Abstract A laboratory experiment was taken to study the “physical and biochemical basis of resistance in groundnut against bruchid, Caryedon serratus (Olivier)” at department of entomology, college of agriculture, svpua&t, Meerut during August 2018 to February 2019. Varietal screening of groundnut pods against bruchid were carried out with ten varieties and the performance of the varieties was assessed based on the physical and biochemical parameters. These varieties showed significant differences in the physical parameters selected for study such as pod length × width, pod shell thickness, test weight and inter granular space. Shell thickness contributed to resistance, while other parameters, pods size, test weight and inter granular space to susceptibility. Chemical parameters of those varieties showed significant differences for pod sugars, pod proteins, pod phenols and pod tannins. Pod sugars and pod proteins content had a positive effect on the development of the bruchid. While, pod tannins and pod phenols exerted a negative effect. Thus, resistance to groundnut bruchid is a multifaceted mechanism governed by both physical and chemical characters of pods.

花生对 bruchid、Caryedon serratus (Olivier) 抗性的物理和生化基础

摘要 2018年8月至2019年2月，在密拉特农业学院昆虫学系开展了“花生对锯齿鹬（Olivier）的抗性理化基础”的室内试验研究。 花生品种筛选针对 bruchid 的豆荚对 10 个品种进行了测试，并根据物理和生化参数评估了品种的性能。这些品种在选择用于研究的物理参数方面表现出显着差异，例如豆荚长×宽、豆荚壳厚度、测试重量和粒间空间。外壳厚度有助于抵抗力，而其他参数、豆荚大小、测试重量和颗粒间空间对易感性有影响。这些品种的化学参数显示出豆荚糖的显着差异，豆荚蛋白、豆荚酚和豆荚单宁。豆荚糖和豆荚蛋白含量对 bruchid 的发育有积极影响。同时，豆荚单宁和豆荚酚产生负面影响。因此，对花生 bruchid 的抗性是一个多方面的机制，受豆荚物理和化学特性的控制。
