In a field trial involving 68 rubber tree (Hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth A and for age 7 to 12 ...

This study aimed to estimate genetic parameters and correlations between traits of agronomic interest in a soybean population, to select traits for use in crop breeding. Thus, we analyzed 28 soybean genotypes in randomized ...

This study aimed to estimate genetic parameters and genetic trends for reproductive traits and testicular growth in Guzera cattle. Variance components were estimated through two-trait analyses using the restricted maximum ...

The internal genetic structure and outcrossing rate of a population of Araucaria angustifolia (Bert.) O. Kuntze were investigated using 16 allozyme loci. Estimates of the mean number of alleles per loci (1.6), percentage ...

In beef cattle, growth, reproductive, and carcass traits have been studied for improving productivity and quality of meat products. The aim of this study was to estimate genetic parameters for birth (BW), weaning (WW) and ...

The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT ...

The objective of this study was to evaluate the association of visual scores of body structure, precocity and muscularity with production (body weight at 18 months and average daily gain) and reproductive (scrotal ...
