Note 72 — A DEFENCE OF MENDEL’S PRINCIPLES OF HEREDITY.
Reading edition
The varieties used were Express, Laxton’s Alpha, Fillbasket, McLean’s Blue Peter, Serpette nain blanc, British Queen, très nain de Bretagne, Sabre, mange-tout Debarbieux, and a large “grey” sugar-pea, pois sans parchemin géant à très large cosse. Not counting the last two, five are round and three are wrinkled. As to cotyledons, six have yellow and four have green. In about 80 crosses I saw no exception to dominance of yellow; but one apparently clear case of dominance of wrinkled and some doubtful ones.
