A. tuberculatus と A. esculentus (オクラ)との相反交雑の後代に育成された新複二倍体作物 A. tubercular-esculentus KUWADA (アオイ科の種,属間雑種に関する研究XI報) The New Amphidiploid Plant Named "Abelmoschus tubercularesculentus" Obtained from the Progeny of the Reciprocal Crossing Between A. tuberculatus and A. esculentus : Studies on Interspecific and Intergeneric Hybridization in the Malvaceae. IX.
The reciprocal crosses between A. tuberculatus and A. esculentus were made, and in the progeny of their hybridization a new amphidiploid plant was obtained. The reciprocal crossing between them was possible, and their crossability was about 20 %; and the germination percentage of the F_1 seeds obtained was about 60-80 %. The size of the F_1 seeds obtained from the cross A. tuberculatus x A. esculentus was similar to that of A. tuberculatus ; and that obtained from the cross A. esculentus x A. tuberculatus were intermediate between their parents.
