The relationship may reflect greater fitness and is consistent with the heterotic effect reported in our lines (Yang and Siegel, 1998).
So, use of local CMS line would be helpful to alleviate this problem and to develop adaptable, heterotic hybrids.
because these traits are controlled largely by heterotic genetic effects
Finally, the hybrid can also be heterotic, that is, depart widely from the range of variation of both parental species in a given character.
Among the topics are elusive worldsheet instantons in heterotic string compactifications, the Witten equation and the geometry of the Landau-Ginzburg model, algebraic topological string theory, the fibrancy of symplectic homology in cotangent bundles, and the theory of higher rank stable pairs and virtual localization.
Considering the above idea in mind the present investigation was undertaken with the objectives (i) to determine the magnitude of heterosis as well as hybrid performance for some desirable yield contributing characters and (ii) to identify high heterotic parental combination in order to develop hybrid variety.
The same recommendations are being proposed for switchgrass in order to produce significant heterotic increases in biomass yield in managed cropping systems (Zalapa et al.
The objective for which the genetic diversity is to be worked out is, genetically diverse parents are likely to produce high heterotic [F.
Undaunted, theoretical physicists explore possible links between the field of inquiry and the fundamental theory, from the perspectives of string inflation from branes and moduli, cosmic superstrings, the cosmic microwave background as a possible probe of string theory, string gas cosmology, gauge-gravity duality, and heterotic M-theory and cosmology.
