“…The present findings are in agreement with Singh et al (2013) and Saroj et al (2021) who studied genetic diversity in Indian mustard including indigenous and exotic line and reported no relationship between place of origin and clustering of genotypes. Similarly other workers in different crops have reported similar inferences (Sharma et al, 2016;Choudhary et al, 2017). However, these results indicate that diverse origin is not sufficient as an index of genetic diversity and this kind of genetic diversity might be due to differential selection pressure, adaptation and acclimatization and environmental settings (Das and Gupta, 1984;Sharma et al, 2013).…”

Aim: The present investigation was designed to evaluate 150 diverse germplasm of Indian mustard along with five checks for seed yield and attributing traits. Methodology: A total of 150 genotypes of Indian mustard were evaluated in Augmented Block Design along with five check cultivars (Kranti, Maya, Pusa Bold, NPJ-112, RGN 73) in five blocks. Data were collected for 16 different quantitative traits on each genotype. Results: ANOVA revealed significant differences between genotypes for all traits studied. Seed yield plant-1 had significant and positive correlation with most of the yield contributing traits. For seed yield/plant, 15 accessions (DRMR-1722, BDJ-I-538, DRMR-4, JMG-113, DRMR-681, DRMR-1849, DRMR-1697, DRMR-1610, DRMR-1996, DRMR-107, DRMR-1588, DRMR-1379, DRMR-1995, IB-26, DRMR-2116) were significantly superior over best check. Interpretation: The present study was found useful for identification of diverse genotypes of Indian mustard for different yield attributing traits. The promising lines will be utilized in Indian mustard breeding for improving seed yield and oil content.

“…More similar genotypes are those that are dispersed closer to the origin and closer to one other, whereas genotypes that are scattered further apart are more divergent. (Sharma et al, 2016). Genotypes AVCP-1, PGCP-1, PGCP-13, CGD-1406, and CGD-1439 were scattered across apart in all four quadrates of the biplot indicating high genetic divergence across the genotypes.…”

Cowpea improvement is possible if the information on genetic diversity among existing genotypes is available. Principal Component Analysis and Mahalanobis D 2 analysis were used to analyse 30 cowpea genotypes based on eleven quantifiable traits. The whole variance was divided into eleven major principal components using PCA, with the top three PCs with eigenvalues >1 accounting for 69.47 per cent of the total variation. From the analysis of the first two PCs and Mahalanobis D 2 analysis, it was confirmed that genotypes viz., AVCP-1, PGCP-1, PGCP-13, CGD-1406, and CGD-1439 were scattered apart in all four quadrates of the bi-plot and fall in clusters with high inter-cluster distance representing maximum genetic variation. As a result, 30 cowpea genotypes had genetic and phenotypic differences that could be used to improve the cowpea by simple selection and crossing potential parents.

“…Diversity analysis based on agromorphological traits and microsatellitebased markers were also used in global germplasm collections of roselle (Hibiscus sabdariffa L.). It turns out that employed agromorphological traits and molecular markers have complemented each other and imparted greater resolution to understand the genetic diversity of roselle plant genetic resources (Sharma et al, 2016). In Passiflora, cytogenetic, molecular, and morphological analyses were compared with those of Passiflora capsularis L. and Passiflora rubra L., and it showed that molecular and morphological analysis were powerful tools for the categorization of the species (Amorim et al, 2014).…”

Narcissus pseudonarcissus, also known as daffodil, is a world-famous ornamental flower. In this study, for the first time, cross-pollinations between two widely cultivated N. pseudonarcissus varieties ‘Slim Whitman’ and ‘Pinza’ were performed. After eight consecutive years of cultivation, 27 reciprocal hybrids with different genotypes survived; 15 hybrids in ‘Slim Whitman’ × ‘Pinza’ and 12 in ‘Pinza’ × ‘Slim Whitman’. Twenty ornamental and agronomic characters were observed to evaluate the pattern and extent of genetic variability of the hybrids and relatedness with their parents. The hybrids showed great variation in most morphological characters compared with the parents, especially in leaf and flower characters. Hybrids SP03, SP04, SP05, SP12, SP13, PS04, PS06, PS07, PS08, and PS11 had evident growth advantage in some aspects compared with both parents. Of these hybrids, SP04 got novel flowers with white petals and an yellow-orange corona, and had the potential to become a new popular N. pseudonarcissus cultivar. Hybrids SP01, SP03, SP05, PS04, PS06, and PS07 also possessed a great ornamental value. Using cluster analysis based on morphological traits and random amplified polymorphic DNA (RAPD) molecular markers, genetic relationships among the reciprocal cross hybrids and their parents were further analyzed. The 27 reciprocal hybrids and their parents grouped into divergent clusters, showing that there was rich genetic variation among the hybrids tested. This study will pave the way for hybridization breeding programs of N. pseudonarcissus.
