Summary
A study of the progeny of a periclinal chimera of the type L1 green: L2 green: L3 yellow, which could be recognised by the occurrence of yellow areas in the middle of the leaflets, showed a high rate of change to L1 green: L2 green: L3 green. This is explained as being caused by L3 cells at axillary meristems being replaced by the products of division of L2 cells due to occasional tangential divisions by the latter. The results add confirmation to the hypothesis that many bud-sports in potatoes which are now L1 normal: L2+L3 mutant, arose as L1 normal: L2 mutant: L3 normal.
