line g-14088 was first introduce in iran together with 60 other chitti bean lines in 1988 through ciat. it was tested in different breeding experiments for yield and agronomic characteristics and was compared with local cultivar checks and other advanced lines of chiti bean from 1988 to 2005 in different locations of iran. due to higher seed yield and favorable characteristics, it was selected ...

For an organized cross breeding program, information on heterotic grouping, perse performance, and commercial heterosis of newly introduced maize lines is required. Therefore, the present study was conducted to determine group, heterosis, crosses mean performance from IITA-Nigeria CIMMYT- Zimbabwe quality protein inbred lines. 36F1 progenies generated four testers nine lines, including standard...

Attempts to conserve threatened species by establishing new populations via reintroduction are controversial. Theory predicts that genetic bottlenecks result in increased mating between relatives and inbreeding depression. However, few studies of wild sourced reintroductions have carefully examined these genetic consequences. Our study assesses inbreeding and inbreeding depression in a free-liv...

Genetic and Phenotypic Effects Inbreeding can have dramatic effects on a herd. These effects are the result of individuals receiving identical genes from each parent. If the parents are related, it is more likely that they have genes that are identical. An individual receiving identical genes from each parent is said to be homozygous for that pair of genes. This would be desirable if the gene t...

Tree breeders use traits of economic interest as productivity, stem form and wood quality, to select individuals for advanced generations. We determined the genetic control growth volume, tree height diameter, resistance, calculated a selection index Pinus maximinoi P. tecunumanii, selected were used establish seedling seed orchard (SSO). The largest gain obtained in SSO was 21.48% while tecunu...

Pronounced additive genetic variation and high narrow-sense heritability for lesion length caused by Neonectria neomacrospora were found in a Nordmann fir progeny test. Significant inbreeding depression was detected traits important Christmas tree production. Recurrent selection multiple would be successful quality traits. The fungal pathogen N. causes severe damage trees Denmark. Family diseas...

Computer mating programs have helped breeders minimize pedigree inbreeding and avoid recessive defects by mating animals with parents that have fewer common ancestors. With genomic selection, breed associations, AI organizations, and on-farm software providers could use new programs to minimize genomic inbreeding by comparing genotypes of potential mates. Relationships could be computed between...

The effectiveness d selection for 3-9-week gain was examined in a population of rats with a history of past selection for high 3-9-week gain. Lines were selected for high (U line) and low (D line) 3-9-week gain with two replicates of each line. Two randomly selected lines were also kept, one originating from the same base population as the two selected lines (R line) and the other originating f...

low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...
