“…In the present study, the highest expected GAM was observed for the largest leaf area, smallest leaf area, fruit fresh mass, number of leaves, number of fruits per plant, leaf dry mass, number of primary branches, fruit yield, leaf chlorophyll content, days to 50% flowering and leaf fresh mass ( Table 4 ), respectively. The authors of [ 14 , 46 , 50 ] reported similar findings of high genetic advance over a mean number of leaves and other related traits. High GAM values indicate that these traits are simply inherited; the heritability is most likely due to additive gene effects and selection may be effective in early generations for these traits [ 30 , 31 , 32 ].…”

“…The heritability for the number of fruits, fruit fresh mass, stem yield, fruit yield and total biomass was low, despite high genetic advance ( Table 4 ). Such traits are more influenced by the environment, making selection ineffective for them as indicated by [ 45 , 46 ]. Furthermore, traits that exhibit high heritability with moderate or low genetic advance can be improved by inter-mating the superior accessions of the segregating population developed from multiple crosses and the desirable genes can be accumulated in the lines as stated by [ 46 , 47 ].…”

On the other hand, an association of high heritability with high genetic advance is an indication of additive gene effects and consequently, a high genetic gain from selection would be anticipated [ 14 , 48 ].…”

Nightshades are among many underutilized and neglected African indigenous leafy vegetable (AILVs) species, and if adequately exploited, they could improve food, nutrition and income among the rural population. Morphological characterization of available accessions is key for the breeder to identify and select superior accessions as parents for utilization in breeding programs. Fifteen accessions of nightshade were evaluated for morpho-agronomic variation in an open field trial implemented in a randomized complete block design with three replicates across the two growing seasons. The accessions exhibited significant (p < 0.0001) differences in all quantitative traits. The data analysis showed that Scabrum (805.30 g/plant) followed by Ncampus (718.60 g/plant) produced the highest fresh leaf yield; for fruit fresh yield, the accession NigSN18 (1782.00 g/plant) recorded the highest, followed by ManTown (1507.90 g/plant). The accession N5547 had the tallest plants (66.83 cm), followed by accession Timbali (62.31 cm). The first four principal components (PCs) accounted for 86.82% of the total variation, which had an eigenvalue greater than 1. The cluster analysis grouped the accessions into 14 clusters based on their genetic similarity. Results of genetic studies revealed that phenotypic coefficient variation was higher than genotypic coefficient of variation for all parameters evaluated, indicating the environmental influence on the expression of these traits. Both GCV and PCV were higher for the largest leaf area, moderate to high for the remaining characters and low for leaf fresh yield per plant. High heritability coupled with genetic advance as a mean percentage (H2-70.59%, GAM-142.4%), indicating the presence of additive gene effects. Hence, selection can be employed for the improvement of this trait in nightshades. The study revealed sufficient genetic variability in the nightshade accessions, which can be exploited for crop improvement.

“…ISSR markers are potential markers in identifying genetic diversity compared to other markers and allow the study of the diversity of specific regions of the genome at several locations simultaneously (Mengistu et al, 2004). ISSR markers has been used well for genetic diversity of cuscuta (Tajdoost et al, 2012), Persian violet (Asadi et al, 2016), narcissus (Jiménez et al, 2009), Solanum nigrum L. (Suganthi et al, 2018). Also, genetic diversity of different Turkish narcissus has been studied using SRAP markers (Zeybekoğlu et al, 2019).…”

To evaluate the genetic diversity of Iranian Narcissus genotypes (e.g., Shomal, Shastpar, Shahla, Yasuj, Shiraz-1, Shiraz-2, Kuchak-e-Atri, Dutch, Khosf-1, Khosf-2, Birjand, and Tabas), different RAPD and ISSR primers were examined at the Plant Breeding Laboratory of the Faculty of Agriculture, University of Birjand, Iran. In sum, RAPD and ISSR primers produced 189 and 80 high-resolution bands. The average values of PIC, Ht, Hs, Nm, DST, FDT, NA, Ne, H, and I indices were 0.287, 0.369, 0.089, 0.486, 0.279, 0.760, 1.952, 1.459, 0.282, 0.437 for RAPD markers and equal to 0.297, 0.380, 0.099, 0.524, 0.278, 0.732, 1.978, 1.495, 0.303, 0.467 for ISSR markers, respectively. The analysis of molecular variance based on the RAPD and ISSR markers showed 23 and 13 % variations for intra-populations and 77 % and 87 % changes for inter-population variabilities, respectively. Cluster analysis based on the RAPD and ISSR markers grouped genotypes into four clusters. Based on RAPD and ISSR markers, the PCoA analysis also showed that the first three components justified equal to 96.9 % and 97.9 % of the total variance, respectively, indicating the dispersion of the primers used. In general, it was concluded that the genetic diversity of narcissus species could be employed for breeding programs.
