Which Seed Properties Determine the Preferences of Carabid Beetle Seed Predators?

open access: yesInsects, 2020
Ground beetles are important invertebrate seed predators in temperate agro-ecosystems. However, there is a lack of information regarding which seed properties are important to carabids when they select seeds for consumption.

Modified Soft Brood Crossover in Genetic Programming [PDF]

open access: yesarXiv, 2013
Premature convergence is one of the important issues while using Genetic Programming for data modeling. It can be avoided by improving population diversity. Intelligent genetic operators can help to improve the population diversity. Crossover is an important operator in Genetic Programming. So, we have analyzed number of intelligent crossover operators

Hurdles and clarifications for the cultivation of saffron in Jammu and Kashmir

open access: yesJournal of Agriculture and Food Research, 2022
Since saffron is a triploid crop, it does not generate seed when selfed or crossed and is passed down through the generations by daughter corms produced from the mother corms.

Assessment of genetic diversity in crop plants - an overview

open access: yes, 2017
Crop plant evolution either natural or human-directed, is primarily based on existing genetic diversity in the population. Diversity can be described as the degree of differentiation between or within species. Existing intraand inter-specific differences

The Effect of Strong Purifying Selection on Genetic Diversity

open access: yesGenetics, 2017
Negative selection is a ubiquitous evolutionary force, but its effects on diversity in large samples are poorly understood. Cvijović, Good, and Desai obtain simple analytical expressions for the whole population site frequency spectrum....

Genetic variability and genetic diversity in sunflower

open access: yesElectronic Journal of Plant Breeding, 2016
One hundred and seventy four accessions of sunflower were evaluated in a randomized block design with two replications during Kharif 2010-11 at Regional Agricultural Research Station, Nandyal, Andhra Pradesh to investigate the extent of genetic variability and genetic diversity.
