five genotypes of chickpea as a half diallel crossed with each other, in 2008, 5 parents and 10 progenies were planted as randomized complete block design and some traits including days to podding, basal pod height, number of pods per plant, number of double seed pods per plant, number of single seed pods per plant, number of empty pods per plant, seeds per plant and seed yield per plant were e...

Diallel mating is a frequently used design for estimating the additive and dominance genetic (polygenic) effects involved in quantitative traits observed in the half- and full-sib progenies generated in plant breeding programmes. Gibbs sampling has been used for making statistical inferences for a mixed-inheritance model (MIM) that includes both major genes and polygenes. However, using this ap...

The susceptibility to Brugia malayi infections of F2 and F4 progenies of Aedes aegypti (Black Eye strain) treated with ethyl methanesulfonate (EMS) was tested. Both 3-day-old males and females were treated with 0.025, 0.050, 0.075 and 0.10% EMS. Control and treated females were then mated with normal or treated males to recover F1 progeny. F2 offspring were derived from sibling intercrosses, an...

Inbred strains generated from native and exotic pigs were compared with their F1and f2 backcross populations for a range of litter size performance traits. Animals were intensively reared and at 81⁄2 months of age, the inbred genotypes from each strain were reciprocally mated to each other to generate F1 crossbred genotypes; while gilts from each crossbred group were backcrossed to their male p...

Peanut is a major oilseed crop worldwide. In the Brazilian peanut production, silvering thrips and red necked peanut worm are the most threatening pests. Resistant varieties are considered an alternative to pest control. Many wild diploid Arachis species have shown resistance to these pests, and these can be used in peanut breeding by obtaining hybrid of A and B genomes and subsequent polyploid...

Reproductive failure of rising-two-year-old (R(2)) hinds and seasonal misalignment between calving and pastoral feed production are two factors limiting reproductive productivity of farmed red deer hinds in New Zealand. This study aimed to better understand processes around female puberty and breeding seasonality by describing the potential breeding season (i.e., oestrous cyclicity) of three re...

We have attempted to estimate the number of genes involved in postzygotic reproductive isolation between two closely related species, Drosophila simulans and Drosophila sechellia, by a novel approach that involves the use of high resolution two-dimensional gel electrophoresis (2DE) to examine testis proteins in parents, hybrids and fertile and sterile backcross progenies. The important results ...

This study was conducted to evaluate growth performance, brooding and rearing mortalities of F2 main reciprocal backcross progenies Abor Acre broiler breeder x native chicken crosses compare their F1 progenies. The base population used in the consisted mature (~ 48 weeks) male female chickens exotic (Abor Acre) parent stock. varieties were made up normal feather, naked neck frizzle genotypes. T...

Mungbean (Vigna radiata) is an important short-season legume widely cultivated in Asia, particularly India. It highly susceptible to bruchids and developing bruchid resistance goal mungbean breeding programs. In the present study, 52 genotypes were evaluated for based on “no-choice test” identified two resistant (V2802BG V2709) with no adult emergence seed damage. Further, these crossed six hig...
