Abstract

Investigations were made with five oriental varieties of tobacco types Prilep (P 10-3/2, P 84, P 23 and P-7) and Yaka (YK-23) as mother parents, semi-oriental variety Forcheimer Ogrodowny (FO) as father parent and their five F1 hybrids, for the characters time of flowering and length of the growing period from transplanting to the end of harvest. The trial was set up in the field of Tobacco Institute-Prilep in randomized block system with four replications. The aim of the investigations was to use heterotic effect for growing of tobacco crop in various locations and, through determination of the mode of inheritance of investigated characters in F1 progeny, to show directions in breeding early- and late-maturing varieties. The period from transplanting in field to 50% of flowering ranged from 53 (P-23 x FO) to 63 days (P-84 x FO) and the period from transplanting to the end of harvest from 100 (YK-23 x FO) to 131 day (P-84 x FO). Inheritance of the two stages is different in all hybrids of F1 generation. In the period of 50% of flowering, the early-maturing parent is prevailing and the heterosis is negative (P-23 x FO, P-7 x FO and YK-23 x FO), while at the end of harvest the late-maturing parent is prevailing and the heterosis is positive ( P 10-3/2 x FO).The obtained hybrids make a good basis for further selection.
