Abstract
The genus Petunia is a compound of the diploid species, 5 with 14 chromosomes [P. axillaris (Lam) B.S.P., P. violacea Lindl., P. inflata R. Fries, P. parodii W.C.S., and P.hybrida] and one with 18 chromosomes (P.parviflora). Several authors have studied P. axillaris and P. violacea under the respective names of P. nyctaginiflora and P. integrifolia but more details concerning these species are given in Chap. 2. All species with 14 chromosomes were crossed and gave progenies except when P. inflata was pollinated by P. parodii. P. parviflora does not cross with species having 14 chromosomes. Recently however, somatic hybrids were obtained by Cocking (1980); see also Chaps. 10 and 11.
