摘要

背景:班巴拉花生具有抗旱能力和较高的营养价值,是豆科作物中尚待开发的一个值得重视的问题。因此,本研究将着眼于PEG浓度引起的渗透胁迫与抗旱性之间的关系,以获得具有抗旱性的基因型。方法:实验于2019年1 - 3月在印度尼西亚玛琅布拉维贾亚大学农学院农学系组织培养实验室进行。采用聚乙二醇(PEG) 6000对30个不同基因型的班bara花生进行了不同浓度(0%、5%和10%)的抗旱性评价。试验采用完全随机设计,设3个重复。结果:10%聚乙二醇是选育班芭拉花生耐旱性品系的最适宜浓度。基因型对PEG浓度有不同的反应。在易感品系中,萌发受到阻碍和延迟,形成下胚轴长度、根长、鲜重和干物质等限制,而耐旱品系则能正常萌发。获得6个耐旱品系,5个本地品系,分别为BBL 1.1、PWBG 5.2.1、PWBG 6、SS 2.4.2、SS 3.4.2, 1个泰国品系为Tvsu 86。

Evaluation of Some Morphological Criteria to Drought Tolerance on Seedling of Bambara Groundnut [Vigna subterranea (L.) Verdc.] using Polyethylene Glycol (PEG6000)
Background: Bambara groundnut has the ability to drought tolerance and has high nutritional value and is one than Legume crops untapped, which need attention. Therefore in this research, it will look at the relationship between osmotic stress caused by a concentration of PEG and drought tolerance to get some genotypes has ability drought tolerance.Methods: The experiment was conducted in the Tissue culture Laboratory, Department of Agronomy, Faculty of Agriculture, the University of Brawijaya, Malang, Indonesia in January-March 2019. The objective of the experiment was an evaluation of some morphological criteria to drought tolerance on the seedling for thirty genotypes of Bambara groundnut using polyethylene glycol (PEG) 6000 by three concentrations (0%, 5% and 10%). A complete randomized design was used for this experiment with three replicates.Result: The 10% PEG was the most suitable concentration to select Bambara groundnut lines for drought tolerance. Genotypes give different responses to concentrations of PEG. In susceptible lines, there are germination constraints, such as Prevent and germination delayed, the formation of hypocotyl length, root length, fresh weight and dry matter, while drought-tolerant lines can germinate normally. Obtained six lines that were tolerant to drought, five local, namely BBL 1.1, PWBG 5.2.1, PWBG 6, SS 2.4.2, SS 3.4.2 and one from Thailand which is Tvsu 86.
