NC 3GEM is a large-fruited, fresh market tomato breeding line featuring deep oblate shaped fruits. Fruit is firm and crack resistant, flavor and texture have been rated as good. The plant Immature fruit of ‘NC 3GEM’ are uniform green (u gene) while mature fruit are bright red (ogc gene).
NC 3GEM has genetic resistance to late blight (Ph-2 and Ph-3 genes), verticillium wilt (Ve gene) and some races of fusarium wilt (I and I-2 genes), and the crimson (ogc) gene for increased lycopene content and improved red interior color of the fruit. In addition, ‘NC 3GEM’ is useful as a parent in crosses with other parent lines with the crimson gene in developing multiple disease resistant hybrids for vine-ripe, fresh-market production of large, high quality fruit.
Dr. Randy Gardner is a Professor Emeritus of horticultural science at NC State. He initiated the fresh-market tomato breeding program at NCSU in 1976 and ran it until his retirement in 2008. He developed the widely grown “mountain” series of tomato hybrids and released numerous other named hybrids and breeding lines that have been used in improvement of fruit quality and disease resistances worldwide. He has been widely recognized for his contributions to tomato breeding. Since his retirement in 2008, Dr. Gardner has concentrated on developing specialty type tomatoes of various sizes, colors, and shapes with improved fruit quality, marketable yield, and multiple disease resistances.
