Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Different Methods for Detecting Heterotic Groups in Maize

journal of King Abdulaziz University - Meteorology, Environment and Arid Land Agriculture Sciences, 2017
Comparing between different methods for classifying 12 maize inbred lines to heterotic groups was achieved using general and specific combining ability effects; agronomic traits to the maize inbreds per se; and ISSR-markers. The results of line-tester design showed that Giza656 lines had the highest yield for the cross with Gemmiza 1021 tester (7.20 ...

Determination of Heterotic Groups in Nepalese Yellow Maize Populations

Nepal Journal of Science and Technology, 1970
Assigning germplasms into different heterotic groups is fundamental for exploitation of heterosis for hybrid development. An experiment was conducted in order to establish heterotic groups of some maize populations. Line x tester design was used for making crosses. Ten open pollinated varieties were used as lines and four as testers.

Exploring the landscape of heterotic strings on T d

Journal of High Energy Physics, 2020
Compactifications of the heterotic string on T d are the simplest, yet rich enough playgrounds to uncover swampland ideas: the U(1) d+16 left-moving gauge symmetry gets enhanced at special points in moduli space only to certain groups. We state criteria,

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Bordism for the 2-group symmetries of the heterotic and CHL strings

, 2023
In the presence of a nonzero B-field, the symmetries of the $\mathrm E_8\times \mathrm E_8$ heterotic string form a 2-group, or a categorified group, as do the symmetries of the CHL string. We express the bordism groups of the corresponding tangential structures as twisted string bordism groups, then compute them through dimension 11 modulo a few ...

Combining ability among provitamin A‐enriched maize inbred lines and heterosis of their hybrids for grain yield and agronomic traits

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Studying the combining ability of pro‐vitamin A enriched yellow maize inbred lines (Zea mays L.) provides valuable information on the breeding potential of these lines for developing high‐yielding and biofortified maize hybrids with desirable agronomic traits.

The progressive modernization of cassava breeding programs at International Institute of Tropical Agriculture and future prospects

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Modernizing cassava breeding programs (CBPs) is critical to increase genetic gain, close the yield gap, and ensure food availability, accessibility, and affordability to support livelihood transformation and economic development in sub‐Saharan Africa (SSA).

Tandem genomic selection with independent culling to improve sorghum hybrid adaptation to the eastern United States

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Objectively selecting genotypes using genomic predictions for multiple traits warrants more empirical research. This study investigated how deployment of genomic prediction within the Clemson sorghum [Sorghum bicolor (L.) Moench] breeding program would help to develop hybrids adapted to the eastern United States.

Heterosis and Heterotic Grouping among Tropical Maize Germplasm

, 2021
Maize (Zea mays L.) is the most important staple cereal cultivated in sub-Saharan Africa but its productivity is considerable low due to several factors. Development and deployment of maize hybrids have been reported as one of the crucial options in achieving sustainable maize production in sub-Saharan Africa.
