Abstract
ATTEMPTS to produce a merogonic fully developed animal organism have been unsuccessful; plants appear to be more convenient subjects for this purpose. We know two androgenic haploids at the present time and both belong to the genus Nicotiana. One was produced by pollinating a triploid Nicotiana Tabacum plant (2n = 72) with N. Langsdorffii (2n = 18). From such a cross a Nicotiana Langsdorffii androgenic haploid with 9 somatic chromosomes was produced1. The other androgenic haploid was produced by pollinating the amphidiploid N. glutinosa × N. Tabacum = N. digluta. with N. Tabacum (2n = 48). From such a cross an androgenic N. Tabacum with 24 somatic chromosomes has been produced2.
