1. The crosscompatibility in the reciprocal crosses between "Nori-Asa, an amphidiploid crop raised between Abelmoschus esculentus and A. Manihot, and its parents, and also the characters and meiotic division in the sesquidiploid hybrids obtained among them were studied . 2. The set % of pods was almost the same between "Non Asa" x esculentus and "Nori-Asa" x Manihot, and those in the reciprocal crosses between the two plants of these two combinations were lower. 3. The number of seeds per pod was larger in "Nori-Asa" x esculeletus than in "Nori Asa" x Manihot, and those in the above two crosses were smaller than in the respective reciprocal crosses. 4. The size of F1 seeds obtamed by Manthot x "Non Asa" was srmilar with that of the selfed mother, while those obtained by "Nori-Asa" x esculentus and "Nori-Asa" x Manihot were smaller than those of the selfed mother respectively. The F1 seeds obtained by esculentus x "Nori Asa" were larger, compared with those of the selfed mother.
