Crossability relationship between wild cotton Gossypium armourianum and Gossypium gossypoides with American cotton
DOI: 10.37992/2023.1401.016
Abstract
The goal of the current study was to assess the possibility of interspecific hybridization for transfer of jassid-resistant genes from the two wild cotton species Gossypium armourianum (Kearney (2n=2x=26) D2A) and Gossypium gossypoides (Standley (2n=2x= 26) D6) into the genotypes of cultivated Gossypium hirsutum. The study demonstrated that seeds were successfully produced from crosses between G. hirsutum and G. armourianum using the cultivated tetraploid as a female parent. The reciprocal cross did not produce any seed. None of the crosses were successful in combination with G. gossypoides. Most of the boll shedding in reciprocal cross was between 2-6 days after pollination. MCU5 x G. armourianum had the highest germination percentage whereas; CO17x G. armourianum had highest survival percentage of the seedlings. With further backcrosses or chromosome doubling, the segregants can be further utilized for the introgression of different relevant traits like sucking pest resistance against leafhopper and whitefly along with resistance to other insect pests.
