This wheat cultivar has wide adaptation, low plant height, a short cycle, good industrial quality, and a mean grain yield of 2,288, 2,745 and 3,944 kg ha'! in the regions 6 (North), 7 (Central West) and 8 (Central South) of the state of Parand, respectively. Key words: crop breeding, wheat, CD 113 INTRODUCTION The increase in production area and yield of wheat is extremely important to supply part of the internal consumption of wheat. However, in the medium and long term self-catering is the overall goal, which re-orientates the crop breeding towards the development of cultivars of wide adaptation and high grain yield potential for different regions in Brazil. According to Destro and Montalvan (1999), the definition of agronomic target traits to be improved is indispensable for the success of a crop breeding program. In this sense, the wheat breeding program of COODETEC focuses on the development of cultivars for the main wheat-producing regions of Brazil. CD 113 was indicated for cultivation in these regions in view of its wide adaptation, high grain yield potential, short cycle, and good industrial quality. PEDIGREE AND BREEDING METHODS CD 113 was developed by the wheat breeding program of COODETEC (Figure 1). F, seeds were obtained by crossing parents EMBRAPA 27 and OC 946. The F,, F3, and F, populations were subjected to modified mass selection, which consisted in the selection of the best plants whose seeds were mixed and used to establish the next generation. The F; and F; populations in turn underwent selection by the pedigree method, which consisted in the selection of plants whose seeds were used in the establishment of a new population in the following generation (pedigree CO13712-00P-00P-13P-0P). The F; populations were selected by the mass method, which gave rise to several lines. Amongst these, selection identified the line that originated the new cultivar CD 113. PERFORMANCE After a preliminary evaluation, trials to determine the Value for Cultivation and Use (VCU) were realized in2001, 2002 and 2003, at different sites and in various !

Regions of adaptation for trials that determine the Value for Cultivation and Use (VCU) periods in the adaptation regions 6 (North), 7 (Central West) and 8 (Central South) of the state of Paraná (Figure 2), under the acronym CD 200113. The VCU trials had a randomized block design with three replications. The 25 treatments were sown on six-row plots in 0.2 cm spacing, 5 m long, totaling 6 m?. Grain yield in the regions 6, 7 and 8 of the state of Paraná attained 6%, 4% and 9% higher values than the control means, respectively, in the three regions (Table 1). The good performance of the new cultivar CD 113 indicated it for cultivation in the wheat-growing regions 6, 7 and 8 of the state of Parana (RCCSBPT, 2005), and it was registered in the Servigo Nacional de Prote¢do de Cultivares do Ministério da Agricultura, index nr. 00552, on February 18, 2004 (MAPA, 2005). In 2005, the indication of cultivation was extended to the regions 1, 2 and 3 of the state of Rio Grande do Sul, 4 and 5 of Santa Catarina, 9 and 10 of Mato Grosso do Sul, 11 and 12 of São Paulo, 13 of Minas Gerais, 14 and 15 of Goiás and 16 of Mato Grosso (Figure 2). OTHERTRAITS The new cultivar CD 113 presented means that classified it as moderately lodging resistant, moderately susceptible to pre-harvest sprouting and moderately tolerant to soil aluminum toxicity. The plant height of the new cultivar CD 113 is low, varying from 55 to 75 cm, and the cycle is early, between 46 and 70 days from emergence to flowering and 95 to 131 days from emergence to maturation (Table 2). The means of these traits were 66 cm, 60 days and 118 days, respectively, which vary with climate conditions, sowing seasons and soil type. The results of analysis of industrial quality, in 7 samples of experimentation in the state, attained in the mean 260 of general gluten strength (W), which includes CD 113 in the group of bread wheat cultivars, with a mean hectoliter weight of 77 kg.hL"!

The field experiments realized between 1999 and 2003 compiled data of different diseases in Brazil. Medium to high severity of powdery mildew (Erysiphe graminis tritici) attack was observed, expressing susceptibility. The cultivar was further susceptible to head blight (Fusarium graminearun), spot blotch (Bipolaris sorokiniana) and speckled leaf blotch (Septoria tritici and S. Nodorum). Severity indices of leaf spot and glume blotch were determined, which classified the new cultivar as moderately susceptible (Table 2). According to Reis etal. (2001) leaf rust (Puccinia recondita f. Sp. Tritici) is considered the most common disease of wheat. In the field evaluations the mean severity was low, suggesting that the new cultivar is moderately resistant (Table 2). The new cultivar CD 113 was classified as moderately resistant to wheat mosaic virus. This virus occurs, according to Reis et al. (2001), especially in the colder regions of Rio Grande do Sul and the Campos Gerais region of Parana. The strong points of the new cultivar CD 113 are the high grain yield potential, broad adaptation, short cycle and good industrial quality (Franco etal. 2004). SEED MAINTENANCE AND DISTRIBUTION COODETEC (BR 467 - km 98 - Caixa Postal 301 - CEP.85813-450 - Cascavel/PR, Brazil) is licenser of protected cultivars according to law nr. 9456/97. The institution contracts seed companies for the multi- plication and trade. Besides, regional represen-tatives work, under the supervision of specific administration, to promote seed commercialization and diffusion.
