He grew up in the Northeast and did his undergraduate work at Rutgers University in the area of Plant Sciences. He worked summers with Dr. Frederick Hough and Dr. Catherine Bailey in the Tree Fruit (peach, apricot, apple, pear) Breeding Program and with Dr. Gojko Jelenkovic in the Blueberry and Strawberry Breeding Programs. While there he discovered that the chromosomes of the octoploid strawberry pair as if the plant was a diploid (Byrne and Jelenkovic, 1976. Can. J. Genet. Cytol. 18:653-659).
He did his graduate studies at Cornell University in Ithaca, New York in the field of Plant Breeding and Biometry with minors in Plant Pathology and Entomology. During this period he spent two years in Colombia, South America at CIAT (Centro Internacional de Agricultura Tropical, International Center of Tropical Agriculture) where he studied mite and thrips resistance in the tropical root crop, cassava (Manihot esculenta).
In 1980, his first job after graduating was in California at the International Plant Research Institute where he led their cassava production and breeding programs. Unfortunately, this young company had financial issues so in 1983 he moved to Texas A&M University to assume the duties of Stone Fruit Breeder in the Department of Horticultural Sciences.
Over the years he has taught classes in Plant Domestication, Fruit Production, and Tropical Horticulture in addition to leading trips with students to Costa Rica and Mexico to see tropical horticultural production and research.
He has run the Stone Fruit Breeding Program since 1983. The objectives of this program were initially to develop yellow-fleshed peaches adapted to the low and medium chill zones of the world. Early medium chill releases such as ‘Texstar’, ‘TexKing’, ‘TexPrince’, and ‘TexRoyal’ extended the harvest season by 3-4 weeks in this zone.
Low chill work in south Texas (Weslaco) and in collaboration with programs in Thailand (Royal Project) has resulted in six yellow-fleshed peach releases: ‘Tropicprince’, ‘TexFirst’ and the Thai Tiger series of 4 low chill peaches released for use in Thailand. These are also available in the USA as ‘Tropic Zest’.
In the early 1990s, the program shifted its emphasis to expand its work to include the development of new products for this zone. To accomplish this, the program incorporated traits such as white flesh, sub-acid flavor, non-melting flesh, nectarine, and flat shape into the breeding population. This involved collaborative work with Stone Fruit Breeding programs in Brazil, China, Japan, and Mexico. This work has resulted in over 20 releases including the following released in the USA:
Another 10 selections are currently being prepared for release.
In the early 1990s, working with Dr. Robert Basye a rose breeder and retired Professor of Mathematics, he began the Rose Breeding and Genetics Program which was enhanced by the donation of the breeding stock from the Father of the Miniature Rose, Ralph Moore. The focus of the program is to develop disease (black spot, Cercospora, Rose rosette) resistant and heat tolerant roses. The research emphasis is the development of genomics-based breeding tools to accelerate breeding progress.
He has led the national Specialty Crop Research Initiative programs entitled “Combating Rose Rosette Disease” and “Tools for Polyploids” Planning Grant as well as participated in the RosBREED II project which focused on discovering genetic tags useful for the breeding of roses and peaches. Ongoing projects involve the development and integration of breeding tools to utilize genomic information in polyploid crops and to rapidly phenotype plants for productivity and stress tolerance using remote sensing technology. The integration of these tools will lead to accelerated development of sustainable crop varieties.
He chairs the National Clean Plant Network for Roses that serves the rose industry and community by ensuring that there is a source of virus tested rose propagative material available to produce the best performing rose plants possible.
He is the Project Director for the Specialty Crop Research Initiative project entitled, “Tools for Genomics-Assisted Breeding in Polyploids: Development of a Community Resource”. This project brings together computational geneticists and polyploid crop breeders to develop and validate the computational tools needed to seamlessly incorporate the genomics-based data available into applied breeding programs to accelerate breeding progress.
