F2 Data from Hybrid 09H16


segregating F2 line

Hybrid 09H16 was an intentional cross between two large tomatoes with good flavor and some potential disease resistance to a unique line with a "Ailsa Craig' background that contained the apricot gene, high pigment (increased caroteniod levels) and green stripes (LA3399 from The Charles M. Rick Tomato Genetics Resource Center). The combination was made to obtain a range of novel types and to get the apricot gene expressed in a larger and better tasting line than currently found with the few available true apricot lines in gene banks. Any disease resistance from the 'Big Beef' parent, such as verticillium wilt, fusarium wilt race 1 and race 2, alternaria stern canker, stemphylium (gray leaf spot), nematodes (root knot) or tobacco mosaic virus, will be serendipitous.

     

The Apricot Gene "at"


typical apricot fruit with blush in center

The apricot gene is a unique flesh gene that was originally discovered at a market in Mexico on a collection trip. The fruit stood out from the other types around it. Its origin or line it was derived from was not known. Other than mapping and a few tester lines I do not believe this gene was ever used to develop a line that has been released.

Apricot is very similar in carotenoid composition to yellow fleshed fruit but segregates independently of that gene. Fruit color varies from yellow to orange but most fruits are a yellowish-orange color and usually have a blush of pink in the center. Prescense of the apricot gene can been differentiated from other yellow or orangish tomatoes that have a blush in the center (from the bicolor or ry gene) usually by its unique lighter colored flower petals.
