AGRONOMIC PERFORMANCE OF LOW CHILLING AND NON-MELTING PEACH GERMPLASM IN SOUTHEAST OF SPAIN

Eight low chilling and non-melting peach cultivars bred in Brazil and ‘Romea’ (reference cultivar) were evaluated at Region of Murcia during two seasons.
Traits such as bud break and flowering time, chilling and heat requirements, productivity and fruit quality were assessed. ‘Precocinho’ and ‘Pepita’ were the earliest in flowering (2 and 3 weeks earlier than ‘Romea’) and ripening (14 and 10 days earlier than ‘Romea’) Heat requirements differed between cultivars with similar chilling requirements.
Lowest chilling requirements cultivars showed fruit drop before harvest, especially ‘Pepita’. ‘Granada’ showed the greatest fruit weight and ‘Precocinho’ the lowest.
All cultivars had high productivity, especially ‘Granada’. Most of the cultivars had round or round flat shape.
Low percentage of tips and split pit were observed excepting in ‘Romea’ (10-30% of stylar tips depending of the year). In general, total soluble solids content were high, ranging between 11 to 15°Brix.
