A G1 block at Clemson Simon Scott, Clemson University Phil Baugher has suggested that at G1 block would be of use to the nursery industry on the east coast. The block would be able to supply substantial amounts of budwood (>4 - 5,000 buds) of commercially significant material to nurseries for propagation. The trees maintained in the block would be tested on a regular basis for the presence of PNRSV, PDV, and PPV + ???
Simon Scott, Clemson University Phil has in the past purchased budwood from the Southeastern Budwood Program. 4,000 buds of Julyprince? Location of this block at Clemson meets the needs of the nursery industries in both Tennessee and the northeastern section of the country. Budwood matures sufficiently early to be available for June budding (June 1) and is available for budding in August.
Simon Scott, Clemson University Funding for the establishment of this block was provided in the 2010 FTNCPN proposal. The site (3.5 acres) has been identified, is being prepared (cultivation, soil testing and installation of the irrigation system are complete) Nematode analysis and soil fumigation will be completed in the next two months. The goal is for the block to be ready to accept trees by November/December 2011
Simon Scott, Clemson University The material in this block will be subject to the same testing as material in the blocks of the Southeastern Budwood Program (PNRSV, PDV, and PPV using ELISA). It will not be assessed for trueness-to-name. That will be the responsibility of the person submitting material for inclusion in the block.
Simon Scott, Clemson University Questions/discussion: What cultivars should be entered into the block? Commercially significant Past experience indicates that this block cannot act as a repository and survive. General categories, specific names?
Simon Scott, Clemson University How should the block be managed? Discussions with interested parties are needed in the following areas. Is entry into the block on a no charge basis? If so material is available (presumably) to all who request it. Should a charge for growing the material be levied? – The block has to be pruned, sprayed and fertilized and may last longer than funding for the FTNCPN.
Simon Scott, Clemson University If proprietary material is entered in to the block (coded labeling) and the submitter has sole access to that material, is a contract detailing the responsibilities of both parties (Clemson University/FTNCPN??) and the submitter needed. How long should material reside in the block? Trees will be approx 4 years-old before yielding large amounts of budwood.
Simon Scott, Clemson University What is the commercially significant life-span of most peach varieties? Julyprince and Scarletprince released by USDA in June 2004. Tested blocks were established by the Southeastern Budwood Program in 2008. Extensive plantings since. When will they be supplanted? 2022???
