Analysis of genetic diversity and trait correlations among Korean landrace rice (Oryza sativa L.)

F. P. Li, Lee, Y. S., Kwon, S. W., Li, G., and Park, Y. J., Analysis of genetic diversity and trait correlations among Korean landrace rice (Oryza sativa L.), vol. 13, pp. 6316-6331, 2014.

This study analyzed 394 Korean rice landrace accessions, including 93 waxy varieties, for polymorphisms using 29 simple sequence repeat (SSR) markers. In total, 381 alleles served as raw data for estimating the genetic diversity (GD) and population structure. The number of alleles per locus ranged from 3 to 44 (average = 13.14). The expected heterozygosity and polymorphism information content (PIC) ranged from 0.0341 to 0.9358 (mean = 0.5623) and from 0.0783 to 0.9367 (mean = 0.5839), respectively.

A new reduced height gene found in the tetraploid semi-dwarf wheat landrace Aiganfanmai

Z. S. Peng, Li, X., Yang, Z. J., and Liao, M. L., A new reduced height gene found in the tetraploid semi-dwarf wheat landrace Aiganfanmai, vol. 10, pp. 2349-2357, 2011.

Aiganfanmai is a dwarf tetraploid wheat landrace (Triticum turgidum var. turgidum) that stably produces the semi-dwarf trait. Plant height varies from 80-105 cm under cultivation. Compared with tall durum wheat (T. turgidum var. durum) variety Langdon, we found it to have short spikes and seeds, besides a semi-dwarf character. We crossed Aiganfanmai with Langdon to analyze the genetic basis of the semi-dwarf trait.
