Genetic study of meat quality traits in a male broiler line
Age-age correlation for early selection of rubber tree genotypes in São Paulo State, Brazil
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 ...
ESTIMATES OF GENETIC PARAMETERS AND CORRELATIONS BETWEEN MORPHOLOGICAL TRAITS IN SOYBEAN GENOTYPES
(Univ Federal Mato Grosso, 2015-10-01)
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 ...
GENETIC PARAMETERS AND GENETIC TRENDS FOR TESTICULAR GROWTH AND REPRODUCTIVE TRAITS IN GUZERA CATTLE
(Univ Fed Rural Semi-arido-ufersa, 2015-01-01)
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 ...
Internal genetic structure and outcrossing rate in a natural population of Araucaria angustifolia (Bert.) O. Kuntze
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 ...
Genetic analyses on bodyweight, reproductive, and carcass traits in composite beef cattle
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 ...
Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
(Univ Sao Paolo, 2014-07-01)
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 ...
Estimates of genetic parameters for visual scores and their correlation with production and reproductive traits in Brahman cattle
(Sociedade Brasileira de Zootecnia, 2012-06-01)
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 ...
Genetic parameters estimates for milk, fat and protein yield analyzed by test day models for Murrah buffaloes in Brazil
(Pagepress Publ, 2007-01-01)
The objectives of this study were to estimate genetic parameters for test-day milk, fat and protein yields, in Murrah buffaloes. In this study 4,757 complete lactations of Murrah buffaloes were analyzed. The (co) variance ...
Genetic parameters for milk yield, lactation length and calving intervals of murrah buffaloes from brazil
The major objective of this study was to estimate heritability and genetic correlations between milk yield (MY) and calving interval (CI) and lactation length (LL) in Murrah buffaloes using Bayesian inference. The database ...
