“…Among the 100 mutants, 22 mutants were identified as tolerant types, 42 mutants observed to be medium shattering, 29 mutants showed highly shattering and 7 mutants falls under very highly shattering categories. These findings are similar to genotypic studies in Soyabean given by Gadde (2006), Khan et al (2013 ing. Gadde (2006) also found similar kind of results in Soyabean.…”

“…Highest shattering percentage was recorded by the mutants M1 (300 Gy) of CO (Gg) 7 and M95 (20 mM) of NM 65. Similar findings were given by Mohammad (2010) and Khan et al (2013) in Soyabean. CO (Gg) 7 was under very highly shattering type (76.56 %) and NM 65 showed highly shattering percentage of 67 % in M 2 generation.…”

“…In the present study, hundred mutants were selected based on field observations to shattering. Similar method of screening was reported by Yamada, et al (2009) and Khan et al (2013) in Soyabean. Under laboratory condition, the lowest pod shattering percentage was recorded by the mutants, M77 (30 mM) of CO (Gg) 7 and M58 (400 Gy) of NM 65.…”

Mungbean, (Vigna radiata (L.) Wilczek) occupies a unique position in Indian agriculture and has been grown under various agro-ecological conditions. It is cultivated in 1.61mha with production of 3.38MT and productivity of 474kg/ha in India. Mungbean pods are thin and brittle when dry, so shattering is a major problem. The loss of seeds by pod dehiscence is one of the major reasons for low yield in mungbean; thus, reducing the frequency of pod dehiscence is an important objective in mungbean breeding. Induced mutations, have offered a single and short alternative to conventional breeding including isolation, screening, selection and testing generation after generation. In this study, variability was induced by gamma rays and Ethyl methane sulphonate (EMS) in two greengram genotypes viz., CO (Gg) 7 and NM 65. Screening for pod shattering was carried out in M 2 and M 3 populations of greengram. The scoring for shattering was recorded at physiological maturity of the pod. The shattering percentage ranged from 14.56 (400 Gy) to 93.45 per cent (20 mM). A total of 100 shattering tolerant mutants were selected from field based on visual observation. These mutants were again scored under laboratory condition as per IITA method. A total of 12 mutants of CO (Gg) 7 and 10 mutants of NM 65 which were tolerant to pod shattering were identified in M 2 generation and forwarded to M 3 generation. These mutants were scored for pod shattering under laboratory condition and nine mutants viz., M26, M44, M46, M58, M70, M71, M84, M92 and M98 were found to be tolerant in M 3 generation. This study on identification and screening of the mutants tolerant to pod shattering with high yielding potential will help to increase the production of the pods to a greater extent.

“…Two soybean germplasm lines, namely EC 241778 and EC 241780, were identified as promising sources of resistance to ASR after rigorous screening of 982 germplasm lines ( Patil et al, 2004 ). In another study conducted during the Kharif season of 2008 in Dharwad, India, 84 soybean genotypes were tested for ASR resistance in natural epiphytic environments, and these two germplasm lines (EC-241778 and EC-241780) were found as resistant genotypes ( Khan and Tyagi, 2013 ). However, the first rust-resistant cultivar developed in India is DSb 21 (JS 335 × EC 241778), which was developed by the University of Agricultural Sciences, Dharwad, and released in 2015 ( Immadi et al, 2022 ).…”

Soybean (Glycine max L.) is an important crop in Asia, accounting for 17% of global soybean cultivation. However, this crop faces formidable challenges from the devastating foliar disease, Asian Soybean Rust (ASR), caused by Phakopsora pachyrhizi, a biotrophic fungus with a broad host range, causing substantial yield losses (10–100%) in Asia. This comprehensive review consolidates knowledge on ASR, encompassing its impact, historical perspectives, genetic diversity, epidemic drivers, early detection, risk assessment, and sustainable management strategies of ASR in the region. ASR has expanded globally from Asia, reaching Africa and Americas, driven by wind-dispersed urediniospores. Genetic diversity studies reveal the complexity of P. pachyrhizi, with distinct populations exhibiting varying virulence patterns. Factors affecting ASR epidemics in Asia include host susceptibility, landscape connectivity, climate, and environmental conditions. Understanding the interplay of these factors is essential for early intervention and control of ASR in soybean fields. Effectively managing ASR can exploit the utilization of diverse intervention strategies, encompassing disease forecasting, automated early detection, disease resistance, fungicide application, and biological control. A pivotal aspect of successful, sustainable disease management lies in reducing the ASR pathogen virulence and preventing it from developing fungicide resistance, while the highpoint of effectiveness in disease control is attained through a synergistic approach, integrating various strategies. In summary, this comprehensive review provides insights into multifaceted approaches that contribute to the development of sustainable and economically impactful soybean production in the face of the persistent threat of ASR in Asia.
