The genetic control of the photosynthetic capacity of a single leaf was studied in rice. The photosynthetic capaclty was estimated as the amount of oxygen evolved that was measured by oxygen polarography using a multi-channel apparatus. The amount of oxygen evolved by the F1 plants and the F2 populations of the two reciprocal crosses; Zaiyeqin 8 (high capacity) × Shinshukaneko (low capacity) and Jukkoku (high) × Naxi (low), were measured. The frequency distribution of the amount of oxygen evolved which was measured at a fixed period of measurement in the F2 populations showed a normal dlstribution.
