Development of Superior Fibre Quality Upland Cotton Cultivar Series 'Ravnaq' Using Marker-Assisted Selection.

Marker-assisted selection (MAS) helps to shorten breeding time as well as reduce breeding resources and efforts. In our MAS program, we have targeted one of previously reported LD-blocks with its simple sequence repeat (SSR) marker(s), putatively associated with, at least, four different fibre quality QTLs such as fibre length, strength, micronaire and uniformity. In order to transfer targeted QTLs from a donor genotype to a cultivar of choice, we selected donor genotypes L-141 and LN-1, possessing a fibre quality trait-associated LD-block from the chromosome 7/16.

Features of Chromosome Introgression from L. into L. during the Development of Alien Substitution Lines.

The creation of L./ L. chromosome-substitution lines is an important method to transfer agronomically valuable traits from into .

Small RNA regulation of ovule development in the cotton plant, G. hirsutum L.

Background: The involvement of small RNAs in cotton fiber development is under explored. The objective of this work was to directly clone, annotate, and analyze small RNAs of developing ovules to reveal the candidate small interfering RNA/microRNAs involved in cotton ovule and fiber development.

Results: We cloned small RNA sequences from 0-10 days post anthesis (DPA) developing cotton ovules.
