SUMMARYA total of 245 test cross progenies obtained by crossing cytoplasmic male sterile (CMS) lines and restorer (RHA) lines were evaluated in replicated trials in 1995 and 1997. Experiments were carried out in two locations (Osimo, East Central Italy and Budrio, Northern Italy) in 1995, whereas in 1997 trials were conducted only in Osimo. General combining ability (GCA) and specific combining ability (SCA) of the parents was evaluated to identify genotypes suitable to be used as testers for breeding programs and to verify the performance of hybrids. The results obtained in 1995 were used to make test crosses in 1996 to be evaluated in 1997. The GCA and SCA of RHA and CMS lines were nearly always significant for all the studied traits when lines were randomly taken in 1995. When selected testers were used on the basis of the results of the first year, the SCA of new RHA lines and GCA of new CMS lines were not significant for achene yield, but they were for the other traits.The best GCA estimates for RHA were often higher than those of CMS, indicating that selection for RHA could be more useful than for CMS. As expected, GCA was always lower than SCA. CMS and RHA, with high variance among their test crosses for yield and many other traits, could be used as testers. The lack of a tester with high variance in all traits requires more than one tester in evaluating lines. The GCA of a line can change in function of the germplasm with which it is combined.

Heterosis occurred for the eight plant and seed characters studied. It was most frequent for yield of seed and height of plant. Mean squares for general combining ability (gca) and specific combining ability (sca) were significant (P =.01) for all characters. The estimated components for gca were greater than for sca for days to mature, weight per bushel, and percent oil in the seed; less for height and yield of seed; and essentially the same for days to bloom, diameter of head, and weight per 1000 seeds.The yield of seed and percent oil in the seed, for the highest ranking 100 synthetics that could be composed from the 10 lines, was predicted in F6 assuming 50 and 60% outcrossing between F2 and F6. Virtually all values exceeded the mean performance of four check samples of commercial hybrids. Many exceeded the highest rank check for oil content in the seed. Fourteen of the highest ranking 100 synthetics for yield and 30 for oil content consisted of two or three lines. It was concluded that synthetics can be superior to the present hybrids in heterosis and that desirable synthetics can be made from only a few lines.

O objetivo do trabalho foi avaliar a prensagem a frio a partir das amêndoas de girassol alto oleico (AO) para obtenção de óleo extra virgem, biodiesel etílico e farinha proteica. A caracterização química foi realizada utilizando métodos oficiais de análise. O óleo foi extraído utilizando uma prensa helicoidal contínua e obteve-se um rendimento de 40%. O biodiesel etílico foi produzido por reação de transesterificação obtendo-se alto teor de ésteres etílicos (99,2%). Com a remoção total das cascas foi possível produzir um farelo com elevado teor de proteínas (51,6% b.s.). A composição mineral dos grãos, das amêndoas e das cascas de girassol mostrou que nos grãos os elementos de maior incidência foram Fe, Cr e Ni; nas amêndoas S, P, Mg, Cu, Mn e Zn e nas cascas Ca, K, Al, Ba, Sr e Na. Todos parâmetros de qualidade avaliados para o óleo, farinha e biodiesel etílico estão de acordo com a legislação indicando alta qualidade do óleo extra virgem e estabilidade termo-oxidativa, não sendo necessário o seu refino. A prensagem a frio das amêndoas, com ausência total de cascas, permitiu obter coprodutos de alta qualidade para aplicação na indústria alimentícia (óleo extra virgem e farinha proteica) e energética sustentável (cascas e biodiesel).PALAVRAS-CHAVE: Helianthus annuus L., estabilidade termo-oxidativa, composição química, minerais, transesterificação. OBTAINING OIL, FLOUR AND ETHYLIC BIODIESEL FROM COLD PRESSING OF HIGH OLEIC SUNFLOWER KERNELSABSTRACT: The objective of this work was to evaluate the cold pressing from high oleic (HO) sunflower kernels to obtain extra virgin oil, ethylic biodiesel and protein flour. The chemical characterization was performed using official methods of analysis. The oil was extracted using a continuous screw press and the yield was 40%. Ethylic biodiesel was produced by transesterification reaction obtaining a high content of ethyl esters (99.2%). With the total removal of the hulls, it was possible to produce a meal with 51.6% proteins. The mineral composition of the grains, kernels and hulls showed that in the grains the elements of higher incidence were Fe, Cr and Ni; in the kernel were S, P, Mg, Cu, Mn and Zn and in the hulls were Ca, K, Al, Ba, Sr and Na. All quality parameters evaluated for oil, flour and ethylic biodiesel were in accordance with the legislation and indicated high quality and thermo-oxidative stability in extra virgin oil, with no necessity of refining. The removal of the hulls and the cold pressing of the kernels provide the production of high quality co-products for use in the food industry (extra virgin oil and protein flour) and sustainable energy (hulls and biodiesel).KEYWORDS: Helianthus annuus L., oxidative stability, chemical composition, minerals, transesterification.
