“…Additionally, difficulty in sporulation and conidia production under laboratory conditions, especially of S. botryosum, imposes a great affliction for intervening blight risk. Moreover, previous findings were limited to the screening of lentil genotypes against S. botryosum (Podder et al, 2013;Das et al, 2017;Razzak et al, 2018) and A. alternata (Roy et al, 2021). To the best of our knowledge, this is the first report of successful isolation of S. botryosum in India and further confirmation of the pathogen through sequencing by using ITS and Stemphylium-specific gpd1 and gpd2 primers.…”

Lentil is a food legume grown in the Indo-Gangetic plains including lower Gangetic Bengal (LGB). Lentil productivity in this zone is severely impeded because of the prevalence of several biotic cues. Plausible reports regarding the status of disease scenario and the associated risk factors are missing. Therefore, judicious crop management strategies are lacking. An intensive survey of 267 farmers’ fields was conducted over 3 years in major lentil-growing districts of LGB to evaluate the disease incidence and prevalence. Additional insights were generated, apprehending isolation and characterisation of associated pathogens through spore morphology and molecular markers as well as elucidating the role of biophysical factors in influencing disease development. Climate change has shifted the disease dimension of lentil and precipitated new disease complexes of great risk, which was reflected through geospatial mapping results in the present study. The prevalence of three major diseases, namely collar rot (Sclerotium rolfsii), lentil blight complex (LBC) incited by both Alternaria and Stemphylium, and lentil rust (Uromyces viciae-fabae), was ascertained through cultural and molecular studies and contextualised through pathogenicity appraisal. This study is the first to investigate the complex mixed infection of Alternaria alternata and Stemphylium botryosum, successfully isolating S. botyrosum in India, and confirming the pathogens through sequencing by using internal transcribed spacer (ITS) primers and Stemphylium-specific Glycerol-3-phosphate dehydrogenase 1 (gpd1) and gpd2 primers. Unlike late planting, early planting promoted collar rot infestation. LBC and rust incidence were magnified in late planting. Soil texture resulted in the spatial distribution of collar rot disease. The surveyed data also highlighted the potential role of resistant cultivars and cropping pattern intervention to ensure associational resistance towards addressing the disease bottleneck in lentil.

“…It is rising as a serious threat in West and South Asia, North America, and severely spread as a minor disease in Saskatchewan, Canada (Yadav et al, 2017). Previous works conducted in Bangladesh and India measured 62% of losses and sometimes complete crop failure was resulted due to extensive defoliation during the early stage of the pod setting (Razzak et al, 2018;Alam et al, 2017a). Since then, it has got prominence due to its increased occurrence and severity in many other countries like Hungary, Canada, Australia, Egypt, Syria, USA, Iran (Chen et al, 2009).…”

“…The prevalence of Stemphylium blight in most of the varieties was found maximum during the flowering stage followed by pod setting stage and maturity stage but it may differ with varieties. It results in huge economic loss due to the production of low quantity and quality of grain and seed (Razzak et al, 2018).…”

L entil (Lens culinaris Medik.), one of the classic founder crops is an annual, herbaceous selfpollinating grain legume grown in winter-season belonging to subfamily Papilionoideae of family Fabaceae/Leguminosae (Schaefer et al., 2012). Western Asia is the place where cultivated lentil (2n=14) is assumed to have been first originated and domesticated. Later, it spread quickly to Africa, southern and central Europe, the Mediterranean basin, and Indian subcontinents (Matny, 2015). Seven taxa systematized into four species were described in the most recent classification, namely L. culinaris ssp. culinaris, L. culinaris ssp. tomentosus, L. culinaris ssp. orientalis, L. culinaris ssp. odemensis, L. ervoides, L. lamottei, and L. nigricans (Wong et al., 2015). They are rich in proteins, minerals, prebiotics, carbohydrates, cholesterol lowering soluble fibers, and are naturally low in phytic acid so often stated as poor's man meat for the lower economic class. Aside from nutritional properties, lentil is important for the dryland cropping system in rotation to cereals because of their N-fixing capacity. Also, its crop residues can be used as feed for animals (Gupta et al., 2013;Subedi et al., 2014). The total cultivated area of lentil is estimated at around 6.10 million hectares with annual production and productivity of 6.33 million tons and 1.04 mt/ha, respectively in the world.

“…So to feed the huge population and for sustainable food security, identification of blight resistant genotypes is must. Previous studies identified various lentil lines as Resistant, Moderately Resistant, Moderately Susceptible and Susceptible at different growth stages (Razzak et al, 2018). The present research was carried out to compare yield and yield characters of 40 moderate resistant lines of lentil and screening best genotypes for future use.…”

Blight is an important disease that cause devastating yield loss now a days. That’s why, an investigation was carried out at the Regional Agricultural Research Station (RARS), Bangladesh Agriculture Research Institute (BARI), Barishal for screening of lentil germplasms against stemphylium blight in terms of yield and yield attributes. To find the best genotype, 40 moderately stemphylium resistant lentil lines/ genotypes were used and their different yield contributing characters were analysed. In this study, it has been observed that the long delay of 1st flowering was recorded in BD-5982 and BD-5996 while early flowering in BD-3927 and BARI masur-7. The highest 50% flowering days was recorded in BD-3983, BD-4024, BD-4053 etc. and lowest in BD-3922. Long maturation period of 111.5 days was recorded in BD-4024 and that of short maturity date was recorded in BD-3924 and BD-3927. The highest plant height was observed in BD-3974 and lowest was in BD-4127. The maximum number of branches per plant was observed in BD-3936 and BD-4024 and minimum was found in BD-4097. Maximum number of pods per plant was recorded in BD-3922 and minimum number of pods per plant was in BD-4053. The lowest number of seeds per pod was recorded in BD-4053. The highest 100 seed weight was recorded in BD-5986 and the lowest was observed in BD-4127. Maximum biological yield was recorded in BD-4053 and minimum was in BD-5989. The highest and lowest grain yield was recorded in BD-5983 and BD-4024, respectively. This finding will help researcher to develop new variety in near future. Asian J. Med. Biol. Res.
