Seems traditional breeding got there first - there is a vast selection at seeds-by-size.

The latter figure refers to varieties whose growth rate has already been improved by 2:1 as a result of traditional selective breeding.

Until recently, supercows have been developed through selective breeding - either traditional breeding or, since the 1960s, artificial insemination.

Simply put, traditional breeding takes plants with favorable characteristics and breeds them.

In traditional breeding, researchers fertilize one strain of a crop, like corn, with pollen from another.

Genetic engineering has many advantages over traditional breeding: it is faster, more precise and can introduce genes tailored to confer beneficial properties.

Others will be created through traditional breeding and food production.

This modification of gene material is not possible with traditional selective breeding.

Further deepening the blue colour would therefore require further modifications, by traditional breeding or further genetic engineering, to make the rose less acidic.

Genetic engineering is different from traditional breeding, where the organism's genes are manipulated indirectly.
