CONFIRMATION OF DIGENIC INHERITANCE OF COTYLEDON COLOUR IN LENTIL (LENS CULINARIS)

Abstract

The F3 seeds harvested from F2 populations of five crosses between parents with orange and light green cotyledons were analysed. The F3 segregation confirmed the earlier reported digenic control of cotyledon colour in lentil. Further, four new crosses were made between F2 plants of different crosses which were raised from seeds with yellow and brown cotyledons. All Fl seeds had orangecotyledons. The F2 seeds harvested from Fl plants raised in phytotron were analysed immediately for cotyledon colour. The F2 seeds segregated in the ratio of 9 orange: 3 yellow: 3 brown: 1 green. The results from the new crosses also confirm digenic control of cotyledon colour in lentil.
