22-5 is a cross between PRL-Midichi and an advanced semi-leafless PRL breeding
line. Midichi is most widely used marrowfat pea variety in Japanese processing and is listed on the Japanese food safety programme and is the main variety used in New Zealand.
Midichi is a short, early flowering leafed variety with resistance to powdery mildew and good tolerance to grain colour bleaching. 22-5 was developed specifically to create a variety with the processing characteristics of Midichi, and higher yield in a semi-leafless background.
