Abstract
‘Merbeingold 2336’ is a new Australian variety of mandarin. It was selected from the progeny obtained following a controlled pollination of ‘Imperial’ mandarinבEllendale’ tangor in 1984. It was selected because it is pollen sterile, strongly parthenocarpic and yields seedless fruits, which are sweet, juicy and easy-to-peel. Fruit maturity is early-to-mid season in the Murray Valley of Australia. Internally, the flesh of ‘Merbeingold 2336’ is attractive, orange in colour and tender with soft segment walls.
