When did cross breeding start?

1860sIn the 1860s, about the same time as Darwin, Gregor Mendel discovered he could cross breed different strains of pea plants and predict the traits of the offspring. He proposed that there was a genetic basis for inherited traits and demonstrated that he could control them.

What is pure line?

Medical Definition of pure line : a homogeneous line of descent: as. a : a group of closely related individuals of identical genetic constitution (as the offspring of a homozygous self-fertilized parent) : a line of descent theoretically realizable from the inbreeding of completely homozygous and comparable parents.

What are the common methods of plant selection?

The breeding methods that have proved successful with self-pollinated species are: (1) mass selection; (2) pure-line selection; (3) hybridization, with the segregating generations handled by the pedigree method, the bulk method, or by the backcross method; and (4) development of hybrid varieties.

What is mass selection?

In mass selection, seeds are collected from (usually a few dozen to a few hundred) desirable appearing individuals in a population, and the next generation is sown from the stock of mixed seed. This procedure, sometimes referred to as phenotypic selection, is based…

What is pure line selection?

Pure-line selection involves selecting and breeding progeny from superior organisms for a number of generations until a pure line of organisms with only the desired characteristics has been established.
