Redroot pigweed is one of the injurious agricultural weeds on a worldwide basis. Understanding of its interference impact in crop field will provide useful information for weed control programs. The effects of redroot pigweed on cotton at densities of 0, 0.125, 0.25, 0.5, 1, 2, 4, and 8 plants m(-1) of row were evaluated in field experiments conducted in 2013 and 2014 at Institute of Cotton Res...

In the present study, genetic linkage analysis was carried out to map the fiber color loci Lc 1 and Lc 2 on two brown cotton cultivars with SSR and EST-SSR markers in the reference map by F2 segregation populations. The Lc 1 locus carried by Xincaimian6 (Gossypium hirsutum L.) was flanked by the marker NAU2862 and NAU1043 on the long arm of Chromosome 07, with genetic distance 7.8 cM and 3.8 cM...
