The mixed-model methodology is an alternative to select genotypes for traits highly influenced by the environment. In addition, this method allows FOR estimating the repeatability coefficient and predicting the number of assessments needed for a selection process to increase reliability. This study aimed to determine the minimum number of evaluations necessary for a reliable selection process and to estimate the variance components used for predicting genetic gains between and within half-sib families of elephant grass (Cenchrus purpureus (Schumach.) Morrone) using the mixed-model methodology. Half-sib families were generated using genotypes from the Active Germplasm Bank of Elephant Grass. The experiment was performed in a randomized block design with nine half-sib families, three replicates, and eight plants per plot. We evaluated 216 genotypes (individual plants) of elephant grass. The deviance analysis was carried out, genetic parameters were estimated, gains between and within families were predicted, and repeatability coefficients were obtained using Selegen software. There was genetic variability for selection within the families evaluated. The reliability values found above 60 % for plant height and number of tillers and above 80 % for dry matter yield suggest that only two evaluations are required to select superior genotypes with outstanding reliability. Sixteen genotypes were identified and selected for their productive potential, which can be used as parents in elephant grass breeding programs for bioenergy production.

The objective of this study was to evaluate the efficiency of pre-harvest application of 1-methylcyclopropene?-cyclodextrin in concentrated magnesium sulfate solution (1-MCP; Harvista? 1.3 SC) to delay maturation of ?Cripps Pink? apple fruit. 1-MCP was sprayed at 0, 75, 150, 225 and 300 mg L? 1 , seven days before the anticipated harvest time (DBAH). Aminoethoxyvinylglycine (AVG, 124 mg L? 1 , Retain®) was sprayed 28 DBAH, as a commercial control treatment. Fruit maturation was delayed by increasing 1-MCP concentration. 1-MCP at concentrations ? 150 mg L? 1 delayed by six and 15 days the time for the fruit to reach the harvest firmness of 71.1 N and 66.7 N, respectively, compared to untreated fruit. Skin color changes (red color development and background degreening) were inhibited by increasing 1-MCP concentrations up to 300 mg L? 1 . The reduction of ethylene synthesis, and the loss of flesh firmness and starch content occurred by increasing 1-MCP concentrations up to 98.2, 134.5 and 182.3 mg L? 1 , respectively. The AVG treatment delayed ethylene production and skin red color development at harvest more markedly than the highest concentration of 1-MCP (300 mg L? 1 ). However, both treatments (AVG and 1-MCP at 300 mg L? 1 ) had late harvested fruit (28 days after spraying 1-MCP) with percentage of skin red color below 40%. The results show that 1-MCP delays maturity, but concentrations ?135 mg L? 1 do not improve its efficacy on preserving flesh firmness while might inhibit skin red color development in ?Cripps Pink? apples.
