This condition is called albinism and is very rare. It is considered to be due to a genetic mutation that allows the plant to start growing without any or partial production of chlorophyll in selective plant parts. In the pea cultivars ‘Meteor’ and ‘Arkel’, the frequency of this mutation was determined to be 1 in 300 and 1 in 10,000 plants, respectively. Plants with complete albinism usually live for 15 to 20 days producing two to three nodal leaves, but plants with partial albinism can grow to maturity and reproduce. Temperature has been shown in other plant species to impact the incidence of albinism but this has not been verified in pea.
