Genetic Gain Trend in Yield and Advanced Selection of Yayo Coffee (Coffea arabica L.) Land Race Collection

open access: yesAdvances in Agriculture, 2022
Coffea arabica L., the dominant cash crop in the world market, is native to rain forest of Ethiopia where it is believed to exist with high genetic diversity. Estimating genetic parameters are momentous in deciding breeding method to be followed for crop

Prior Mating Experience Modulates the Dispersal of Drosophila in Males More Than in Females [PDF]

open access: yes, 2011
Cues from both an animal’s internal physiological state and its local environment may influence its decision to disperse. However, identifying and quantifying the causative factors underlying the initiation of dispersal is difficult in uncontrolled ...

Homoeologous Chromosomes From Two Hordeum Species Can Recognize and Associate During Meiosis in Wheat in the Presence of the Ph1 Locus

open access: yesFrontiers in Plant Science, 2018
Understanding the system of a basic eukaryotic cellular mechanism like meiosis is of fundamental importance in plant biology. Moreover, it is also of great strategic interest in plant breeding since unzipping the mechanism of chromosome specificity ...

A Simplified Strategy for Introducing Genetic Variants into Drosophila Compound Autosome Stocks

open access: yesG3: Genes, Genomes, Genetics, 2016
Drosophila stocks bearing compound chromosomes, single molecules of DNA that carry the genomic complement of two chromosomes, are useful tools for studying meiosis and mitosis.

The Correlation of Cytological and Genetical Crossing-Over in Zea Mays. A Corroboration [PDF]

open access: yesProceedings of the National Academy of Sciences, 1935
In this article, McClintock and Creighton addressed critics who felt their 1931 paper did not have enough data by corroborating their earlier findings on crossing-over.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

open access: yes, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

New Applications of Radio Frequency Identification Stations for Monitoring Fish Passage through Headwater Road Crossings and Natural Reaches [PDF]

open access: yes, 2018
Within the Ouachita National Forest, roads and streams intersect each other thousands of times. Many of these road crossings alter stream hydrology and potentially limit longitudinal fish movement.

Optimization of a crossing system using mate selection

open access: yesGenetics Selection Evolution, 2006
A simple model based on one single identified quantitative trait locus (QTL) in a two-way crossing system was used to demonstrate the power of mate selection algorithms as a natural means of opportunistic line development for optimization of ...

Genetic Regulation of Meiotic Cross-Overs between Related Genomes inBrassica napusHaploids and Hybrids   [PDF]

open access: yesThe Plant Cell, 2009
AbstractAlthough the genetic regulation of recombination in allopolyploid species plays a pivotal role in evolution and plant breeding, it has received little recent attention, except in wheat (Triticum aestivum). PrBn is the main locus that determines the number of nonhomologous associations during meiosis of microspore cultured Brassica napus ...
