This contribution shows the natural variation in flowering, harvest date and fruit quality traits. X Lapins Harvesting date: Harvesting date records: Estimate ripening date each two-three days. Quality assessments: C210-7 Standard quality assessments: good, rots, cracks, soluble solids, acidity, colour, fruit size, firmness, weight. X Aims: Colney Characterise phenotypical variation in the progeny to enable QTL analysis. Identify individuals with extreme phenotypes with a potential to extend harvest season due to delayed ripening/maturity. Results: The harvest period was between 16th of July and 21th of August. Half of the population had white flesh while the other half had black flesh. The average weight of the fruits were between 6-10 grams. There were only three hybrids with an average weight higher than ten. The 80% of the progeny had sugar content between 19-25 ºbrix and a 60% of the hybrids firmness was among 350-450 (g/mm). Period: 16th of July and 21st of August Average weight: 6-10 gr 80%  19-25 ºbrix 60%  350-450 g/mm2 50% white flesh/50 black flesh ! " # $%&'( )'* +$&,- . ' 3,&# 4%. . ' ' !" &#" &! " %#" %!
