TABLE 6.

Incidence of Tipburn (TB) among recombinant inbred lines (RILs) in the 2016 experiment at T1 (25°C day/20°C night) (16T1) and the 2017 experiment at T3 (35°C day/30°C night) (T3) and association with marker solcap_snp_sl_53335 (located in position 58 cM of chromosome 7).

Genotype	Number of RILs	Experiment
		16T1		17T3
		RILs with TB	RILs No TB	RILs with TB	RILs No TB
EE	58	28	30	42	16
PP	78	57	21	44	34
	p	0.0002		0.0011

Genotype indicates homozygous “MoneyMarker” (MM) and homozygous TO-937 (PP) for the marker, followed by the total number of RILs with the genotypes and number of RILs within each genotypic class displaying or not displaying TB. In the lower part of the table, the significance of the χ² test for marker/TB association is shown.
