Pea In pea, a gamma ray inducedmutant cultivar ‘Wasata’ with tendrils instead of leaves (afila) was released in Poland in 1979. This cultivar was further used for breeding to produce the cultivar ‘Sum’ with short height. An afila type cultivar ‘Piast’ was released from the cross Sum × Metzer in Poland in 1995 (R. Madajewski, pers. commun.). The cultivar ‘Piast’ is a yellow seeded dry pea that combines high yield with good standing power and has been released in Great Britain in 1998 as ‘Ramrod’ (United Oilseeds, 1997). In the afila type cultivars, the leaflets are converted into tendrils but stipule leaves are still present. The plant habit leads to plant architecturethat allows good aeration, better light penetration and improvedcolour. The upright crop canopy gives high standing power that allows harvesting without choking the combines. It should be mentioned here that several semi-leafless pea cultivars that have derived from spontaneousafila mutants are also grown widely in Canada and other countries.
