Development and evaluation of India's first intraspecific cotton recombinant inbred mapping population for extra-long staple fibre traits.

Fibre quality improvement in is one of the long thought objectives for sustainability of cotton improvement. The efforts to transfer alleles in to for enhanced fibre quality is still under process across the world. To meet the future fibre quality demand in India, here we report development of recombinant inbred mapping population that has huge potential for precise mapping of extra-long staple traits.

Biochemical and molecular dissection of thermo-sensitive genetic male sterility in diploid cotton (Gossypium arboreum L).

Diploid cotton, due to its inherent problem of stamen brittleness, its found unsuitable for traditional method of hybrid seed production which involves hand emasculation followed by pollination. Due to shortfall in other methods viz., Genetic Male Sterility (GMS), as well as, Cytoplasmic Genetic Male Sterility (CGMS), hybrid seed production in diploid cotton becomes costly and thereby, covers less area among the total cotton grown area.
