Further evidence suggests that mutations are indeed present at detectable frequencies in the differentiated somatic tissues of both seed and vegetatively propagated plants.

Ideotype Research and Plant Breeding,nd it is encouraging that yield gains have been sizeable and sustained (Duvick, 1977; Austin et al., 1980; Riggs et al., 1981; Wych and Rasmusson, 1983; Wych and Stuthman, 1983). We should take satisfaction in and applaud conventional plant breeding.
