Genetic Analysis of Seed Set in Wheat (Triticum aestivum L.) Hybrids Generated With Cytoplasmic Male Sterility Versus Chemical Hybridization Agents

Plant Breeding, EarlyView.
ABSTRACT The main challenge in hybrid wheat breeding is the low efficiency of hybrid seed production due to wheat's self‐pollinating nature. Efforts to improve cross‐pollination have mainly focused on enhancing pollen donor performance or increasing seed set in hybrids generated using chemical hybridization agents (CHA). Starting with 100 diverse wheat

MITOCHONDRIAL HETEROSIS IN MAIZE [PDF]

Genetics, 1968
MANY hybrids between genetic pure lines in maize exhibit heterosis. The search for the genetic basis of heterosis has been carried on for many years and by many workers. Despite these efforts, an adequate, specific biochemical explanation of heterosis has not been presented.

Fruit Quality and Fusarium Wilt Race 2 Resistance in Cucumis melo Breeding Lines and Their F1 Hybrids

Plant Breeding, EarlyView.
ABSTRACT Cucumis melo, a sweet‐tasting fruit from the Cucurbitaceae family, is popular in global markets. While some varieties of C. melo are used for pickling or salads, melons such as cantaloupes and honeydews are consumed as a dessert. Desirable appearance, shelf life and palatability are crucial in determining a variety's success.

Genome-Wide Transcriptional Analysis of Yield and Heterosis-Associated Genes in Maize (Zea mays L.)

Journal of Integrative Agriculture, 2012
: Heterosis has contributed greatly to yield in maize, but the nature of its contribution is not completely clear. In this study, two strategies using whole-genome oligonucleotide microarrays were employed to identify differentially expressed genes (DEGs)

Genetic Diversity and Population Structure of Sweetpotato Accessions (Ipomoea batatas [L.] Lam.) Revealed by Single Nucleotide Polymorphism Markers

Plant Breeding, EarlyView.
ABSTRACT Use of molecular markers has improved the analysis of genetic variation by eliminating environmental influences on genotype performance. The objective of this study was to assess the genetic diversity (GD) and population structure of 327 sweetpotato genotypes sourced from the major sweetpotato‐growing regions of Zimbabwe and from the ...

The Epigenetic Regulation of Agronomic Traits and Environmental Adaptability in Brassicas

Plant, Cell &Environment, EarlyView.
ABSTRACT As essential sources of vegetables, oilseeds, and forage, Brassica crops exhibit complex epigenetic regulation mechanisms involving histone modifications, DNA modifications, RNA modifications, noncoding RNAs, and chromatin remodelling. The agronomic traits and environmental adaptability of crops are regulated by both genetic and epigenetic ...

Map-based cloning and characterization reveal that an R2R3 MYB gene confers red glume in wheat

Crop Journal
Pigment accumulation is an important trait related to wheat domestication, but there remains a limited understanding of its molecular mechanism. The genetic control of the red glume trait by a dominant allele, Rg-B1, on 1BS was reported in the last ...

Development of SRAP Markers Linked to a Gene for Stem Nematode Resistance in Sweetpotato, Ipomoea batatas (L.) Lam.

Journal of Integrative Agriculture, 2013
Sequence-related amplification polymorphism (SRAP) markers closely linked to stem nematode resistance gene were developed in sweetpotato, Ipomoea batatas (L.) Lam. Using bulked segregant analysis (BSA), 200 SRAP primer combinations were screened with the
