<i>Gossypium hirsutum </i>plants with increased fiber strength comprising a fiber strength allele spanning the GLUC1.1A gene from <i>Gossypium barbadense</i>

摘要

This invention relates to the field of agriculture, more specifically to the use of molecular biology techniques to alter fiber-producing plants, particularly cotton plants, and/or accelerate breeding of such fiber-producing plants. Methods and means are provided to alter fiber qualities, such as increasing fiber strength. Methods are also provided to identify molecular markers associated with fiber strength in a population of cotton varieties and related progenitor plants.

主权项

1. A non-naturally occurring Gossypium plant, and parts and progeny thereof, comprising at least one fiber strength allele which is derived from Gossypium barbadense of a fiber strength locus on chromosome A05 wherein said plant is a Gossypium hirsutum plant and wherein the fiber strength allele which is derived from Gossypium barbadense is located on chromosome A05 of Gossypium barbadense: (a) between AFLP marker P5M50-M126.7 and SSR marker CIR280, (b) between AFLP marker P5M50-M126.7 and SSR marker BNL3992, (c) between AFLP marker P5M50-M126.7 and SSR marker CIR401c, or (d) between SSR marker NAU861 or the GLUC1.1 gene and SSR marker CIR401c, said Gossypium hirsutum plant comprising a Gossypium hirsutum allele of at least one marker locus on chromosome A05 selected from the group consisting of CIR139a, BNL3029.A and NAU1042.A.
