Identification of superior soybean lines by assessing genetic parameters and path analysis of grain yield components
This study estimated genetic parameters, identified traits of direct and indirect correlation with the grain yield through path analysis and select superior lines, maximizing genetic gain. Two experiments were conducted in 2012/2013 season in randomized blocks with three replications. 23 lines (experiment I) and 44 lines (experiment II) were seeded. For all traits analyzed in both experiments, there was a significant...

Evaluation of some biological activities of Euglena gracilis biomass produced by a fed-batch culture with some crop fertilizers
The feasibility of growing Euglena gracilis in some crop fertilizers was investigated and some biological activities of the produced biomass were evaluated. A fed-batch mixotrophic culture was done in an airlift photobioreactor operated at an aeration rate of 0.2 vvm. A final biomass concentration of 2.6 gL-1 obtained with NPK15:15:15 after 96 h of cultivation was significantly lower than the 5.7 gL-1 obtained with BGII...

Genetic diversity and population structure of traditional sweet cassava accessions from Southern of Minas Gerais State, Brazil, using microsatellite markers
Sweet cassava is a food culture of great importance because it is a source of nutrition and energy for millions of people in tropical and sub-tropical regions. For that reason, genetic diversity and population structure studies are necessary in order to obtain more information regarding the evaluated genotypes, reassuring their use in future breeding programs. The objective of this study was to evaluate the genetic...

Effect of mineral salts and nitrogen source on yeast (Candida utilis NOY1) biomass production using tubers wastes
The deficiency of protein in human food and animal feed is well recognized due to the rapid growth of population. It is therefore, important to increase protein production by utilizing all the available ways and means. In the light of this, an attempt was made in this study by selecting Candida utilis NOY1. This yeast was used to determine the optimum concentration of different minerals salts and nitrogen source on...

Blood biochemical profile of Sudanese crossbred repeat breeder cows
Repeat breeder (RB) is a cow that fails to conceive from three or more successive insemination, but with normal estrus and absence of detectable clinical abnormalities. It is one of the major problems in dairy production. In the present study, the plasma biochemistry of Sudanese crossbred RB cows was examined. Plasma glucose, total cholesterol (TC), triacylglycerol (TG), total protein (TP) and urea nitrogen were...

Hybrids performance of doubled haploid lines derived from 10 tropical bi-parental maize populations evaluated in contrasting environments in Kenya
The doubled haploid (DH) technology enables maize breeders to develop a large number of homozygous lines rapidly and test them in hybrid combinations early in the breeding cycle. The objectives of this study were to evaluate testcross performance of 556 DH lines derived from 10 diverse tropical backcross (BC1) populations, and to estimate variance components and broad-sense heritability under both well-watered and...
