Inheritance nature for the trait of resistance to neck rot in hybrid combinations of common onion under the conditions of Nosivka Variety Texting Station
The article highlights the results of studying hybrid combinations of common onion to the Botrytis allii Munn pathogen. It is found out that as for the combinations being studied the resistance to pathogen was inherited as dominant, intermediate or recessive trait. Better resistance to neck rot was...
