Authors: K.S.C. Galv�£o, H.C.C. Ramos, P.H.A.D. Santos, G.C. Entringer, J.C.F. Vettorazzi and M.G. Pereira
This study aimed to improve grain yield in the full-sib reciprocal recurrent selection program of maize from the North Fluminense State University. In the current phase of the program, the goal is to maintain, or even increase, the genetic variability within and among populations, in order to increase heterosis of the 13th cycle of reciprocal recurrent se..

Genetic diversity in intraspecific hybrid populations of Eucommia ulmoides Oliver evaluated from ISSR and SRAP molecular marker analysis
Authors: J. Yu, Y. Wang, M. Ru, L. Peng and Z.S. Liang
Eucommia ulmoides Oliver, the only extant species of Eucommiaceae, is a second-category state-protected endangered plant in China. Evaluation of genetic diversity among some intraspecific hybrid populations of E. ulmoides Oliver is vital for breeding programs and further conservation of this rare species. We studied the genetic diversity of 130 accessions.. Read More»

Genetic diversity analysis of tree peony germplasm using iPBS markers
Authors: Y.B. Duan, D.L. Guo, L.L. Guo, D.F. Wei and X.G. Hou
We examined the genetic diversity of 10 wild species (populations) and 55 varieties of tree peony using inter-primer binding site (iPBS) markers. From a total of 36 iPBS primers, 16 were selected based on polymorphic amplification. The number of bands amplified by each primer ranged from 9 to 19, with an average of 12.88 bands per primer. The length of ba.. Read More»

Population genetic structure of the tropical tree species Aegiphila sellowiana (Lamiaceae)
Authors: C. Medri, E.A. Ruas, C.F. Ruas, P.S. Medri, M.E. Medri and P.M. Ruas
The Tibagi River, located in southern Brazil, is associated with a significant degree of environmental heterogeneity, along its 550 km extension. There is concern about the integrity of this river’s ecosystem, as human interference has been increasing. Aegiphila sellowiana (Lamiaceae) is an important pioneer tree species.. Read More»

Genetic diversity of Qatari date palm using SSR markers
Authors: K. Elmeer and I. Mattat
The genetic diversity in the date palm germplasm of 59 female accessions representing 12 cultivars from different locations in Qatar was investigated using 14 loci of simple-sequence repeat (SSR) primers. A total of 94 alleles, with a mean of 6.7 alleles per locus, were scored. The number of alleles per locus varied from 3 (primer mPdCIR090) to 11.. Read More»

Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines
Authors: K.J. Sa, J.Y. Park, S.H. Choi, B.W. Kim, K.J. Park and J.K. Lee
Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (S..

A novel random amplified polymorphic DNA-based strategy for genetic diversity analysis and identification of tomatoes
Authors: X. Cao, Z. Wu, R. Zhou, F.L. Jiang and Z.E. Yang
Cultivar identification diagrams (CIDs) provide a rapid and efficient approach for identifying cultivars based on random amplified polymorphic DNA (RAPD) markers. In this paper, 64 tomato cultivars were identified using a CID. Using RAPD profiles, clustering analysis was performed to analyze genetic diversity. The results showed that 8 RAPD primers could ..

Genetic diversity of wild soybean populations in Dongying, China, by simple sequence repeat analysis
Authors: Y.H. Wang, X.J. Zhang and S.J. Fan
Annual wild soybean (Glycine soja Sieb. et Zucc.), the ancestor of cultivated soybean (G. max), is believed to be a potential gene source for further improvement of soybean to cope with environmental stress. In this study, 10 simple sequence repeat (SSR) markers were used to evaluate the genetic diversity and population genetic structure in five wild soyb.. Read More»
