摘 要：
In 1951, the author planted four varieties of cotton plants on the grounds of Fukien Agricultural College. Three of them, Delfos, Delta Pine, and Ring Improve were varieties of Gossypium hirsutum and fuzz-seeded. The fourth variety called Chang-Tze was o. Gossypium nanking and tuft-seeded. There were no other cotton plants growing on our grounds or nearby. In April of the same year four plants of G. hirsutum were inarched with G. nanking The results are summarized in the table Ⅰ. Besides the varietion of fuzz on the seed as indicated in the above table, changes of some other characters have also been noticed. The seeds of the hybrids are larger than those of their parents. The hybrid plants grown from the seeds produced from the branches of G. hirsutum are taller and ripen earlier than those of the preceding generation. The characters of the hybrid are closer to G. nanking than to G. hirsutum. This is probably due to the fact that G. nanking has been cultivated in China for a much longer period than G. hirsutum, and is therefore more apt to be better adapted to the local environment, and thus is able to exert more influence on the hybrid. This abservation of cotton plants in Fukien further confirms the findings of I. V. Michurin on the inheritance of acquired characters. Thus the difficulty to hybridize G. nanking and G. hirsutum is hereby overcomed.
