An analysis was made of the relationship between yield and tenderometer readings of smooth- and wrinkled-seeded types of pea (Pisum sativum L.) cultivars. The analysis involved 13 smooth-seeded cultivars and 31 wrinkled-seeded cultivars in 16 cultivar trials that were carried out at two locations during five seasons with varying sowing periods. The results showed that for the two types of cultivars a distinction could be made in the relationship between yield and tenderometer readings in the relevant range for processing (90¿150). At tenderometer readings lower than 120 the relative yield of wrinkled-seeded cultivars is higher than that of the smooth-seeded types, while at tenderometer readings above 120, the relative yield is lower. Consequences for a sliding price scale are indicated.
