Abstract

Low maize productivity on Madura Island is caused by low water availability. One of the strategies used to overcome the problem of low maize productivity in Madura is to assemble maize varieties resistant to drought stress. This study aims to determine the resistance of hybrid maize candidates in the germination phase using Polyethylene Glycol (PEG 6000). All genotypes were germinated using the paper roll test in plastic method, then moistened using a mixture of aqudesh with PEG 6000 according to the treatment. The data obtained was analyzed using the Analysis of Variance (ANOVA) at the 5% level, and if it shows a significant effect then the Duncan Multiple Range Test (DMRT) is carried out at the 5% level. The results showed that the corn genotype and PEG 6000 concentration affected all the parameters tested, so there were character differences between one genotype and the other. The genotypes resistant to drought stress in the germination phase using PEG 6000 were G1 and G5. The moderately tolerant genotypes were G3, G7, and G8, while the genotypes sensitive to drought stress were G2, G4, G6, G9, and G10.
使用聚酯胶粘剂(PEG 6000)对玉米混合玉米在发芽阶段的干旱根部进行评估
马杜拉岛的玉米产量低是由缺水造成的。在马杜拉,克服玉米产量低问题的策略之一是组合抗干旱胁迫的玉米品种。本研究旨在利用聚乙二醇(PEG 6000)测定候选杂交玉米萌发期的抗性。所有基因型均采用塑料法纸卷发芽试验,然后根据处理情况用混水与PEG 6000混合湿润。获得的数据在5%的水平上使用方差分析(ANOVA)进行分析,如果它显示出显著的影响,那么在5%的水平上进行邓肯多元范围检验(DMRT)。结果表明,玉米基因型和PEG 6000浓度对所有试验参数都有影响,因此玉米基因型与玉米基因型之间存在性状差异。peg6000在萌发期抗干旱胁迫的基因型为G1和G5。中度耐旱基因型为G3、G7和G8,干旱敏感基因型为G2、G4、G6、G9和G10。
