| Este trabalho teve como objetivo estimar a capacidade combinatória e a depressão endogâmica de híbridos de milho para caracteres agronômicos e qualidade de forragem. Foram avaliados nove híbridos de milho, 36 combinações F1 oriundas de um dialelo, nove populações S1 e duas testemunhas, em dois experimentos delineados em blocos completos ao acaso com três repetições, nas safras 2009/2010 e 2010/2011. Os genitores Impacto, CD304 e DKB390 são recomendados para a formação de um composto a ser submetido a um programa de seleção recorrente visando à melhoria na produção de forragem. Os cruzamentos entre o genitor Impacto e os parentais DKB390, P30P34 e P30B39 são promissores à melhoria da qualidade da forragem por meio da redução nos teores de fibra e aumento de... |

| Abstract: The objective of this work was to compare distributions for the modeling of the number and dry matter weight of nodules (DWN) of Rhizobium from different inoculants in common bean (Phaseolus vulgaris) inbred lines subjected to nitrogen doses, as well as to identify the best inoculant for those lines. The experiment was carried out in a randomized complete block design, arranged in split-split plots, with three factors - four inbred lines, five nitrogen doses (0, 20, 40, 60, and 80 kg ha-1), and three inoculants (CIAT 899, UFLA 02-100, and peat) - and four replicates. The number of nodules and their dry matter weight were analyzed with the generalized linear mixed modeling approach. The highest number of nodules was obtained with the CIAT 899... |

| ABSTRACT: This study aimed to evaluate the inbreeding depression and average genetic components in seven hybrids and two open pollinated cultivars for green corn production, as well as to select the best genotypes in order to obtain base populations for inbred lines extraction. The experiment was carried out in a randomized complete block design with four replications, in a split plot design, with inbreeding levels arranged in the plots and the different genotypes distributed over the subplots, in the municipality of Sabáudia - PR, during the 2014/15 crop season. Higher values of dominance and inbreeding depression were observed for yield of both unhusked and commercial ears. Higher additive effects were detected on length and diameter of commercial ears.... |
