“…The diverse responses of different genotypes to pathogens, varying in susceptibility, may stem from the complex interplay of resistance gene expression and the genetic background affecting genotype-pathogen interactions, as emphasized by Singh et al [13]. The dynamics of how hosts and pathogens interact are significantly shaped by both macro and micro environmental factors, ultimately influencing the disease's severity, as discussed by Tamang et al [14].…”

The increasing prominence of rapeseed-mustard on the global stage as vital oilseed crop is attributed to its high yield, low moisture requirements, cost effective production, and adoptability to diverse farming condition indicating the potential for a forthcoming yellow revolution role in India's oilseed production, facing challenges from various factors affecting yield and seed quality. Notably, white rust stands out as a significant biotic stressor, causing substantial losses in both yield and seedily, 17–34% yield particularly in oil content. To address this, utilizing resistant varieties is the most cost-effective and environmentally friendly approach for disease management. However, the available resistant sources are limited. In a recent study during the Rabi seasons of 2021-22 and 2022-23, thirty rapeseed mustard genotypes were assessed under white rust prevalent conditions. Out of 30 genotypes tested, none were found to be free of white rust disease infection and none were classified as resistant. However,11genotypes were registered as as moderately resistance, while, 19 genotypes fell under the were in the susceptible category. Promisingly, some genotypes exhibited resistance to white rust, offering potential for developing superior cultivars to effectively manage the disease in regions where mustard cultivation is prevalent. Aims: The study aimed to evaluate 30 rapeseed-mustard genotypes during the Rabi sessions of 2021-22 and 2022-23, focusing on their resistance to white rust. The primary objective was to identified genotypes with potential resistant traits, contributing to the development of superior cultivars for effective white rust management in regions where rapeseed-mustard cultivation is prominent. Study Design: Randomized Block Design. Place and Duration of Study: Experimental field of the Department of Plant Pathology, College of Agriculture, BUAT, Banda session 2021-22 and 2022-23. Results and Conclusion: None of the tested genotypes were found to be entirely free from white rust infection, and none of these achieved under resistance. However, the study identified 11 genotypes as moderately resistance and 19 genotypes fell into the susceptible category. Despite the challenges posed by white rust, sum genotypes demonstrated resistance, offering promising potential for the development of advanced cultivars. This finding holds significant for regions where rapeseed-mustard cultivation faces the threat of white rust, providing the basis for future efforts enhancing crop resilience and productivity.

“…According to Lin and Binns (1988), among the influencing parameters, soil element is generally persistent and may be regarded as fixed whereas weather parameters are unpredictable and contributed by year‐to‐year variation. GE interaction imposes a great challenge to plant breeders, as it can make genotypic selection erronious by diminishing the correlation between phenotypic and genotypic values, lowering the genetic gain under selection (Comstock & Moll, 1963; Tamang et al, 2021). It was observed that the magnitude of GE interaction was more in grain Fe content than grain Zn content which was consonant with the previous findings (Phuke et al, 2017; Prasanna et al, 2011).…”

Micronutrient malnutrition is a great burden towards attaining nutritional security for the vulnerable section of society, especially pregnant and lactating women, as well as preschool children in developing countries. Biofortification of lentil with iron (Fe) and zinc (Zn) may have a great impact on health and nutritional security as this food legume is the chief source of dietary energy and easily digestible protein for the vegetarian population. Assessment of genetic variability followed by ciphering genotype Â environment (GE) interaction are the vital endeavour towards the recommendation of Fe-and Zn-rich cultivars. Therefore, the present study was contemplated to appraise the genetic variability for Fe and Zn content among lentil genotypes followed by unravelling the effect of GE interaction for delineation of stable micronutrient-rich genotypes using HA-GGE biplot and REML/BLUP method.Preliminary studies with 125 lentil genotypes revealed the presence of adequate genetic variability concerning grain Fe (44.46 to 121.89 mg kg À1 ) and Zn (17.45 to 77.25 mg kg À1 ) content and other agronomic traits. Further, a multilocation evaluation trial with 30 promising genotypes at four diverse locations for consecutive 2 years detected a significant influence of environment and GE interaction on grain Fe and Zn content. Integration of HA-GGE biplot along with REML/BLUP analysis pertinently detected BCL-10212 and IPL-220 as 'ideal' for Fe content whereas IC-346092 and IC-521442 for Zn content. Moreover, IC-521442 was detected as most 'ideal' having richness in both Fe and Zn along with high stability over the locations.These genotypes offer a great opportunity to the lentil breeders for their utilization in a subsequent breeding programme towards developing Fe-and Zn-rich lentils. Present findings would be useful for the generation of recombinant lines for mapping and tagging of the genes/QTL controlling Fe and Zn content and developing the biofortified lentil cultivars.

“…Observed values for PC1 (Grain Fe/Zn) presented 88.17% and 72.15% of the total variation for Fe and Zn, respectively whereas PC2 (stability of the genotype) portrayed 5.54% and 22.71% of the total variation observed for Fe and Zn content, respectively. Earlier literature recommended that, the cumulative contribution of PC1 and PC2 should be more than 80% for judging the fitness of the methodology (Tamang et al, 2022).…”

Background: Micronutrient malnutrition is a severe peril for wellbeing of humankind, which can be holistically addressed through genetic biofortification. Lentil, proclaim as poor man’s meat can hold a great promise in global biofortification programme. The present study was designed to appraise genetic variability for Fe and Zn content and elucidate the role of Genotype × Environment interaction for delimitation of micronutrient enriched stable lentil genotypes integrating HA-GGE biplot with REML/BLUP. Methods: Grain Fe and Zn content of 44 lentil genotypes grown at three different locations of West Bengal during two consecutive years were estimated for deciphering the G × E interaction combining HA-GGE and REML/BLUP. Result: Results revealed substantial genetic variability for Fe (48.07 to 107.45 mg kg-1) and Zn (38.72 to 60.07 mg kg-1) in 44 lentil genotypes with significant influence of environment and GE interaction. The present study precisely detected ILL-10123 and VL-156 as the ‘ideal’ genotypes for Fe and Zn content, respectively in addition to non-redundant testing location. Identified genotypes and testing location aid in global biofortification programme for upscaling micronutrient concentration in lentil.
