[Genetic analysis of oat (Avena sativa L.) by joint scaling test]
Abstract:
Comparing the results of genetic analysis of oat varieties with the method of diallel analysis of F1 hybrids and with the joint scaling test the spheres of optimal application of both methods were determined. Quantitative estimation of genetic parameters forming the phenotypic averages in scaling test develops the necessary base for involvement of marker genes for qualitative characters in search of QTLs controlling the traits with continuous variation. The crosses being the most suitable for further investigation with the aim to identify and to allocate the main genes of quantitative traits are indicated.

Monohybrid Crosses
Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
