MAIN TRENDS OF MAIZE BREEDING IN ARRIGC NAMED AFTER I.G. KALINENKO

Зерновое хозяйство России, 2018
The main trends of the breeding of new corn hybrids in ARRIGC are the breeding of the hybrids with tolerance to drought, high water yielding capacity of the grain during ripening, high contents of starch in grain, breeding for ensilage and green forage ...

Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

Advanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

BREEDING OF SIMPLE MODIFIED MAIZE HYBRIDS ON SISTER CROSSINGS

Зерновое хозяйство России, 2018
According to the amount of self-pollinated lines we distinguish such main types of maize hybrids as simple interline, three-line and double interline ones. Simple interline hybrids are considered to be the most productive and stable.

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

Income sharing for common pool resources with uncertain productivity

American Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

Assessment of combining ability for grain yield of self-pollinated S5 maize (Zea mays L.) families of mixed germplasm

Plant Varieties Studying and Protection, 2016
Purpose. Assessment and selection of self-pollinated S5 maize (Zea mays L.) families with high combining ability and wide adaptive capacity obtained on the basis of specially produced hybrids by crossing elite lines of various genetic plasms with the ...

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 ...

Genetic analysis of flower color differences between a hummingbird-pollinated and a self-pollinated monkeyflower (Mimulus) species

, 2020
Flower color plays an important role in pollinator discrimination and speciation. Understanding the genetic contributions to flower color differences between two closely related species, Mimulus cardinalis and Mimulus parishii, can improve understanding ...
