Cotton is one of the most important natural fiber crops in the world. Its growth and yield is greatly limited by drought. A quantitative trait locus (QTL) analysis was therefore conducted to investigate the genetic basis of drought tolerance in cotton (Gossypium spp) using 188 F2:3 lines developed from an inter-specific cross between a wild cotton species, G. tomentosum, and an upland cotton, G. hirsutum (CRI-12).

Mapping quantitative trait loci for five forage quality traits in a sorghum-sudangrass hybrid

J. Q. Li, Wang, L. H., Zhan, Q. W., Liu, Y. L., Zhang, Q., Li, J. F., and Fan, F. F., Mapping quantitative trait loci for five forage quality traits in a sorghum-sudangrass hybrid, vol. 14, pp. 13266-13273, 2015.

The identification of quantitative trait loci (QTLs) affecting forage quality traits enables an understanding of the genetic mechanism of these loci. The aim of the present study was to detect QTLs for the whole-plant protein content (WP), whole-plant fat content (WF), neutral detergent fiber (NDF), acid detergent fiber (ADF), and whole-plant ash content (WA) using a population of 184 F2 individuals from a cross between sorghum Tx623A and sudangrass Sa. Correlation analysis was performed between the five forage quality traits.

Genetic analysis of grain shape and weight after cutting rice husk

J. R. Fu, Zhu, L. X., Sun, X. T., Zhou, D. H., Ouyang, L. J., Bian, J. M., He, H. H., and Xu, J., Genetic analysis of grain shape and weight after cutting rice husk, vol. 14, pp. 17739-17748, 2015.

Grain shape and weight are the most important components of rice yield and are controlled by quantitative trait loci (QTLs). In this study, a double-haploid population, derived from the cross of japonica CJ06 and indica TN1, was used to analyze QTLs for grain shape and weight under two conditions: normal growth with unbroken husk and removing partial husk after flowering. Correlation analysis revealed that these traits, except grain weight, had a connection between the two conditions.
