...imation of heterosis and inbreeding depression are prerequisites to start hybrid development program. In this context, we explored heterosis and inbreeding depression in indigenous maize germplasm comprising inbred lines NCMLQ1, NCMLQ2, NCMLD1, NCMLD2, NCMLD3, and NCMLD4. ese genotypes were crossed to get ten F1 hybrid combinations, which were used...

The effective allele number and allele density are other criteria to show the spatial heterogeneity in a population. The average effective allele number (ne) per loci for TGC samples from the smallholders in the villages, TGC ex-situ conservation herd and the total population sample were calcul...

We assessed the level of genetic diversity and genetic isolation of different langur populations using Randomly Amplified Polymorphic DNA (RAPD) genetic markers. We collected 86 different samples (feces 64, hair 13, blood 5, tissues 4) from 5 geographic langur populations of Pakistan and Azad Jammu and Kashmir (AJK) and succeeded in extraction of DNA from 23 samples, which were used for further genetic analysis. RAPD makers...

Highly significant inbreeding depression was recorded for all traits indicating a dominant type of gene action. Heterosis was high for both crosses along with high inbreeding depression. All these results exhibit that the hybrid breeding is the best option for inbreds to exploi...

In this study, four wild specimens groups (ZSW, WZW, NNW, and FZW) and four cultured specimens groups (ZSC, WZC, NDC, and FZC) of M. unguiculatus were used to analyze their genetic diversity, population structure and understand the relationship between the wild and cultured specimens groups. The results showed that haplotype diversity (h) of the cultured specimens groups (from 0...

Meanwhile, the value of the genetic differentiation index (Fst) in all populations is zero (0), indicating that there is no differentiation between breeds at the observed loci.

Thus, we recommend the hybrid strategy of S. superciliaris ♀ × S. reevesae ♂ as the potential germplasm resources for further artificial reproduction. Population structure analysis and UPGMA tree indicated S. superciliaris and S. superciliaris ♀ × S. reevesae ♂ were clustered together that comprised of clade I, and S. reevesae and S. superciliaris ♂ × S. reevesae ♀...
