“…(M= measurements; R= repetition; B= blocks; G= genotypes). Diamantina, UFVJM, 2017. phenotypic variation observed was influenced by the environment, in other words, controlled by several genes (Lira Júnior et al, 2014). Vieira et al (2017), studying different strawberry cultivars in Lavras-MG, found heritability values for MMFT (75.66%) above this study, which shows that, besides being different genetic materials, the environment itself interferes in the expression of the characteristics.…”

The estimation of repeatability coefficient provides support to define the number and the appropriate period of genotype evaluations, obtaining better success in breeding programs, in order to lower labor costs. Therefore, knowing repeatability and heritability parameters is relevant. Thus, the aim of this study was to estimate the repeatability and heritability coefficients and accurately determine the number of measurements. Eight strawberry cultivars were analyzed in a randomized block design with four replicates and eighteen plants per plot, being harvested twice a week over a period of six months (May to October, 2012), totalizing six evaluations. Among the evaluated traits, the estimated heritabilities ranged from 3.13% (number of fruits) to 40.20% (average fruit mass) whereas the repeatability ranged from 9.00 to 42.06% for the same characters. The minimum number of evaluations, to reach a coefficient of determination with an accuracy of about 80%, ranged from the maximum of 40 for fruit number and the minimum of 6 for average fruit mass. In order to be considered commercially important marketable fruit mass, minimum of 20 evaluations are required, it means, at least, 20 months.

“…When a genotype is selected for commercial cultivation, it is expected to maintain its superior or aboveaverage initial performance throughout its productive life. This expectation can be confirmed by estimating the repeatability coefficient of relevant traits for agro-industry (Lira Júnior et al 2014).…”

Repeatability of biometric and fruit and seed yield traits of sacha inchi

et al. 2017

Repeatability allows an estimation of the number of evaluations needed to optimize the selection of superior genotypes, with consequent effects on the research costs in terms of financial and human resources. The objective of this study was to estimate the coefficient of repeatability of biometric and yield traits, related to fruits and seeds of sacha inchi (Plukenetia volubilis), and to define the number of evaluations required for an efficient selection and evaluation of genotypes of the species. A total of 37 non-domesticated accessions were evaluated for 19 months in a randomized block design with 5 replications and 2 plants per plot. The total number of fruits, total number of seeds, total fruit weight, mean fruit weight, and number of seeds per fruit of the accessions were evaluated by monthly sampling. Additionally, seed biometry was assessed in a sample of 30 seeds per accession. Repeatability coefficients were estimated by analysis of variance, principal components and structural analysis. The principal component method based on the covariance matrix was the most appropriate for establishing repeatability estimates of sacha inchi, due to the cyclical nature of the crop. Superior genotypes of the species can be selected for yield-related traits with about 90% accuracy, from 5 harvests (months) onwards. To ensure this accuracy level, it would be necessary to evaluate a minimum of 5 and 25 fruits to determine mean fruit weight and number of seeds per fruit, respectively, and 39 seeds would be required to evaluate the biometric traits.

The serigueleira is a fruit that is little explored commercially in several regions of Brazil, having little work regarding the feasibility of seedling production by cuttings with and without plant regulators. Due to this lack of technical information, the present work has as main objective to evaluate the rooting of herbaceous and woody cuttings of the serigueleira (Spondias purpurea L.) treated with indolbutyric acid (AIB). Herbaceous and woody cuttings were obtained from a matrix plant with approximately fifteen years of age, with 12 cm in length the cuttings were cut in bevel and then immersed in a commercial fungicide solution of 0.2%. The cuttings were treated with AIB in the form of talc, 0, 1%, 2%, 3% and 5%, planted in beds containing vermiculite, rice straw and construction sand. The experimental design used was completely randomized, with four replications, each plot consisting of 10 cuttings. Cuttings were evaluated over 90 days, recording the following parameters: percentage of rooted cuttings, percentage of live cuttings and calluses, number of cuttings with buds, average length of the largest root and number of roots. Among the results obtained, the best concentration was 3% of 5% IBA in the rooting of herbaceous cuttings (17,25% in 17,75%) and 5% of IBA in the rooting of woody cuttings (22,25% e 22,55%). Herbaceous cuttings showed higher percentages of cuttings with calluses when compared to woody cuttings.
