Interspecific triploid hybrid was developed between tetraploid cultivated species Gossypium hirsutum cv. MCU 5 and CO 14 and diploid wild species Gossypium anomalum. The F1 hybridity was confirmed by morphological and cytologicalstud. The ploidy level of interspecific F1 hybrid was triploid and male sterile. Maternal parents MCU 5 and CO 14 had erect growth habit, green stem, palmate leaves, thick and prominent leaf veins, cream petals and embedded stigma. MCU5 was with dense yellow anthers while CO 14 dense creamy anthers, whereas male parent Gossypium anomalum has spreading growth habit, dull violet petals, pale brownish green stem, creamy white, thin leaf veins, embedded stigma and strongly hairyness plant body. |
