Screening of blackgram genotypes against spotted pod borer

Genotypic assessment of black gram (Vigna mungo L) combating against major insect pests

“…The data displayed in [12] who examined nine black gram entries against B. abaci in multiple-choice test and reported that two entries, KU-99-20 and NDU 5-7 are secondly resistant recording significantly lowest of whitefly population (egg, nymph and adult) as compared to the susceptible genotypes IPU 02-043, KU-7-602, KU-7-618 and Mash 1-1 and highly susceptible for the genotypes like KU-7-504 and KU-7-505. The present findings were also in agreement with the results of Kumar and Singh (2014) [5] who observed 25 blackgram genotypes for resistance to major insect pests, including whiteflies (Bemisia tabaci), found that VBG10-024 and KU-11-06 had the highest populations of white flies, while ACM05007 and TPU-4 had the lowest populations, followed by UH-08-05Similarly Bhople et al, (2017) [2] who evaluated the resistance of the mungbean genotypes to whiteflies. Ten genotypes in total were selected and an experiment using a random block design with three replications was carried out.…”

“…The rest of genotypes ATU-2204 (2.33/trifoliate leaves) followed by BDU 2021-2 (2.33/trifoliate leaves), Phule U1018-15 (2.33/trifoliate leaves), PU-62 (2.33/trifoliate leaves), ATU-2205 (2.67/trifoliate leaves) and BDU-2021-1 (2.67/trifoliate leaves), recorded the highest population of leaf hopper and highly affected entries as compare to earlier entries. Present findings are similar with work ofKumar and Singh (2014)…”

“…The observation based on yields obtained at the time of harvesting, highest yield even after the pest attack was recorded in AKM 4, followed by KM 2293, AKM 09-2, IPM 3066, and ML 1628 respectively. [5] who tested 25 blackgram varieties for resistance against leaf hopper. The results obtained was the minimum damaged s of leaf hopper was in TU-631, followed by ACM05-007 and TPU-4, while it was maximum in RUG-44.…”

Mining legume germplasm for genetic gains: An Indian perspective

“…Black gram is a grain legume of Indian origin, primarily cultivated in South Asian regions. Although black gram is an important legume, its productivity level is very poor compared to that of other legumes, which can mainly be attributed to a lack of good plant ideotypes and resistance sources for major diseases in its cultivated gene pool ( Kumar and Singh, 2014 ; Shanthi et al, 2019 ; Subramaniyan et al, 2022 ). Therefore, to identify donors for desired agro-morphological traits, 484 accessions have been characterized on qualitative and quantitative traits; a good deal of variation was observed in flowering and maturity period and in yield ( Ghafoor et al, 2001 ).…”
