Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines

K. J. Sa, Park, J. Y., Choi, S. H., Kim, B. W., Park, K. J., and Lee, J. K., Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines, vol. 14, pp. 7502-7518, 2015.

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 (SSR) markers. Based on a population structure analysis, the 80 maize inbred lines were divided into three groups: I, II, and admixed.

Evaluation of wheat landrace genotypes for salinity tolerance at vegetative stage by using morphological and molecular markers

A. Shahzad, Ahmad, M., Iqbal, M., Ahmed, I., and Ali, G. M., Evaluation of wheat landrace genotypes for salinity tolerance at vegetative stage by using morphological and molecular markers, vol. 11, pp. 679-692, 2012.

Identification of new sources of salt tolerance is particularly important to develop crop varieties suitable for saline soils. We evaluated 129 Pakistani and 58 exotic wheat landraces/cultivars grown in Hoagland’s hydroponic nutrient solution, under control (tap water equivalent to 10 mM salt) and salt stress (200 mM NaCl) conditions. Forty-four genotypes were also tested under 250 mM NaCl stress.
