Abstract
To make clear the species of Korean Asiatic cotton, 21 Asiatic cotton varieties collected from China, Manchuria, Japan and Korea and preserved at suwon Crop Experiment Station were crossed to the tester stocks and cytological studies were made for their pollen mother cells. The results were summarized as follows: 1. In the all hybrids between the 21 collections and G. herbaceum tester stocks always one ring-four association was observed. 2. In the hybrids between additional 5 collections and G. arboreum tester stock ring-four or chain-four was not observed. 3. In the hybrids between G. herbaceum tester stocks and between G. arboreum tester stocks no ring-four or chain-four was observed, while in the hybrids between G. herbaceum tester stock and G. arboreum tester stock always one ring-four was observed. In the hybrids between collections also no ring-four or chain-four was observed. 4. From above results and together with the results reported in previous paper the species of Asiatic collections was inferred to the D.U. Gerstel's G. arboreum and their race was inferred to the J. Hutcinson's G. arboreum L. race sinense.
