Karyomorphological studies in Asiatic cottons. I. Karyotypic analysis of species and races of asiatic cottons based on chromatin content.

Abstract

Karyotypic analysis of Gossypium herbaceum (races persicum and wightianum) and G. arboreum (race indicum and bengalense) with two races in each species has been made on the basis of smallest, largest and absolute chromosome length. It is concluded that at species level G. herbaceum is primitive to G. arobreum and at racial level parsicum is primitive to wightianum in G. herbaceum and indicum is primitive to bengalense in G. arboreum
