based on principal component analysis (pca), gge biplot analysis is an effective method to fully assess multienvironmental yield trials (mets). additive main effects and multiplicative interaction (ammi) is an alternative method for assessing phenotypic stability and adaptability. in this research, met data of 14 maize inbred lines were used to perform ammi and gge biplot analyses. these genoty...

since crosses of lines with suitable genetic distance produce excellent hybrids, the identification of genetic diversity between zea mays l. inbred lines in hybrid maize breeding programs has a high priority. a total of 27 inbred lines plus b73 and mo17 (sc704 parents) were evaluated by 15 inter-simple sequence repeat (issr) primers. inbreds were selected randomly from inbred lines from the agr...

Recombinant inbred lines (RILs) can serve as powerful tools for genetic mapping. Recently, members of the Complex Trait Consortium have proposed the development of a large panel of eight-way RILs in the mouse, derived from eight genetically diverse parental strains. Such a panel would be a valuable community resource. The use of such eight-way RILs will require a detailed understanding of the r...

The aim of the research work was to study the genetic variability of sunflower (Heliantus annuus L.) seeds collection. From 1500 available genotypes a set of 120 recombinant inbred lines coming from different countries were selected to perform the study. The genetic variability consisted in two types of experiments: in vivo and in vitro cultures. The recombinant inbred lines were classified usi...

Recombinant inbred lines derived from an advanced intercross, in which multiple generations of mating have increased the density of recombination breakpoints, are powerful tools for mapping the loci underlying complex traits. We investigated the effects of intercross breeding designs on the utility of such lines for mapping. The simplest design, random pair mating with each pair contributing ex...

The generation of special crosses between different inbred lines such as recombinant inbred strains (RIS) and intermated recombinant inbred populations (IRIP) is being used to improve the power of QTL detection techniques, in particular fine mapping. These approaches acknowledge the fact that recombination of linked loci increases with every generation, caused by the accumulation of crossovers ...
