Jack Algiere, farm manager at the Stone Barns Center for Food and Agriculture, inspects a young crop of sungold cherry tomatoes in one of his green houses on June 11. Stone Barns is a sustainable farming and learning facility for children and tour groups featuring Blue Hill, a top quality restaurant located on the property in Pocantico Hills, Hudson Valley, N.Y.

Never, if you ask heirloom tomato lover Carolyn Male. Male, author of 100 Heirloom Tomatoes for the American Garden (Workman Publishing), has grown more than 2,500 varieties of heirlooms, several of which she believes only she and one other person in this tomato-loving world are growing. "Why did I become this passionate about heirlooms?" the biologist asks. Her answer: "The biological diversity translates into tremendous varieties of colors, shapes, tastes and even foliage." She says she has introduced several hundred varieties of heirlooms to the USA. Male was raised on a farm in Loudonville, N.Y., where her parents grew "round, red tomatoes." "I find them boring," she says. She would be interested in hybrids, however, if it were possible to introduce certain disease tolerances into heirlooms from hybrids, she says. But even so, her favorites, and she's back growing tomatoes in Salem, N.Y., remain heirlooms. "Everytime I get a new (seed)," she says, "I can't wait to see what will grow." Longing for a perfect tomato? If so, whether you grow your own or plan to buy them at the farmers market, you're one of the millions counting down the days to the first taste of this summer's vine-ripened fruits. And if you're seriously tomato-obsessed, you're in good company there, too. "You take a bite and it's rapturous," says Laurel Garza, owner of Heirloom Tomato Plants, a nursery in Southern California. "People's eyes roll back in their heads." But wait. Is Garza talking about heirlooms or hybrids? The tomato-obsessed have firm, sometimes fanatical, opinions as to which is superior, with heirlooms getting most of the snooty vote. But Garza is talking about both. She and a growing number of tomato aficionados are challenging tomato lovers to sample certain hybrids that burst with flavor and thumb their noses at diseases. "There are a few carefully selected hybrids that are just as good as heirlooms," she says. "I taste everything I sell. Tomato love is something we do not take lightly." The tomato is by far America's most popular home garden crop. The obsessed will tell you that the quality of fruit picked in the garden when fully ripe far surpasses anything available on the market, even in season. SUBMIT PHOTOS: What does your garden grow? VEGGIES: Parents can help kids grow to love 'em REALLY A FAN? Visit Heirloom Tomato Festival in Napa Valley Heirloom die-hards may disagree, but Garza argues that some hybrids have earned the right to share the tomato tiara with heirlooms. These are not your daddy's hybrids. They're a big improvement over those produced in the early 1900s, designed to give tomatoes a longer shelf life, better disease resistance and productivity. To produce hybrids, scientists cross-breed several plants, giving the hybrid offspring the best qualities of both parents. Heirlooms, on the other hand, have been passed down from generation to generation. They are prized for their diversity of color, but they can be hard hit by diseases and have smaller and later yields. Which hybrids are getting good reviews? In a taste test reported in the March issue of Martha Stewart Living, the little hybrid Sapho is savored among several dozen others. George Ball, chairman of W. Atlee Burpee & Co., says his Brandy Boy won a blindfold taste test over Brandywine, considered a champion heirloom. Park Seed sold out its Glory seeds this season. One of Garza's favorites, Sun Gold, is also a staff favorite at White Flower Farm in Connecticut and Stone Barns Center for Food and Agriculture in New York's Hudson River Valley. Jack Algiere, the manager at Stone Barns, grows heirlooms and hybrids. Last summer, when late blight hit, he had to tear out many plants, but not Sun Gold or Mountain Magic, the only tomato known to be resistant to late blight. The disease hit a wide geographic area last summer from South Carolina to Maine and west to Ohio. Tomato growers were as distraught as the Whos in Whoville after the Grinch struck. What's the difference? But Mountain Magic was steadfast. Chef Dan Barber says the hybrid "tastes every bit as good" as an heirloom. His Blue Hill restaurants at Stone Barns and in Manhattan serve organic produce from Algiere's fields. The chef used Mountain Magic as one of his premiere tomatoes. "In August, we use tomatoes in every course," he says. "It's the time of year when tomatoes are the most important part of the menu." Mountain Magic is the magic of plant breeder Randy Gardner, who developed it when he worked at North Carolina State University. He is retired from the university but still works with several other plant breeders, including Martha Mutschler at Cornell. That's how Mountain Magic came to Algiere and Barber — Mutschler does tomato testing at Stone Barns. "I think they taste just as good or better than heirlooms," Mutschler says. Gardner acknowledges that "some of the people who grow heirlooms won't admit the hybrids are good." And so the arguments will continue between the heirloom lovers and the hybrid fans. The line is drawn in the garden dirt. Gardner calls for a truce. "There doesn't need to be a war," he says. Tomato varieties number in the thousands, have many wonderful and different flavors, and more are on the way. There are so many subtle differences it's as much fun as wine and olive oil tasting, Garza says. So what's to fight about? "People need to give hybrids a chance," she says, laughing. "If they don't, it's because they're snobs and don't know any better." Guidelines: You share in the USA TODAY community, so please keep your comments smart and civil.
