Effects of the Nicotiana megalosiphon source of cytoplasmic male-sterility in Maryland tobacco cultivars and hybrids

, : Effects of the Nicotiana megalosiphon source of cytoplasmic male-sterility in Maryland tobacco cultivars and hybrids. Tobacco International 179(3): 56-58

In trials in 1974 in Upper Marlboro, Maryland, 6 male-sterile tobacco cultivars and 15 male-sterile hybrids containing N. megalosiphon cytoplasm were evaluated with their fertile counterparts. Average hybrid leaf yield (2.13 t/ha) was not significantly more than average cultivar yield (2.07 t/ha), but hybrids were earlier flowering and lower in plant total-N content than cultivars.
