(1) Studies on the resistances to Phytophthora Parasitica RElNKlNG and Sylepta derogata FABRI- clus of "Nori-Asa " (Abelmoschus glutino-textilis), an amphidiploid crop induced between Abel. esculeletus and Abel. Manihot, were made in comparison with those of its parents. ( 2 ) According to the field observation under natural infection and the inoculation experiment,the resistance to Phytophthora parasitica was quite low in Manihot and high in "Nori-Asa " as well as in esculeletus. ( 3 ) At the end of July, owing to the beginning of appearance of Sylepta derogata, esculentus sowed at the beginning of April and May was slightly damaged, while esculeletus sowed at the begljnning of June and July. Manihot and " Nori-Asa " sowed at different time between the beginning of April and July were not or little damaged. At the end of August, September and October, owing to the season of the greatest appearance of Sylepta derogata, all individuals of esculeletus and " Nori-Asa " sowed at different time between the beginning of April and July were damaged, but Maeeihot was only slightly damaged. (4) The resistance to Sylapta derogata was the highest in Malcihot, the lowest in esculentus, and " Nori-Asa " was the intermedium of the parents, though rather resembling the escule,etus.
