Abstract:
Plant height, one of the most important factors for plant architectures, is closely related with some important traits such as plant density, lodging resistance and yields.. In the present study, 201 QTLs related to plant height of soybean from database and references were analyzed. The results revealed that 15 consensus QTLs located on chromosomes 6, 7, 11, 13, and 18 were identified after physical integrations and Meta analysis using the software BioMercator 2.1. Moreover, "Overview" method was used to optimize these QTLs based on statistic analysis. Some of the valid QTL regions were narrowed down to the 0.1 cM and mapped on certain chromosomes. Furthermore, the functions of all genes located in these confidence regions were predicted and 17 candidate genes that might be related to plant height were identified. These results would lay a foundation for fine mapping of QTLs related to plant height and marker-assisted breeding in soybean.

Chi-square Analysis
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
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...
