The objective of this study was to select Pinus kesya progenies by the estimation of genetic parameters using the method of restricted maximum likelihood (Reml) and prediction of additive genetic values by the best linear unbiased prediction (Blup). The Pinus kesya progeny test was installed in randomized blocks, which consisted of 30 progenies and three replications. The twenty-year-old trees ...

Three genetically hybrid F1 progenies produced between a clinical isolate of Arthroderma simii (KMU4810) and a tester strain of A. vanbreuseghemii (RV27961) were crossed with two tester strains of A. vanbreuseghemii (RV27961 and RV27960) and a tester strain of A. benhamiae (RV30001), respectively. Three crossings yielded hybrid second progenies. Another interspecies crossing between A. simii (K...

A significant protection provided by maternal antibodies against avian adenovirus serotypes 8 and 11, previously associated with the inclusion body hepatitis and hydropericardium syndrome, was observed in breeder progenies after challenge at 1 and 7 days of age. At two weeks of age, in the presence of low maternal antibodies against avian adenovirus (AAV), chicken anemia virus (CAV) and infecti...

A large proportion of mutants with altered pigment features have been obtained via exposure to heavy-ion beams, a technique that is efficient for trait improvement in the breeding of plants and algae. However, little is known about the underlying mechanisms by which the photosynthetic pigments are altered by heavy-ion irradiation. In our study, the photosynthetic characteristics of progenies fr...

Assessing the parental genetic differences and their subsequent prediction of progeny performance is an important first step to assure the efficiency of any breeding program. In this study, we estimate the genetic divergence in Eucalyptus camaldulensis based on the morphological traits of 132 progenies grown in a savanna biome. Thus, a field experiment was performed using a randomized block des...

The aim of this study was to identify inbred progenies of S0:1 maize (Zea mays L.) plants that were efficient at a low level of technology and responsive at a high level of technology through the use of topcrosses. Two contrasting environments were created using two levels of base fertilization and topdressing, so that the levels of nitrogen, phosphorus, and potassium were applied four times hi...

4-97 ABSTRACT Ploidy in various generic Lolium Festuca progenies were assessed by flow cytometry and compared to conventional chromosome counting. In non-segregating triploid and tetraploid progenies, the cytometer estimated so accurately the level of plant ploidy that chromosomes counting would be no use. In segregant progenies, all the tetraploid plants according to the cytometer had effectiv...

An experiment was carried out to compare half-sib and full-sib progeny selection methods in Indian mustard (Brassica juncea L.) under rainfed conditions from 2006-07 to 2009-10 for 14 morpho-physiological characters. Full-sib and half-sib progenies were developed from different populations. The values of genetic parameters were higher in full-sibs compared to half-sibs for a greater number of t...

In D. affinis "sex ratio" (sr), a form of meiotic drive characterized by the production of mostly or only female progeny by certain males, is associated with two different X chromosome sequences, XS-I XL-II and XS-II XL-IV. The behavior of the two sequences differed, depending on the Y chromosome constitution, being either Y(L) or 0. Males with sequence XS-II XL-IV and Y(L) produced progenies w...

About 70% of the rain-fed lowland rice farms in Nigeria are prone to seasonal flooding, which is a major constraint to rice production in some major rice producing areas. Each year that there is flooding, rice farmers in these parts of the country lose their entire crop. This research focuses on developing a submergence tolerant rice variety to overcome crop loss due to flooding. A study of the...
