“…When the genetic recombination is aimed it is important to know the heritability of the characteristic, since the characteristics which have a higher heritability are easier to carry out the transference from a plant to another as it is also the selection, because the environment has less effect on the expression of the characteristic (HARTWIG et al, 2007).…”

Silage of quality is required by farmers for providing significant increases in productivity and maximizing the profitability of the productive system, being the sunflower crop (Helianthus annuus L.) an option for this purpose. The aim of this review was to discuss aspects about genetic characteristics linked to improvement of the sunflower for the production of whole plant silage. The genetic breeding of sunflower has got proportions after the discovery of cytoplasmic male sterility and of the restoration gene. The sunflower crop presents good forage potential and should be used in addition to corn silage. There are genetic resources for the breeding of the bromatological characteristics of the crop for forage production. As a rustic plant, the sunflower can be grown in regions or seasons which have risk of water shortages, generating income and enhancing the use of the land.Keywords: Bromatological characteristics; heritability, hybrids; lines; cytoplasmic male sterility. Caracteristicas genéticas do girassol (Helianthus annuus L.) visandomelhoramento para silagem de planta inteira ResumoSilagens de qualidade são requeridas pelos agricultores por propiciar significativos incrementos na produtividade e maximizar a rentabilidade do sistema produtivo, sendo a cultura do girassol (Helianthus annuus L.) uma opção para este fim. O objetivo desta revisão foi abordar aspectos sobre características genéticas ligadas ao melhoramento do girassol para produção de silagem de planta inteira. O melhoramento genético do girassol ganhou proporções após a descoberta da macho-esterilidade citoplasmática e do gene de restauração. A cultura do girassol apresenta bom potencial forrageiro, devendo ser utilizada em complemento a silagem de milho. Há recursos genéticos para o melhoramento das características bromatológicas da cultura para a produção de forragem. Por ser uma planta rústica o girassol pode ser cultivado em regiões ou épocas que tem risco de déficit hídrico, gerando renda e potencializando o uso da terra.Palavras chaves: características bromatológicas; herdabilidade; híbridos; linhagens; macha-esterilidade citoplasmática.

The sowing density adjustment in oatcan maximize the productivity expression.The aim of this study is to define the behavior of productivity expression of biomass, grains, straw andharvest indexthrough increasing sowing density in the main biotype cultivated in Southern Brazil. It proposesthe possibility of indicating higher sowing density to the productivity maximization of biomass and grains.With the densityadjusted to the grain productivity to simulate the reflexes on the biological and straw productivity and harvest index compared to recommendeddensity, considering high and reduced tillering cultivars in different succession systems.The study was carried out in 2013, 2014 and 2015 in randomized blockdesign with four replications in a 4 × 2 factorial scheme, for sowing density (100, 200, 300, 600 and 900 m -2 ) and oat cultivars (Brisasul and URS Taura), respectively, in the corn/oat and soybean/oat succession system.With the increase in sowing density, the biological and straw productivity evidence alinear behavior and the grain productivity and harvest index ofquadratic behavior, regardless of the cultivar,agricultural year and succession system. It is possible to indicate a higher sowing density to the biomass and grain productivity maximization with sowing density close to 500 seeds m -2 in the main succession systems.In high and reduced tillering cultivars, the adjusted density compared tothe recommended increasedthe biological and straw productivity, regardless of agricultural year and succession systems.

The use of productive cultivars with adaptability and stability and less demanding to fungicide use are critical to the sustainability of production factors. The objective of this work was to determine the per se performance of white oat cultivars and parameters of adaptability and stability on yield and grain quality in the proposition of cultivars more responsive in reducing the use fungicide. The study was conducted in Augusto Pestana, RS, Brazil, between the years 2010 and 2013. The experimental design was randomized blocks with six replicates, three with and three without fungicide. The study evaluated 14 white oat cultivars for yield and industrial capability. The white oat cultivars FAEM 4 Carlasul and URS Corona indicate high grain yield with stability and general adaptability, independent of chemical control. The cultivar URS Corona shows together high yield and thousand grain weight and hectoliter with general adaptability and stability in the absence of fungicide. Although no stability has been detected in industrial yield without the use of fungicides, cultivars of URS Charrua, URS Corona and URS Taura show high means with general adaptability.
