“…This explanation was true for all other non-significant associations, with correlation coefficients closer to zero. Furthermore, these results suggested that resistance in soybean did not really depend on the nutritional factors nor space but presence of anti-nutritional factors which may not depend on the seed size or seed density (Sharma and Thakur, 2014c). The weak correlation between 100 seed weight with eggs and adults suggested that oviposition and adult emergence did not depend on 100 seed weight which was similar to what Dent (2000) reported that seed weight was a very complex variable in legumes and as such it does not have linear relationships with other variables (Acquaah, 2007).…”

“…The percent seed weight loss observed in this study was higher than the reported loss by Sharma and Thakur (2014a), which was 4.93%. Reports on losses due to bruchid damage vary from crop to crop (Sharma and Thakur, 2014b;Ebinu et al, 2016) and genotype to genotype (Sharma and Thakur, 2014c;Gevina et al, 2016). For example, common beans in Malawi have been reported to incur losses of up to 38%, Uganda reported up to 8%; while Kenya and Tanzania reported as high as 78% within six months of storage (Kananji, 2007).…”

“…The results on insect growth index (Table 4) which is an indicator of genotype suitability to Callosobruchus chinensis development, showed that the insect had the capacity to infest and develop on all soybean genotypes tested but with significant differences. Larval development within the seed depends on chemical composition of the grain (Sharma and Thakur, 2014c). The inability of C. chinensis to develop at the same rate in the genotypes would be an indication that genotypes had varying contents of saponin (Swella and Mushobozy, 2009), fat content (Tripathi et al, 2013) and proteincarbohydrates ratio (Srinivasan and Durairaj, 2007).…”

Soybean (Glycine max (L.) Merrill) is among the major food and industrial crops grown globally for its high protein and oil content. Lately, in Uganda, soybean reportedly faces challenges with a storage pest, Callosobruchus chinensis. This study was carried out to quantify the damage caused by the pest and identify the sources of resistance in the germplasm in Uganda. The study was conducted at Makerere University Agricultural Research Institute, Kabanyolo (MUARIK) in Uganda, during 2015 and 2016. Callosobruchus chinensis was used to challenge 498 soybean lines under no choice condition, in the laboratory. Results showed no significant differences in eggs laid amongst the different genotypes; however the genotypes performed significantly different (P< 0.05) for adult insect emergence, median development period (MDP), Dobie susceptibility index (DSI), growth index (GI), insect percent emergence (% IE) and seed weight loss (%WL). Genotype AVRDC G8527 had the lowest % IE (6.31), DSI (0.7), % WL (0.02) and GI (0.07), suggesting high resistance. Weight loss of up to 27% was recorded in genotype USA 7. There was a strong positive correlation between number of adults that emerged with DSI (r=0.87), eggs (r=0.88), % weight loss (r=0.73), and growth index (r=0.996). Cluster analysis revealed that AVRDC G8527, a resistant genotype was closely related to S-line 13.2A, a moderate resistant genotype. Regression analysis, revealed that adult bruchid emergence explain seed weight loss with 62% coefficient of determination; while seed colour could be used to determine genotype DSI with up to 74% coefficient of determination. Genotypes AVRDC G8527 and G89 were identified as the most resistant genotypes based on levels of DSI.

“…Higher percentage seed weight loss with higher susceptibility index found in susceptible mungbean genotypes rather than resistant genotypes. The seed weight loss due to bruchid attack varies from variety to variety (Gevina et al, 2016;Sharma and Thakur, 2014a) and crop to crop (Ebinu et al, 2016;Sharma and Thakur, 2014b). Higher percentage of seed weight loss (78%) has been recorded in common bean during six months of storage condition (Kananji, 2007).…”

Background: Mungbean is an important pulse crop due to its high protein content. Bruchid is a major storage pest which causes deterioration of seed quality as well as quantity. The grain losses directly affect the agricultural economy and also the human health. Therefore, this issue has to be addressed with high priority. Methods: To address this issue, we have initiated a study to screen the fifty-two mungbean genotypes against the bruchid attack. The initial phase of the experiment was carried out from 2015 to 2017 in the department of Genetics and Plant Breeding, University of Calcutta to the laboratory condition through the no choice test. Result: Using the parameter bruchid susceptibility index according to Dobie, four resistant, ten susceptible, seventeen moderately resistant and twenty-one moderately susceptible mungbean genotypes were identified. The host resistance genotype HUM-8, PM-11-51, APDM-84, VC-639 are identified as the most promising resistant genotype.

“…C. maculatus are sexually dimorphic in nature and males are easily distinguished from the females as females are larger in size than the males. Pesticides and fumigants are used to control storage pests in legumes but their application at higher doses leads to the accumulation of toxic residues in the treated products may mixed up in the daily diets too (Shaheen and Khaliq, 2005;Sharma and Thakur, 2014). However, identification of resistant genotypes by means of genetic improvement is an environment friendly approach to prevent bruchine infestation (Uddin and Adesiyun, 2012).…”

Background: Blackgram [Vigna mungo (L.) Hepper] is a rich source of protein. It is one of the major crops essentially involved in daily human diets. However, storage pest bruchine [Callosobruchus maculatus (F.)] is a major production constraint for legumes. A research was formulated to assess the bruchine resistance in 20 blackgram genotypes along with the biochemical analysis to find out the active biochemical components responsible for the resistance activity.Methods: The experiment was carried out during August- October, 2019 at Entomology Laboratory, National Pulses Research Center, Vamban, India. The experimental material comprised of 20 blackgram genotypes which were screened for bruchine resistance. Further, confirmatory trial was conducted with selected resistant entries and highly susceptible entries during October- December, 2019. Both experiments were carried out in completely randomized design and replicated three times. GC-MS analysis on the resistant and susceptible entries were performed to ascertain the active biochemical components conferring resistance.Result: Among the genotypes, TU 68 had comparatively late developmental time (days), less number of adult emergence, higher mean developmental period (days), less susceptibility index, less seed damage (%) and less seed weight loss (%). Genotype TU 68 was found to be resistant in the confirmatory trial also. Less number of adult emergence and higher mean developmental period indicated the delayed developmental period which is a mechanism of bruchine resistance. GC-MS analysis on resistant (TU 68) and susceptible (MDU 1) genotypes indicated the presence of active biochemical compounds with insectifuge activity in TU 68. Hence, TU 68 could be utilized in the hybridization programmeas donor for bruchine resistance.
