At harvest, the occurrence of poorly-filled, imperfect (I) and well-filled, perfect (P) persim- mon seeds, their frequency and size in cvs. Jiro and Maekawa-Jiro were compared with sever- al other cultivars.<BR>1. Poorly-filled seeds of 'Jiro' and 'Maekawa-Jiro' became evident early in the growth period of the fruit; they were thinner than the well-filled normal appearing ones and parts of them became discolored (blackened) in late July. In September, they were almost entirely black.<BR>2. Imperfect seeds were most numerous in 'Jiro' and 'Maekawa-Jiro', moderate in 'Hanagosho' and 'Zenjimaru'; and the fewest in 'Saijo', 'Matsumotowase-Fuyu', and 'Fuyu'. They occurred in fruits with or without perfect seeds.<BR>3. At harvest the width and length of imperfect seeds were smaller or of equal size com- pared with those of perfect seeds. The average seed size in 'Jiro' and 'Maekawa-Jiro' was larger than those of other cvs. The thickness and fresh weight of imperfect seeds were al- ways less than those of perfect ones.<BR>4. In 'Jiro' and 'Maekawa-Jiro', 3040% of the imperfect seeds was embryoless, whereas 15% of the perfect seeds, which appeared normal, lacked an embryo.
