Tobacco (Nicotiana rustica L.) is also the importance cash crops of India. Tobacco is one of the important commercial crops in the world. The data on heterosis calculated over mid parental value, better parent and standard check revealed superiority of some cross combinations. For cured leaf yield, the cross GC 1 X SK 49 showed significant positive heterosis over standard check, the cross Motihari Hemti X Sel.15-16, Motihari Hemti X HDM 4 and GCT 4 X SK 49 exhibited significant positive relative heterosis and heterobeltosis. A perusal of per se performance and heterosis indicated that hybrids GC 1 X SK 49, GCT 4 X SK 49, Motihari Hemti X Sel. 15-16 and GC 1 X Sel.15-16 were found promising for further evaluation and to exploit transgressive segregants. Heterosis is important for decide the direction of future breeding programme and to identify the cross combinations which are best for in conventional breeding designing.
