Sample sizes to estimate mean values for tassel traits in maize genotypes.
Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize genotypes and to verify the variability of sample size among genotyp...
متن کاملSample Sizes To Estimate Proportions And Correlation
Very often statisticians have to deal with the problem of sample size calculation. However this is one of the most difficult questions to be answered since it depends on many considerations, assumptions and restrictions on the real problem being solved. In this paper we develop some methods, based on credible intervals, to calculate sample sizes for proportions and correlations.
متن کاملOptimum Block Size in Separate Block Bootstrap to Estimate the Variance of Sample Mean for Lattice Data
The statistical analysis of spatial data is usually done under Gaussian assumption for the underlying random field model. When this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. One of the crucial problems in this setting is specifying the block sizes. In this paper, we present asymptotic optimal block size for separate block bootstrap to estimate the...
متن کاملA Methodology to Estimate Ores Work Index Values, Using Miduk Copper Mine Sample
It is always attempted to reduce the costs of comminution in mineral processing plants. One of thedifficulties in size reduction section is not to be designed properly. The key factor to design size reductionunits such as crushers and grinding mills, is ore’s work index. The work index, wi, presents the oregrindability, and is used in Bond formula to calculate the required energy. Bond has defi...
متن کاملEstimation of the breeding value of morphophysiological traits of maize (Zea mays L.) genotypes using BLUP method
Knowledge of genes action on important traits and their breeding value is necessary to achieve high yielding cultivars in food crops. Molecular markers has eliminated the need for knowing the pedigree of genotypes for estimating Kiniship matrix required to estimate breeding values of taits of interest. In this research, 97 genotypes of maize were evaluated for 17 different agronomic triats usin...
