Study the screen the green gram varieties against pulse beetle (Callosobruchus chinensis L.)

Abstract

The screening of green gram varieties against the pulse beetle viz. Virat, Shikha, Pusa Ratna, Pusa Vishal, Pusa 1431, TJM 3, PDM 139, IPM 99-125, IPM 2-14, IPM 2-3 and MH 421 were studied against the pulse beetle. The varieties, Pusa Vishal and TJM 3 was the most preferred host for egg-laying, while the least preferred variety was MH 421. The maximum mean adult emergence was in Pusa Vishal and the minimum in MH 421. The maximum seed damage up to (68.33%) was observed in Pusa Vishal, while minimum (33.33%) damage occurred in MH 421. The weight loss was highest in Pusa Vishal with 27.03 percent and was lowest in MH 421 and IPM 2-3 with 12.90 and 16.23 percent. Germination percent recorded in varieties MH 421 showed the average highest infected seed germination (17.77%), while variety Pusa Vishal showed the lowest infected seed germination (5.33%). And Germination percent was recorded in varieties Virat showed the average highest Healthy seed germination (93.33%), while variety IPM 2-3 showed the lowest Healthy seed germination (78.67%).
