Harnessing exotic germplasm for red clover improvement: Tracking genomic introgression and deploying genomic selection

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Red clover (Trifolium pratense L.) is a globally important temperate forage legume. Its symbiosis with soil‐borne rhizobia enables nitrogen fixation, and its ability to produce quality forage under diverse soil conditions enhances pasture productivity, particularly during water deficits.

Partial unidirectional translocation from 5AL to 7BS leads to dense spike in an EMS-induced wheat mutant

BMC Genomics
Background As the inflorescence of wheat, spike architecture largely determines grain productivity. Dissecting the genetic basis for the spike morphology of wheat can contribute to the designation of ideal spike morphology to improve grain production ...

Heterosis analysis for grain yield traits in Maize (Zea mays L.)

Electronic Journal of Plant Breeding, 2018
In the present study 6 inbreds were used as parents to make crosses in all possible cross combination in full diallel fashion to obtain total 30 possible F1 hybrids. These 30 F1’s were subjected to heterosis analysis for midparental, heterobeltiosis and

'Heterosis' in Drosophila [PDF]

Evolution, 1963
In the course of some experiments with Drosophila melanogaster on the adaptive value of several dominant mutants in competition with their wild-type alleles, an anomalous situation arose with respect to Lobe-2. Further investigation of these results produced an explanation which raises some interesting questions about reports of heterosis in Drosophila.

Re‐sequencing 142 rice genomes reveals the fine‐scale population structure and phylogenetic affinities of landraces of Kashmir Valley: Evidence from domestication and adaptive signatures

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract The emergence of rice (Oryza sativa) as a cultivated crop has represented a landmark in the history of agriculture in Kashmir Valley. Unlike winter cereals, such as wheat and barley, which exhibit clear West‐Asian origins, rice attained a different domestication trajectory linked to East‐Asian Neolithic cultures.

Estimation of heterosis in pearl millet [Pennisetum glaucum (L.)] for yield and quality traits

Electronic Journal of Plant Breeding, 2016
Five CMS lines were crossed with nine testers in a line x tester design to study the extent of heterosis in pearl millet for yield and quality traits. Heterosis was observed in both directions for most of the characters.

The richness, frequency and relatedness components of mate diversity and mate portfolios

New Phytologist, Volume 251, Issue 6, Page 3703-3713, September 2026.
The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

Cross‐ploidy hybridisation in Alpine woodrushes is associated with ecological additivity and scale‐dependent niche divergence

New Phytologist, Volume 251, Issue 6, Page 3669-3686, September 2026.
Genetic differentiation among the study species. Summary Hybridisation and whole‐genome duplication (WGD) are widespread in plants, yet their ecological consequences remain challenging to predict. In allopolyploids, where both processes coincide, ecological divergence is typically evaluated against a null hypothesis of ecological additivity.

HETEROSIS BASED ON MALE STERILITY IN COTTON

Heterosis is a method of increasing productivity and is used in many crops. In cotton, heterosis is mainly related to yield and fiber length. Two male-sterile cotton lines ms 273 and ms 274 were included in crosses with five modern varieties: Chirpan-539,
