“…Clustering of genotypes was irrespective of their geographical origin and no definite correlation was observed between genetic and geographical diversity. The present findings are in agreement with Saroj et al (2021), Sharma et al (2021), Devi et al (2017), Gupta et al (2015), Pandey et al (2013), Singh et al (2013), Dar et al (2010) and Doddabhimappa et al (2010). Further diverse origin may not always be used as an index for genetic diversity because divergence may also be due to genetic drift and selection pressure as concluded by Kole and Chakraborty (2012) and Murty and Arunachalam (1966).…”

In the present study, a set of 36 Indian mustard genotypes were evaluated in three replications for twelve agromorphological traits. D 2 analysis was done to study the diversity pattern which enabled the grouping of genotypes into 11 clusters. Cluster I was the largest (D 2 =7.53) comprising of 20 genotypes followed by cluster II (D 2 =7.20) of 7 genotypes, while other 9 clusters contained one genotype each. Estimates of average inter cluster distance revealed that clusters IX and XI were most divergent (D 2 =118.49) followed by clusters V and XI (D 2 =88.48). Hence, crossing between genotypes Pusa Agrani × Rohini (cluster IX × cluster XI); PM-28 × Rohini (cluster V × cluster XI) may yields a considerable amount of heterosis in F 1 generation. Days to maturity (31.9 %) had the highest contribution, followed by seed yield per plant (25.4 %), days to 50% flowering (13.33 %), beak length (7.30 %) and 1000 seed weight (6.67 %) towards the observed genetic diversity. Selection for divergent parents based on concerned traits could enhance the development of transgressive segregants with increased vigor in Indian mustard.

Globally, the gap between the production of nutritious quality crops and their consumption is widening, resulting in high rates of malnutrition and micronutrient deficiencies. Our goal is to examine the rich tapestry of studies on underutilized crops (UUCs) and consider their potential role in alleviating food and nutritional insecurity. Published research articles on UUC were retrieved from databases, such as Web of Science, Google Scholar, and Scopus. The key terms used were “UUC,” “neglected crops,” and lists of UUC, which were frequently cited in literature. A bibliometric innovative approach, such as reference co‐citation, co‐citation, and co‐word analysis, was used. We observed an annual growth rate of 6.4% in UUC research outputs with the number of annual publications increasing from less than 700 article publications in 2000–3000 article publications in 2021. It is also developing into a noticeably interdisciplinary research field with more collaborations and institutional affiliations. The most relevant affiliated countries in UUC‐related studies are developed and transition countries, such as the United States of America, China, India, the United Kingdom, South Africa, Australia, and Germany. The pressing and emerging research studies in UUC‐related studies are genetic diversity and identification, agronomic knowledge, seed improvement, and environmental stresses. There is a shift in the focus of UUC studies, which provides a deeper understanding of the global trends and directions that have evolved in UUC studies over the past two decades. This result provides researchers and policymakers in the field of UUC with a useful tool for decision‐making on UUC.

“…Therefore, parameters such as genotypic and phenotypic variance, heritability, and genetic advance are crucial for understanding the inheritance patterns of traits and determining their heritability. Understanding genetic correlations between traits aids breeders in optimizing selection efficiency by identifying favourable trait combinations and mitigating negative correlations (Sharma et al, 2021) [17] .…”

Mustard is a widely cultivated oilseed crop in India, known for its high yield potential and suitability for both sole cropping and intercropping. In the rabi season of 2015-16, a study was conducted involving 64 different genotypes and six check varieties using an Alpha lattice design with three replications to assess various yield attributing traits. The findings indicated substantial genotypic and phenotypic coefficient of variation, particularly for traits such as the number of siliqua per plant and grain yield per plant. Traits like siliqua per plant and plant height showed high heritability (>60%) and significant genetic advance as a percentage of the mean (>20%), suggesting the prevalence of additive gene action. Analysis of character association revealed a positive and significant correlation between grain yield and traits like days to maturity, plant height, primary branches per plant, siliqua length, siliqua per plant, and test weight, implying the potential for simultaneous improvement of these traits alongside grain yield. Path coefficient analysis highlighted siliqua per plant as having a high direct positive effect on grain yield, with its correlation coefficient with grain yield nearly equating its direct effect. This underscores the importance of siliqua per plant as a selection criterion for enhancing mustard seed yield, suggesting a focus on this trait for further improvement.
