Diallelic analysis to obtain cowpea (Vigna unguiculata L. Walp.) populations tolerant to water deficit

E. V. Rodrigues, Damasceno-Silva, K. J., Rocha, M. M., Bastos, E. A., Rodrigues, E. V., Damasceno-Silva, K. J., Rocha, M. M., and Bastos, E. A., Diallelic analysis to obtain cowpea (Vigna unguiculata L. Walp.) populations tolerant to water deficit, vol. 15, p. -, 2016.

The purpose of this study was to identify parents and obtain segregating populations of cowpea (Vigna unguiculata L. Walp.) with the potential for tolerance to water deficit. A full diallel was performed with six cowpea genotypes, and two experiments were conducted in Teresina, PI, Brazil in 2011 to evaluate 30 F2 populations and their parents, one under water deficit and the other under full irrigation. A triple-lattice experimental design was used, with six 2-m-long rows in each plot. Sixteen plants were sampled per plot.

Selection of an effective microsatellite marker system for genetic control and analysis of gerbil populations in China

X. Y. Du, Li, W., Sa, X. Y., Li, C. L., Lu, J., Wang, Y. Z., and Chen, Z. W., Selection of an effective microsatellite marker system for genetic control and analysis of gerbil populations in China, vol. 14, pp. 11030-11042, 2015.

Although gerbils have been widely used in many areas of biological research over many years, there is currently no effective genetic quality control system available. In the present study, we sought to establish a microsatellite marker system for quality control and con­ducted an optimized analysis of 137 microsatellite loci in two labora­tory gerbil populations and one wild population.

Potential of hypocotyl diameter in family selection aiming at plant architecture improvement of common bean

A. M. C. Oliveira, Batista, R. O., Carneiro, P. C. S., Carneiro, J. E. S., and Cruz, C. D., Potential of hypocotyl diameter in family selection aiming at plant architecture improvement of common bean, vol. 14, pp. 11515-11523, 2015.

Cultivars of common bean with more erect plant architecture and greater tolerance to degree of lodging are required by producers. Thus, to evaluate the potential of hypocotyl diameter (HD) in family selection for plant architecture improvement of common bean, the HDs of 32 F2 plants were measured in 3 distinct populations, and the characteristics related to plant architecture were analyzed in their progenies.
