Abstract
This species is added to the group of Daturas in which the chromosomes of testerraces which represent different species have been compared with those of the standard Line 1 of D. stramonium D. discolor, used as the c? parent, can be crossed to all members of the Stramonium section. Crosses were made to 7 prime types of D. stramonium and to D. ferox and D. quercifolia. Seven chromosomes of D. discolor are the same as 7 of Line 1 in D. stramonium. Five are modified, 2 having the same ends as 2 modified chromosomes of D. ferox and D. quercifolia. Because of difference in size, one of these probably was produced by different interchanges in the different species.This publication has 2 references indexed in Scilit:
