Genotypic Variation and Association Mapping for Plant Stature and Anthesis‐Silking Interval in Set of Temperate‐Adapted Maize Lines Developed by DH and SSD Methods

Plant Breeding, EarlyView.
ABSTRACT BS39 is a broad‐based population of tropical maize adapted to temperate environments that can provide useful and unique alleles to US Corn Belt breeding programmes. Doubled‐haploid (DH) has been used as an efficient alternative method to speed up the development of maize lines. Our objectives were to compare genetic parameters for plant height

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Floral morphometric analysis of Prosopis affinis Spreng. (Fabaceae) suggests flexibility of the reproductive system in isolated populations within the Brazilian Pampa

Annals of Forest Research, 2018
Morphological characteristics of inflorescences and flowers of Prosopis affinis growing in the Pampa biome were measured aiming to indirectly infer the species reproductive system.

In Vivo Propagation of Root Explants of the Dandelion Species Taraxacum kok‐saghyz, Taraxacum officinale and Their Interspecific Hybrids

Plant Breeding, EarlyView.
ABSTRACT The dandelion species Taraxacum kok‐saghyz is a promising new crop for natural rubber production and is currently in the early stages of the breeding process. To support these efforts, the multiplication and conservation of defined genotypes are crucial.

A Vertical Stacking Approach to Rapid Generation Cycling for Indoor Growth of Tall Annual Crops—The Case of Vicia faba L.

Plant Breeding, EarlyView.
ABSTRACT Accelerating breeding cycles through rapid generation turnover is a demonstrated strategy to improve the rate of genetic gain in a range of staple crops. This study presents a vertically stacked accelerated single‐seed descent (aSSD) protocol for faba bean (Vicia faba L.), aimed at rapid generation cycling while ensuring robust plant ...

Aggregate enantiostyly: Floral visitor interactions with a previously unreported form of floral display

Journal of Pollination Ecology, 2018
Floral herkogamy, or the spatial separation of reproductive structures, plays an important role in the evolution of plant mating systems. One form of herkogamy is enantiostyly, or the alternate presentation of stigmas to the left and right of the floral ...

Hemp seed counting and morphometric analysis method comparison

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract The USDA ARS Hemp Germplasm Laboratory recently acquired over 800 hemp accessions (Cannabis sativa L.). Variation in hemp seed size characteristics is needed to develop quantitative standards to support the transition of hemp grain into a commodity.

AFLP estimation of the outcrossing rate of Spondias tuberosa (Anacardiaceae), an endemic species to the Brazilian semiarid region Una estimación AFLP de la tasa de fecundación cruzada de Spondias tuberosa (Anacardiaceae), una especie endémica de la región semiárida de Brasil

Revista de Biología Tropical, 2013
The umbu tree (Spondias tuberosa) is one of the most important endemic species to the Brazilian tropical semiarid region. The umbu tree has edible fruits with a peculiar flavor that are consumed in natura or in a semi-industrialized form, such as jams ...

Mating system in a neotropical tree species, Senna multijuga (Fabaceae)

Genetics and Molecular Biology, 2004
Senna multijuga is a pioneer tropical tree species that occurs mainly in the Brazilian Atlantic forest. We investigated the mating system of two populations of S. multijuga, one located in a reserve area (RD1) and the other (RD2) about 15 km away.
