Many commercial inbred lines are available in crops. A large amount of genetic variation is preserved among these lines. The genealogical history of the inbred lines is usually well documented. However, quantitative trait loci (QTL) responsible for the genetic variances among the lines are largely unexplored due to lack of statistical methods. In this study, we show that the pedigree informatio...

I prove two theorems: Let X ⊂ P be a hypersurface and let x ∈ X be a general point. If the set of lines having contact to order k with X at x is of dimension greater than expected, then the lines having contact to order k are actually contained in X. A variety X is said to be covered by lines if there exist a finite number of lines in X passing through a general point. Let X ⊂ P be a variety co...

The somatic regeneration of maize depends on its genotypes, so improving variety with modern biotechnology is severely restricted. Locating the quantitative trait loci (QTLs) associated important for breeding elite inbred lines that undergo genetic transformations. Here, by crossing high-regeneration line H99 and non-regeneration Fr993, an F2 population F2:3 F2:4 families were constructed. Imma...

The farmland of the world’s main corn-producing area is increasingly affected by salt stress. Therefore, breeding salt-tolerant cultivars necessary for long-term sustainability global corn production. Previous studies have shown that natural maize varieties display a large diversity tolerance, yet genetic variants underlying such remain poorly discovered and applied, especially those mediating ...

The application of unmanned aerial vehicle (UAV) remote sensing technology for high-throughput acquisition phenotypic values field plant height is great significance in monitoring wheat varieties (lines). Based on the UAV, mounted with high-resolution digital cameras, a low-altitude platform was built to obtain images Berkut/Worrakatta recombinant inbred lines (RIL) population (297 lines). opti...

the primary aim of plant breeding is to improve stability in yield and to obtain varieties with good quality. for this reason, a study of wheat varieties was conducted in 2010, 2011, and 2012 at the agricultural application and research center fields of the uludag university, agricultural faculty, in bursa/turkey. in the study, 22 advanced lines of bread wheat and gonen, pehlivan, and flamura c...
