Prescreening Slash Pine and Cronartium Pedigrees for Evaluation of Complementary Gene Action in Fusiform Rust Disease
Stelzer, H. E., Doudrick, R. L., Kubisiak, T. L., and Nelson, C. D. 1999. Prescreening slash pine and Cronartium pedigrees for evaluation of complementary gene action in fusiform rust disease. Plant Dis. 83:385-389. Single-urediniospore cultures of the fusiform rust fungus were used to inoculate seedlings from 10 full-sib families of a five-parent slash pine diallel at two different times in 19...
متن کاملDecline in Values of Slash Pine Stands Infected with Fusiform Rust
Losses in product values due tofusi form rust , caused by Cronart ium quercuum (Berk.) Miyabe ex Shiraifi sp. fusiforme, were estimatedfrom four, 2.5-yr-old slash pine, Pinus elliotii Engelm., plantations planted in southern Mississippi over a range of sites with different growth potential and expected rust infection levels. The percentage infected stems rangedfrom 2.5% to 62% at age 2.5. The c...

متن کاملGenetic Resistance to Fusiform Rust in Southern Pines and White Pine Blister Rust in White Pines—A Contrasting Tale of Two Rust Pathosystems—Current Status and Future Prospects
Damage or mortality from pathogens can reduce productivity of forest plantations, as well as significantly harm natural forest ecosystems. Genetic resistance within the host species is the first line of defense for tree species. Resistance breeding programs for the native fusiform rust and exotic (to North America) white pine blister rust diseases are two of the longest concerted efforts in for...
متن کاملEvaluation of Resistance to Fusiform Rust in Loblolly Pine from East Texas
A set of 21 loblolly pine families produced by crossing trees from east Texas were tested for resistance to fusiform rust disease. The parents of these families were surviving trees in stands that experienced extensive mortality in the 1960s due to southern pine beetle infestation. Seedlings were grown in tubes in a greenhouse and artificially inoculated with C. quercuum from five different sou...
