In this study production, reproduction, population, management and economic parameters resulted from recording of 7 flocks with size 57 to 400 and 721 heads of camels in a cycle of reproduction, during three years from 2011 to 2013 were used to find out of the economic values of important traits in one hump camel in desert areas rearing system. The economic traits that appeared in profit equati...

Genetic improvement of pig performance is a primary tool in enhancing profitability in pig enterprises. The first step of genetically improving livestock is the development of a breeding objective which combines all economically important traits that can be improved by selection. These traits are given economic values that are defined as the increase in profit with a single unit change in each ...

Brinjal eggplant (Solanum melongena L.) is an agronomically important nontuberous crop of Solanaceae family, native to southern India, and widely grown in Americas, Europe and Asia. Its close relatives: S. aethiopicum (scarlet eggplant) and S. macrocarpon (Gboma eggplant) are of African origin. Brinjal eggplant is a new vegetable in Poland. Until recently it was grown only in glasshouse conditi...

We intuitively believe that the dramatic drop in the cost of DNA marker information we have experienced should have immediate benefits in accelerating the delivery of crop varieties with improved yield, quality and biotic and abiotic stress tolerance. But these traits are complex and affected by many genes, each with small effect. Traditional marker-assisted selection has been ineffective for s...

INTRODUCTION Beef breeding programmes have developed significantly in the last 24 years since the 1 WCGALP. Breeding programs as defined here include the definition of breeding objectives, recording and genetic evaluation programs to develop selection criteria and developments in selection and mating technology to optimize genetic progress for the objective. Available today are tools for the im...

2 0 Prediction of single-cross hybrid performance has been a major goal of plant breeders since the 2 1 beginning of hybrid breeding. Genomic prediction has shown to be a promising approach, but 2 2 only limited studies have examined the accuracy of predicting single cross performance. Most of 2 3 the studies rather focused on predicting top cross performance using single tester to determine 2 ...

Jatropha is a species with great potential for biodiesel production, and the knowledge on how the main agronomic traits are correlated will contribute to its improvement. Therefore, the objectives of this study were to estimate the genetic parameters of the traits: plant height at 12 and 40 months, canopy projection on the row at 12 and 40 months, canopy projection between the row at 12 and 40 ...

The objectives of this study were to estimate the genetic parameters for milk yield unadjusted and adjusted for days in milk and, subsequently, to assess the influence of adjusting for days in milk on sire rank. Complete lactations from 90 or 150 days of lactation to 270 or 350 days in milk were considered in these analyses. Milk yield was adjusted for days in milk by multiplicative correction ...
