NEW APPLE AND PEAR SELECTIONS FROM HYBRID MATERIAL OF “IEDZENI” IN LATVIA

The apple and pear hybrid material bred by R. Abolins, A. Maizitis and R. Dumbravs is currently under evaluation in the Pure Horticultural Research Station (Latvia). Twelve accessions of conventional type apples, one compact columnar apple, one compact columnar and scab resistant apple and two pears have been selected as promising for cultivar registration.
The autumn hybrid AMD-19-54-15 (tentative name ‘Balva’) has a subacid taste, ‘Lobo’-like flavour and an excellent intensive red skin colour.
The late winter hybrid AMD-19-5-6 (tentative name ‘Daina’) is similar in flavour and colouring to ‘Lawfam’. It has a high level of disease resistance and marketable fruit size.
Winter hybrids AMD-12-15-6, AMD-19-14-23 and AMD-20-40-14 have excellent flavour, high yield capacity and marketable fruit appearance.
The late autumn hybrid AMD-20-33-23 (interim name ‘Saiva’) has an unusual fruit shape and an orange red skin colour.
The early winter hybrid AMD-55-29-21 (‘Yocco’) is characterised by an oblong fruit shape, a dark yellow skin and a high yield.
The winter hybrid AMD-49-11-6 (interim name ‘Atmodas masa’) has a unique refreshing acid taste.
The winter hybrid AMD-31-10-15 has a nice aroma and a taste similar to fruit candy.
The autumn hybrid AMD-35-16-37 (interim name ‘Jauna Melba’) is more attractive and tasty than ‘Melba’, with a similar aroma, but better scab resistance.
In addition two hybrids were selected for further breeding.
A natural semi dwarf apple AMD-55-24-15 has very juicy fruits and a good cropping capacity.
AMD-56-20-2 was selected for its precocity, good cropping, high level of disease resistance, optimal acidity and intensive red skin colour.
The compact columnar hybrid ‘Duets’ (D-12-90-2) and compact columnar scab resistant hybrid ‘Inese’ (D-4-90-3) are promising for ornamental purposes.
Both of them have fruits with the dessert grade of flavour.
Two pear selections, – late winter hybrid AMD-55-78-2 (‘Latgale’) and summer hybrid AMD-41-22-15 seem to be appropriate for the commercial orchards in the Baltic region.
