Screening of germplasm for tolerrance against major stem pests of soybean

Abstract

Field experiments were conducted during Kharif 2010-2011 and 2011-12, at the field of College of Agriculture, Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra). Twenty two germplasm were screened for tolerance against major insect pests of soybean. During 2010 Genotypes DSb 16 (2199.1kg/ha) with the highest yield under unprotected conditions was considered as tolerant check. Among the entries tested, two entries viz., SL-799, DSb-16 and three checks JS 93-05, JS-335 and MAUS-158 were categorized as high yielding entries. During 2011, the per cent yield loss in different genotypes ranged from 14.35 (PS 1466) to 61.56 (JS 97-52). Under protected and unprotected conditions yield obtained from JS 93-05 (1621.31 kg/ha) to DS 12-13 (2526.61 kg/ha) and from PS 1466 (1089.65 kg/ha) to DSb 16 (2199.06 kg/ha). Among the entries PS-1466 categorized as resistant high yielding entry. How to view point the article : Motaphale, A.A., Bhosle, B.B. and Khan, F.S. (2016). Screening of germplasm for tolerrance against major stem pests of soybean.

Resistance Level of Soybean Genotypes against Pod Sucking Bug (Riptortus linearis F. Hemiptera: Alydidae)

“…Damage by pod borer is resulted from the larvae boring into mature pods and seeds (Rahman et al, 2017). Pod sucking bug causes soybean seed become defleted, wrinkled and cannot be consumed resulted in yield loss more than 75% (Sari and Suharsono, 2011;Motaphale et al, 2016;Adie et al, 2022). The suitability of using resistant genotypes with other control components in pest management is a long-term problem solving due to its economically sound and easy to use (Soundararajan et al, 2013).…”

Correlation of Pests Resistance Levels and Seed Chemical Concentrations of Soybean Genotypes

“…While the major soybean disease is leaf rust (Phakopsora pachyrizi). Pod borer, pod sucker and armyworm caused seed yield losses ranges 79%-100% (Baliadi et al, 2008;Sari and Suharsono, 2011;Motaphale et al, 2016;Marwoto et al, 2017). In mungbean, the 36-75% yield loss was due to pod borer (Umbarkar et al, 2011;Indiati et al, 2021).…”
