查,明确其在内蒙古自治区分布的最北界限。【结果】供试内蒙古大豆品种归属于MG0000MGⅢ这7个生育期组,其中3个早于MG000划分下限1.07.4 d,将其归入到MG0000,6个属MG000、20个属MG00、43个属MG0、35个属MGⅠ、8个属MGⅡ、5个属MGⅢ。MG0000分布于大兴安岭东北麓及呼伦贝尔高原东北部地区;MG000分布于大兴安岭东麓近山地区、呼伦贝尔高原的西部及阴山南北高寒地区;MG00分布于呼伦贝尔市大兴安岭以东较冷凉地区、阴山前后冷凉地区局部和阴山东段大兴安岭南部冷凉地区;MG0分布于大兴安岭以东嫩江流域的呼伦贝尔、兴安盟传统农区及通辽市、赤峰市北部山区及阴山山脉前山较暖地区;MGⅠ分布于大兴安岭东南温凉区、赤峰丘陵山地温凉区及阴山南麓温凉区;MGⅡ分布于大兴安岭岭南温和区、阴山南麓土默川平原和河套梁外温和区;MGⅢ分布于西辽河平原温热区、大青山南部梁峁地、河套平原灌溉区和阿拉善高原绿洲地区。根据品种分布区域,参照当地农业区划和气象资料,形成了基于品种生育期组的内蒙古自治区大豆种植区划方案,绘制了各生育期组品种的种植区划图。在以上工作基础上,提出了内蒙古自治区大豆品种引种方案和区域试验分区调整方案。【结论】内蒙古自治区大豆分布区域广,生育期生态类型丰富。通过生育期分组,可优化品种布局,加强区内外种质交流,提高品种选育和推广的针对性,加速品种的推广利用。
英文摘要	【Objective】The Inner Mongolia Autonomous Region is one of the areas with the most abundant soybean ecological types in China. Understanding the diversity and distribution of the soybean varieties according to their maturity groups (MGs) in the region is not only of great importance for rational distribution and exchange of the germplasm, but also providing a model for soybean varietal maturity group classification and planting regionalization of the country. 【Method】To classify soybean varieties from the region into different maturity groups, 21 standard varieties which represent MG000, MG00, MG0, MGⅠ, MGⅡ and MGⅢ of soybean were introduced from North America as references in this study. In the field tests, 120 local varieties collected from the major soybean producing areas were planted in Zhalantun, Chifeng, Hohhot, Hangjin Rear Banner and Ejin Banner together with the MG reference varieties. Fifteen plants with the similar growing tendency were observed, and the dates of VE (emergence), R1 (beginning bloom), R7 (beginning maturity) and R8 (full maturity) were recorded. The method of "Classifying MG by Individual Years" was used for maturity group classification of the varieties. Geographical distribution and the north boundary of the representative varieties in the Inner Mongolia Autonomous Region were surveyed. 【Result】Varieties from the Inner Mongolia Autonomous Region were classified into 7 MGs of MG0000, MG000, MG00, MG0, MGⅠ, MGⅡ and MGⅢ. Three varieties matured earlier than MG000 were classified into MG0000, and 6, 20, 43, 35, 8, and 5 varieties were respectively classified into MG000, MG00, MG0, MGⅠ, MGⅡ and MGⅢ. The MG0000 varieties were mainly distributed in the northeast foothill area of Daxinganling Mountains and northeast section of Hulun Buir Plateau. The MG000 varieties were distributed in the east foothill area of Daxinganling Mountains. The MG000 varieties were distributed in west section of Hulunbuir plateau and the south and north alpine areas of Yinshan Mountains. The MG00 varieties were distributed in cool area of Yinshan Mountains and east and south section of Daxinganling Mountains. The MG0 varieties were distributed in Hulunbuir and Xingan League traditional agricultural regions in the Nen River valley at the eastern Daxinganling Mountains, Tongliao city, the mountainous area of north Chifeng and the warm areas of the Yinshan Mountains outer hill. The MGⅠvarieties were distributed in the cool-warm area of southeast section of Daxinganling Mountains, Chifeng hilly mountains and south foothill area of the Yinshan Mountains. The MG Ⅱ varieties were distributed in mild area of the south section of Daxinganling Mountains, Tumochuan Plain at south foothill area of Yinshan Mountains and Liangwai region of the Hetao Plain. The MG Ⅲ varieties were distributed in West Liaohe Plain warm area, Daqing Mountain gully slope area,Hetao Plain irrigated area and Alxa Plateau oasis area. According to the MGs and planting area of the test varieties and referring to the agricultural regionalization and meteorological data, soybean planting regionalization of the Inner Mongolia Autonomous Region was proposed, and soybean MG geographical distribution map in the Inner Mongolia Autonomous Region was drafted. In addition, the variety introducing scheme in the Inner Mongolia Autonomous Region and eco-regional adjustment plan for the uniform tests were proposed. 【Conclusion】Soybean varieties in Inner Mongolia were distributed widely in geological regions and diverse in MGs and ecological types. The MG classification could optimize the distribution, strengthen the exchange of soybean germplasm within and out of the region, highlight the targets of soybean breeding and extension, and accelerate the broad utilization of the varieties.
