Aluminum(Al) toxicity is a major abiotic stress limiting crop yield in acidic soil. Al toxicity inhibits plant root growth and development, leading to insufficient uptake of water and nutrient from soil. Soybean is sensitive to Al toxicity, exhibiting impaired root growth under elevated Al concentrations. In this research, two soybean lines(Magellan and PI 567731) were identified to differ in Al tolerance represented by primary root length ratio(PRLatio), total root length ratio(TRLatio), and root tip number ratio(RTNatio) under 25 μM Al3+. The recombinant inbred line(RIL) population derived from the cross of these two lines exhibited high inheritance(0.65 to 0.85) in Al tolerance-related traits. The quantitative trait loci(QTL) mapping identified three QTL on chromosome(Chr.) 3, 13 and 20 associated with Al tolerancerelated traits. qAlm20 explained the largest phenotypic variation of ～ 27.4% and mainly played roles in maintaining root elongation. qAlm03 and q Alm13 were mapped as novel Al tolerance loci and predicted to be mainly involved in maintaining root tip initiation or root elongation under Al stress, respectively. Furthermore, the two major QTL(qAlm13 and qALm20) were confirmed using nearisogenic lines(NILs), and they seemed to regulate Al tolerance in tissue tolerance pathway instead of Al3+ exclusion or transport. The tolerant allele of qALm20 was identified as a rare allele, which has not been widely utilized in soybean breeding. Our results not only provided novel genetic resources for breeding Al tolerant soybean varieties, but also confirmed Al tolerance QTL in the NIL background and proposed the possible mechanisms underlying them.

第24届全国大豆科研生产研讨会

作者：矫永庆周新安油清波郭葳 tri vuong Henry Nguyen 中国农业科学院油料作物研究所美国密苏里大学哥伦比亚分校国家大豆生物技术中心

大豆孢囊线虫(Soybean Cyst Nematode,Heterodera glycinesIchinohe)、南方根结线虫[Southern Root Knot Nematode,Meloidogyne incognita(Kofoid and White)Chitwood]和肾形线虫(Reniform Nematode,Rotylenchulus reniformis Linford and Oliveira)是危害大豆的三种主要线虫。相对于杀虫剂和轮作技术而言,种植抗性品种是防治这种病害的最经济、环保和有效的手段之一。抗性基因的QTL定位与分子标记辅助育种相结合,是开发抗性品种的一种快捷有效的手段。对于大豆孢囊线虫而言,当前生产应用的抗源主要是PI88788、PI209332、PI437654以及Peking。尽管已经约有23个抗孢囊线虫的QTL被定位,但生产上应用的抗性基因主要还是Rhg1和Rhg4。Rhg1和Rhg4主要提供大豆孢囊线虫生理小种3(HG type 0)的抗性。长期的应用这2个抗性基因,已经造成大豆孢囊线虫的生理小种发生漂移,从而导致Rhg1和Rhg4抗性的逐渐丧失。大豆根结线虫、肾形线虫的研究比较少。到目前为止,只有3个抗根结线虫和2个抗肾形线虫的QTL被鉴定。大豆线虫抗性资源狭窄已经引起育种学家的关注。发掘新的抗性种质并鉴定新的抗性基因,同时将大豆已有的抗线虫QTL聚合,既增强抗性程度又提供广谱性抗性,这是未来大豆抗线虫研究的一个重要的方面。我们评价了650份大豆种质资源(MGⅢ-Ⅴ)对7种孢囊线虫生理小种即SCN HG type2.5.7(PAl),1.***.5.7(PA 2),0(PA 3),2.5.7(PA5),1.***.5.6.7(PA 14),1.***.3.4.5.6.7(LY1)and1.***.3.4.5.6.7(LY2)的抗性。总共获得了对大豆孢囊线虫高抗(FI<10)或中抗(10

Modeling water resources under competing demands for sustainable development: A case study of Kaligandaki Gorge Hydropower Project in Nepal

引用

Water Science and Engineering 2019年第1期12卷 19-26页

作者： Rakesh Sahukhal tri Ratna Bajracharya Energy Environment Research and Development CentreLalitpur 44602Nepal Institute of Engineering Department of Mechanical EngineeringTribhuwan UniversityLalitpur 44600Nepal

The challenges posed by climate change require that the quantity and quality of water resources in Nepal be managed with sustainable development practices. The communities around the Kaligandaki Gorge Hydropower Project in the Myagdi District of Nepal depend on river flow for most of their rural and agricultural needs. Without a sustainable development plan, the growing population of the region, confined in an area with declining water resources, will face serious challenges to economic growth. Meteorological data show increasing annual average rainfall at a slight rate of about 0.284 mm/year, with erratic annual percentage change in rainfall in the area. The mean and minimum temperatures show decreasing trends at the rates of 0.05-C and 0.14-C per year, respectively. An assessment of the impacts on water availability for domestic and irrigation usage in the face of competing demands caused by the hydropower development project in the Kaligandaki Gorge was undertaken. The water demand and supply modeling were conducted using the water evaluation and planning (WEAP) model, based on discharge data from the Kaligandaki River, which were obtained from the Department of Hydrology and Meteorology, Nepal. The available data from 2001 to 2003 were used to estimate the model parameters while the stability of these parameters was tested with a validation period from 2004 to 2007. The performance of the model was assessed through statistical measures of calibration with the root mean square error and coefficient of determination, whose values were 0.046% and 0.79, respectively. Two scenarios were created in addition to the base case scenario: the discharge decrement scenario and new irrigation technology scenario. Analysis showed that a prioritization of demands will be necessary in the area in the near future for the purpose of sustainability of water resources, due to climate change impacts.
