Over active nature of human being is affecting the environment of earth in adverse manner. This is leading a threat to global sustainable agriculture development and ultimately food security. The Food and Agriculture Organization of the United Nations (FAO) defines "food security" as a state of affairs where all people at all times have access to safe and nutritious food to maintain a healthy and active life. This means that in order to enjoy food security, there must be on the one hand a provision of safe, nutritious, and quantitatively and qualitatively adequate food and, on the other, rich and poor, male and female, old and young must have access to it. "Green Revolution "has been one of the greatest achievements since the Second World War. The phenomenal increase of research based agricultural productivity has fed millions and served as the basis of economic transformation in many poor countries, especially on the Indian subcontinent. This "Green Revolution" has avoided dire predictions of death and famine in world particularly in Asia. But in present scenario agriculture land is decreasing continually, due to vast industrialization, there is continuous degradation of soil health by improper agriculture practices, and simultaneously there is drastic shift in population from rural area to urban area. All this is creating problems of hunger and malnutrition in developing countries. As Biotechnology science has given us a new tool to maintain food security. Conventional breeding, widely used during the Green Revolution era, no longer provides needed breakthroughs in yield potentials, nor the solution to the complex problems of pests, diseases, and drought stress. On other hand various components of Biotechnology i.e. Plant Tissue Culture, Marker Assisted Breeding, Genetic Engineering, has enormous potential to achieve the goal of to minimize Hunger and malnutrition as well as make the complex agricultural systems of world more productive and sustainable.

“…We observed that out of nine varieties expressing mismatches in two grouping methods, eight had an admixture ranging between 30-50% from other subpopulation, which may be one of the reasons of such mismatches. In an earlier investigation, 31 Indian mustard varieties had been grouped into five different clusters on the basis of multivariate analysis following Euclidean distance and UPGMA method [7]. In a similar study, population structure analysis had been carried out to determine the extent of genetic variation among 58 leafy mustard (B. juncea var.…”

“…In India, no comprehensive effort has been attempted so far to evaluate genetic diversity inherent in Indian mustard varieties except for few scattered reports [5][6][7][8]. As International Union for Protection of New Varieties of Plants (UPOV) has made it mandatory to have DNA fingerprinting profile for legal protection of a plant variety [9], there is an imminent need to establish a unique system for identification of promising cultivars of Indian mustard for their protection under the current IPR regime.…”

“…As International Union for Protection of New Varieties of Plants (UPOV) has made it mandatory to have DNA fingerprinting profile for legal protection of a plant variety [9], there is an imminent need to establish a unique system for identification of promising cultivars of Indian mustard for their protection under the current IPR regime. Further, many cultivars exhibit almost similar phenotypes/overlapping traits, so it becomes a herculean task to identify them on the basis of morphological characteristics [7], which entails the need of developing unique DNA fingerprints for their accurate identification.…”

In this study, we evaluated genetic diversity in a panel of 87 Indian mustard varieties using 200 genomic-SSR markers. A total of 189 SSRs resulted into positive amplification with 174 (92.06%) SSRs generating polymorphic products and 15 (7.94%) SSRs producing monomorphic amplicons. A total of 552 alleles were obtained and allele number varied from 2–6 with an average number of 3.17 alleles per SSR marker. The major allele frequency ranged from 0.29 (ENA23) to 0.92 (BrgMS841) with an average value of 0.58 per SSR locus. The polymorphic information content (PIC) value ranged from 0.10 (BrgMS841) to 0.68 (BrgMS519) with 0.39 as mean PIC value. The gene diversity per locus ranged from 0.13 (BrgMS841) to 0.72 (ENA23 & BrgMS519) with a mean value of 0.48 per SSR primer pair. Both Unweighted Neighbor Joining-based dendrogram and population structure analysis divided all the 87 varieties into two major groups/subpopulations. Analysis of molecular variance (AMOVA) inferred the presence of more genetic variation (98%) among individuals than among groups (2%). A total of 31 SSRs produced 36 unique alleles for 27 varieties which will serve as unique DNA-fingerprints for the identification and legal protection of these varieties. Further, the results obtained provided a deeper insight into the genetic structure of Indian mustard varieties in India and will assist in formulating future breeding strategies aimed at Indian mustard genetic improvement.

“…Genetic diversity among the population can be resolved utilising morphological, https://doi.org/10.17221/75/2022-CJGPB biochemical and molecular approaches (Mohammadi & Prasanna 2003). Evaluation of the genetic diversity in B. juncea using phenotypic characteristics has been carried out by many researchers (Singh et al 2010(Singh et al , 2018Sharma et al 2022). Heterosis breeding can play an important role in bringing self-reliance in the edible oil sector of India through increasing the productivity of mustard plants.…”

The present study was conducted to explore the variability generated through recombination breeding for nine economically important traits in Indian mustard (Brassica juncea L. Czern & Coss.). Delineation of the inbred lines to different gene pools, based on genetic diversity, enables their utilisation in hybrid breeding. The unweighted pair group method with arithmetic mean (UPGMA) and a Euclidean distance matrix was used to delineate the inbred lines to clusters. The variability was studied using the range and coefficients of variation of the traits. Significant variability was observed for all studied traits except for oil content and days to maturity. 128 Indian mustard genotypes were grouped into four distinct gene pools based on genetic diversity. A set of 20 most diverse genotype combinations was produced. Promising inbred lines were identified and recommended as donors for the respective trait. The pedigree analysis of the inbred line groups revealed, that recombination breeding caused a large diversity as confirmed by the assignment of inbred lines with the same parentage to specific clusters.
