ABSTRACT.
Leaf rust (caused by Puccinia triticina Eriks.) is an important disease of wheat (Triticum aestivum L.) in Uruguay; therefore breeding for resistance to this disease has been a long-term objective for the INIA wheat-breeding program. Information on the identity of resistance genes present in the program is required to design strategies to breed for effective and more durable resistance. The leaf rust resistance genes present in seven adapted cultivars that have been extensively used in crosses were studied. Races of Puccinia triticina with different virulence combinations were used to determine which seedling resistance genes may be present in six cultivars. Genetic analysis of seedling and adult plant resistance (APR) was conducted on BC1F2 and F3 generations from four cultivars crossed with the susceptible cultivar Thatcher. The cultivar Estanzuela Tarariras was postulated
to have Lr3bg and genetically determined to have Lr13 and Lr34; INIA Boyero was postulated to have Lr26 and genetically determined to have Lr13 and Lr34; Estanzuela Benteveo was postulated to have Lr3a and Lr26 and genetically determined to have Lr13. Estanzuela Pelón 90 was postulated to have Lr1, Lr17a, and Lr26 and genetically determined to have Lr34; INIA Caburé was postulated to have Lr24; INIA Churrinche was postulated to have Lr10 and Lr24; and INIA Tero was postulated to have Lr17a and Lr24. INIA Boyero and Estanzuela Benteveo carry additional APR gene(s) that might be useful sources of resistance in addition to Lr34. MenosABSTRACT.

Forestry in Uruguay has grown exponentially for the last 20 years. Even though plantations of Eucalyptus L?Hér. account for about 80% of the total forested area in the country, pine tree plantations are relevant in the production of high quality timber. Following the introduction of pine in 1810, large scale production of pine tree plantations
started in 1940, mainly with Pinus radiata Don (Pinaceae) (Porcile 2007). In 1950, seeds of Pinus taeda L. and Pinus elliottii Engelm., among others, were brought from the United States. To date, pine tree plantations occupy 20% of the forested area in the country (250,000 ha mainly in the northern part of the country), mostly with
P. taeda and P. elliottii (MGAP 2012). In December 2009, an infestation of bark beetles was officially reported by one of us to The Ministry of Livestock, Agriculture and Fishery. The outbreak was compounded by three species. |
