Marker assisted rice breeding for resistance to biotic and abiotic stressors

BIO Web of Conferences, 2020
Due to the fact that blast (causative agent – Pyricularia oryzae Cav.) is considered to be one of the harmful diseases of rice around the world, weeds compete with the crop for light, mineral nutrition and space, the accelerated development of resistant ...

Cumulative individual seed production in the polycarpic Caesalpinia gilliesii (Fabaceae): effects of temporal variability in floral display, plant density and pollination [PDF]

, 2016
In polycarpic species, floral display size and density of conspecific neighbours are time variable as well as their effects on pollination and fecundity.

Wheat-barley hybridization – the last forty years [PDF]

, 2013
Several useful alien gene transfers have been reported from related species into wheat (Triticum aestivum), but very few publications have dealt with the development of wheat/barley (Hordeum vulgare) introgression lines. An overview is given here of

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Evaluation of self-pollinated maize lines of BSSS germplasm by breeding traits in the Northern Steppe of Ukraine

The Scientific Journal Grain Crops, 2023
Topicality. BSSS germplasm is widely used in most breeding programs of leading companies, but is characterised by insufficient variety of precocious lines. The relevance of the work is to determine the main breeding traits of self-pollinated maize lines of the heterotic BSSS group adapted to the conditions of the Northern Steppe of Ukraine. Purpose.

Manifold limits on seed production by individual flowering plants

American Journal of Botany, EarlyView.
Abstract Premise Historically, angiosperm seed production has been considered to be either pollen or resource limited. However, seed production involves more than pollen and seed resources and typically involves multiple ovules in multiple flowers. Therefore, various constraints may act simultaneously. Methods Proportional components of seed production
