Abstract

Eleven chickpea varieties were screened for their biochemical resistance to the pulse beetle (Callosobruchus chinensis L.), a serious pest of the stored pulses. The varieties were found to arrest the growth and development of C. chinensis, at grub stages which were indicated by different parameters viz., oviposition, adult emergence, weight loss, developmental period and growth index. Among the various biochemical analyzed, high growth index was observed in the varieties PKG 2 (0.61), BG 1003 (0.62), BG 1053 (0.62) and PKG 1 (0.71). Low growth index recorded in PG 3 (0.52), BGM 547 and PG 186 (0.56) may be attributed to low phenol and tannin content. Similarly the varieties PKG 1, BG 1003 and BG 1053 with less phenol, flavonoids and tannin content recorded more growth index as compared to moderate resistance varieties PG 4, PBG 1 and PG 114 PBG 1, BGM 547 and PG 114 were found to be moderately resistant and PKG 1, PKG 2, BG 1053 and BG 1003 as highly susceptible, shows the major role of trypsin inhibitor in protein resistance to C. chinensis. The highest protease activity inhibition acts as antimetabolites to C. chinensis, inhibit to the feeding of grubs as result higher trypsin content varieties showed relative resistance. The correlation between different antinutritional factors and growth index of the grub also showed a negative relationship.

鹰嘴豆品种对中国斑蛾抗性的生化基础。(鞘翅目:豆象科)

对11个鹰嘴豆品种进行了对脉冲甲虫(Callosobruchus chinensis L.)生化抗性的筛选。结果表明，不同品种在蛴螬期(产卵期、成虫羽化期、体重减轻期、发育期和生长指数)均能抑制蠋蝽的生长发育。在生化分析品种中，PKG 2(0.61)、bg1003(0.62)、bg1053(0.62)和PKG 1(0.71)的生长指数较高。PG 3(0.52)、BGM 547和PG 186(0.56)的生长指数较低，可能是酚和单宁含量较低所致。同样，苯酚、黄酮类和单宁含量较低的品种PKG 1、BG 1003和BG 1053的生长指数高于中抗性品种PKG 4、pbg1和pg114，其中PKG 1、BGM 547和pg114为中抗性品种，PKG 1、PKG 2、BG 1053和BG 1003为高敏感性品种，说明胰蛋白酶抑制剂在对中国紫荆蛋白抗性中的主要作用。蛋白酶活性最高的品种作为抗代谢产物，抑制了蛴螬的摄食，因此胰蛋白酶含量较高的品种表现出相对抗性。不同抗营养因子与蛴螬生长指数呈负相关。
