“…According to these same authors, the number grain per panicle and grain weight per panicle were also effective in differentiating more desirable genotypes. In wheat, observed that the weight spike and the number grains per spike were the variables that contribute most of the observed differences in inflorescence [26].…”

The oat panicle components were changed by the forms of nitrogen use influencing productivity. The aim of the study was to determine the direct and indirect effects of oat panicle components on grain yield by N-fertilizer rates in succession systems of high and reduced release of N-residual. The study was conducted in the years 2013 and 2014 in a randomized complete block with four replications in a factorial 3 × 2, for nitrogen rates (30, 60 and 120 kg•ha −1) and oat cultivars (Barbarasul and Brisasul) the soybean/oat and corn/oat systems. The panicle weight and grain per panicle show greater sensitivity to the change of nitrogen rates. Grain yield was favored by the direct effect of harvest index panicle and indirect by grain weight per panicle. In the system soybean/oat, the grain weight of panicle shows greater efficiency in promoting positive direct effects on grain yield.

Resumo -O objetivo deste trabalho foi estabelecer um padrão para a caracterização molecular e a diferenciação de porta-enxertos de pessegueiro, bem como estimar parâmetros de variabilidade genética com base em marcadores codominantes. Catorze genótipos foram avaliados com uso de iniciadores para locos microssatélites das séries BPPCT e UDP, e para locos STS e SCAR. O perfil eletroforético foi registrado quanto à presença ou à ausência de bandas, as quais foram usadas para calcular a similaridade genética entre cultivares, por meio do coeficiente "simple matching", e para a análise de agrupamento de cultivares, pelo método das médias aritméticas não ponderadas (UPGMA). Foram calculados: número de alelos por loco, frequências alélicas, heterozigosidade esperada e observada, endogamia e conteúdo de informação polimórfica (PIC). Os 18 locos avaliados produziram 82 polimorfismos e permitiram elaborar um dendrograma que discriminou os genótipos em três grupos principais. A heterozigosidade esperada e observada nos 18 locos SSR foi de 0,66 e 0,22, respectivamente. Valores máximos para endogamia (1,0) foram identificados nos locos UDP 98407, UDP 98412, BPPCT 034, BPPCT 016, SCAR-SCAL 19 e STS OPAP4. O PIC variou de 0,81, para SCAR-SCAL 19, a 0,46, para UDP 98407. O polimorfismo dos 18 marcadores possibilita obter acurada relação genética entre os genótipos de pessegueiro avaliados e identificar os mais contrastantes para uso em programas de melhoramento. Termos de indexação: Prunus persica, distância genética, frequência alélica, genética molecular, seleção de parentais. Molecular characterization and genetic variability among peach rootstocks based on codominant markersAbstract -The objective of this work was to establish a standard for molecular characterization and differentiation of peach rootstocks, as well to estimate genetic variability parameters based on codominant markers. Fourteen genotypes were evaluated using primers for microsatellite loci from the BPPCT and UDP series and for the STS and SCAR loci. The electrophoretic profile was recorded for the presence or absence of bands, which were used to calculate the genetic similarity among cultivars by the simple matching coefficient, and to perform cluster analysis by the unweighted arithmetic average (UPGMA) method. The number of alleles per locus, allele frequencies, observed and expected heterozygosity, inbreeding, and polymorphic information content (PIC) were calculated. The 18 loci produced 82 polymorphisms, allowing for the elaboration of a dendrogram, which discriminated the genotypes into three main groups. Observed and expected heterozygosity in the 18 SSR loci were 0.66 and 0.22, respectively. Maximum values for inbreeding (1.0) were identified in loci UDP 98407, UDP 98412, BPPCT 034, BPPCT 016, SCAR-SCAL 19, and STS OPAP4. PIC ranged from 0.81 for SCAR-SCAL 19, to 0.46 for UDP 98407. The polymorphism of the 18 markers allows for an accurate genetic relationship among the evaluated peach genotypes and the identification of the more contrasting ones f...

“…The cluster analysis obtained by Tocher method (Table 3) allowed the separation of the 25 genotypes into eight distinct groups, and group II had the largest number of genotypes, including genotypes of the three fruit color morphotypes (white, black and red). suggesting a good representation of the similarity matrix generated by Jaccard's coefficient (SILVA, 2007). Table 1, and were identified by the color of the ripe fruits.…”
