GAINESVILLE, Fla. — In their quest to develop higher quality mandarins, University of Florida Institute of Food and Agricultural Sciences researchers are zeroing in on the traits that will help them breed the best fruit.
Last year, they released the mandarin cultivar currently known as ‘7-6-27,’ which UF/IFAS researchers say is soaring with interest, and with more than 100,000 trees already ordered.
In a newly published study, Fred Gmitter, a UF/IFAS horticultural sciences professor, and his colleagues, including doctoral student Yuan Yu, found genetic markers for fruit quality traits that will be useful in future cultivar-breeding efforts.
Scientists wanted to know whether, for example, genetic markers – or “signposts,” as Gmitter calls them — for qualitative and quantitative traits in one group of mandarins lined up with these traits in other mandarins. Qualitative traits would be such things as peel or flesh color, while quantitative traits would include weight, size or shape.
