Corolla

A whorl, or whorls, of petals that forms the inner envelope of a flower. The petals may be either free or joined, and they are often brightly coloured to attract pollinating insects. Corporate plant breeding

Plant breeding undertaken by large corporations, usually chemical manufacturers. Their motives are suspect, as they naturally have a preference for chemical pesticides rather than horizontal resistance. Consequently, they can be expected to produce new cultivar that have excellent yield, quality, and agronomic suitability, but that also have low levels of resistance. Corporate plant breeding is also involved in genetic engineering and the production of cultivars that have special properties, such as resistance to herbicides. Corylus avelana

The hazel nut, cobnut, or filbert. This species shows considerable diversity and some taxonomists have suggested additional specific names. Not much scope for amateur breeders
