Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

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

open access: yesPlant 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.

Milk production and survival of spring-calving carryover cows in New Zealand dairy herds : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Animal Science at Massey University, Manawatu, New Zealand [PDF]

open access: yes, 2017
Non-pregnant cows are generally culled from dairy herds and replaced with two-year-old heifers. Alternatively, non-pregnant cows can be dried-off at the end of lactation, retained for one year (carried over), before being mated and returned to a milking ...

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

open access: yesPlant 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.

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

open access: yesElectronic 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.

Comparing Cold Tolerance of sorghum (S. bicolor) A1 and A2 Cytoplasm‐Based Hybrids

open access: yesPlant Breeding, EarlyView.
ABSTRACT Systematic exploitation of heterosis via breeding of F1 hybrids is a major contributor to genetic gain in many major crops, including sorghum (Sorghum bicolor L. Moench). Different cytoplasmic male sterility (CMS) systems have been identified for controlled F1 hybrid seed production in sorghum, with the so‐called A1 and A2 CMS systems being ...

Chromatographic separation and identification of some peptides in partial hydroylsates of gelatin [PDF]

open access: yes, 1953
Recently we have been engaged in a study of the chemical structure of collagen and gelatin with the object of determining the sequence of the amino acid residues in the polypeptide chains of these proteins.

Multi‐generation analysis of whether local or genetically mixed populations perform best in restoration plantings

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Proper selection of genetic material is critical for restoring populations, with local seed often selected to maximize local adaptation. But if local populations are small, inbred, or maladapted, then including genotypes from various populations may enhance population growth and long‐term adaptation.
