W. R. Ko, Sa, K. J., Roy, N. S., Choi, H. - J., Lee, J. K., Ko, W. R., Sa, K. J., Roy, N. S., Choi, H. - J., Lee, J. K., Ko, W. R., Sa, K. J., Roy, N. S., Choi, H. - J., and Lee, J. K., Analysis of the genetic diversity of super sweet corn inbred lines using SSR and SSAP markers, vol. 15, p. -, 2016.

In this study, we compared the efficiency of simple sequence repeat (SSR) and sequence specific amplified polymorphism (SSAP) markers for analyzing genetic diversity, genetic relationships, and population structure of 87 super sweet corn inbred lines from different origins. SSR markers showed higher average gene diversity and Shannon’s information index than SSAP markers. To assess genetic relationships and characterize inbred lines using SSR and SSAP markers, genetic similarity (GS) matrices were constructed.

Haplo-block structure of Southern African village chicken populations inferred using genome-wide SNP data

K. S. Khanyile, Dzomba, E. F., and Muchadeyi, F. C., Haplo-block structure of Southern African village chicken populations inferred using genome-wide SNP data, vol. 14, pp. 12276-12287, 2015.

This study investigated the haplo-block structure, haplotype sharing, and diversity in extensively raised chicken populations of Southern Africa. Two hundred ninety village chickens from Malawi (N = 30), South Africa (N = 132), and Zimbabwe (N = 128) were included in the study, from which 649, 2104, and 2442 haplo-blocks were observed, respectively. The majority of haplo-blocks were smaller than 25 kb in size and only five blocks were more than 2000 kb in size.

Development of SNP markers and their application for genetic diversity analysis in the oil palm (Elaeis guineensis)

P. W. Ong, Maizura, I., Abdullah, N. A. P., Rafii, M. Y., Ooi, L. C. L., Low, E. T. L., and Singh, R., Development of SNP markers and their application for genetic diversity analysis in the oil palm (Elaeis guineensis), vol. 14, pp. 12205-12216, 2015.

The genetic evaluation of oil palm germplasm collections is required for insight into the variability among populations. The information obtained is also useful for incorporating new genetic materials into current breeding programs. Single nucleotide polymorphisms (SNPs) have been widely used in many plant genetic studies due to the availability of large numbers of genomic sequences and expressed sequence tags. The present study examined 219 oil palms collected from two natural Angolan populations, a few hundred kilometers apart.
