DIGENIC CONTROL OF COTYLEDON COLOUR IN LENTIL (LENS CULINARIS)

Published on

In spite of reports suggesting digenic nature of inheritance of cotyledon colour in lentil,
the precise nature of gene interactions is unknown. A technique has been developed which
allows, with some experience, near-perfect identification of cotyledon colour in intact
seeds without removing testa. Such screening led to classification of the conventionally
known "yellow" cotyledons into two easily distinguished categories: yellow and brown
(dirty yellow). These two cotyledon colours are caused by dominant state of two unlinked
genes, designated as Y(for yellow) and B (for brownish or dirty yellow). Double dominant
condition YB gives orange (or red) cotyledons, while double recessive state yy bb produces
light green cotyledons.
