Compilation of crack characteristics of sweet cherry fruit from a segregating population of a cross of ‘Regina’ x ‘Garnet’.

Cracking was assessed in a laboratory based immersion assay (n = 3) using the cracking index [38, 39], the time to half maximum cracking (T50) or the percentage of fruit cracked at infinity (asymptote) using fruit from grafted trees. Cracking in the field was recorded in eight growing seasons following exposure to natural rain using the same genotypes as above but on their own roots. These data are taken from Quero-Garcia, Letourmy [33]. The number of replicates was 16 susceptible and 21 tolerant genotypes including the parent cultivars Regina and Garnet.
