Performance and Variation of White Maize Inbred Lines Developed from Different Sources for Yield and Drought Tolerance [PDF]
Fifty S1, S2 and S3 white maize lines were extracted and developed from five open different populations for searching of new maize inbreds that tolerate drought accompanied with distinct performance as heterotic groups.

Background Assessment and effective utilization of genetic diversity in breeding programs is crucial for sustainable genetic improvement and rapid adaptation to changing breeding objectives. During the past two decades, the commercialization of the early

Heterosis refers to a quantitative phenomenon in which F1 hybrid trait values exceed the mean of the parental values in a positive direction. Generally, it is dependent on a high degree of heterozygosity, which is maintained in hybrid breeding by ...

Selection of Sweetpotato Parental Genotypes Using Simple Sequence Repeat Markers
Knowledge of the genetic diversity and genetic relationship is important in crop improvement. The objective of this study was to determine the genetic diversity of 31 sweetpotato genotypes and furthermore to select distantly related individuals for ...

Duality symmetry group of two dimensional heterotic string theory [PDF]
The equations of motion of the massless sector of the two dimensional string theory, obtained by compactifying the heterotic string theory on an eight dimensional torus, is known to have an affine o(8,24) symmetry algebra generating an O(8,24) loop group.

Nongeometric heterotic strings and dual F-theory with enhanced gauge groups
Eight-dimensional nongeometric heterotic strings were constructed as duals of F-theory on Λ1,1 ⊕ E 8 ⊕ E 7 lattice polarized K3 surfaces by Malmendier and Morrison. We study the structure of the moduli space of this construction. There are special points

Compact, singular G 2-holonomy manifolds and M/heterotic/F-theory duality
We study the duality between M-theory on compact holonomy G 2-manifolds and the heterotic string on Calabi-Yau three-folds. The duality is studied for K3-fibered G 2-manifolds, called twisted connected sums, which lend themselves to an application of ...

Genomic models for prediction of additive and non-additive effects within and across different heterotic groups are lacking for breeding of hybrid crops. In this study, genomic prediction models accounting for incomplete inbreeding in parental lines from

Twisting toroidally compactified heterotic strings with enlarged symmetry groups
In toroidal compactification of string theory, enlarged symmetry groups arise at special radii of the compactified dimensions. Here an orbifold-like construction is considered in which the degrees of freedom describing the compact spatial dimensions are twisted by symmetries which exist only for special values of the radius. Constraints on the possible

Heterotic Patterns of Temperate and Tropical Maize by Ear Photometry
As the plant variety protection (PVP) of commercial inbred lines expire, public breeding programs gain a wealth of genetic materials that have undergone many years of intense selection; however, the value of these inbred lines is only fully realized when
