A cultivated blocky fruit type pepper plant, bearing extreme dark green color fruit at immature harvestable stage, said plant comprising two QTLs directing or controlling expression of said extreme dark green color in the pepper fruit of the pepper plant; wherein said QTLs are obtainable from Capsicum annuum 8728C, seed of which has been deposited under Deposit Number NCIMB 41858 on July 29th, 2011; wherein the first QTL, QTL1, is genetically linked to markers loci SP436 and SP626, wherein said marker locus SP436 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 1 and reverse primer of SEQ ID NO: 2 and probe SEQ ID NO 9, and said marker locus SP626 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 3 and reverse primer of SEQ ID NO: 4 and probe SEQ ID NO 10; wherein the second QTL, QTL2, is linked to markers loci SP693 and SP694; wherein said marker locus SP693 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 5 and reverse primer of SEQ ID NO: 6 and probe SEQ ID NO 11, and said marker locus SP694 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 7 and reverse primer of SEQ ID NO: 8 and probe SEQ ID NO 12; and wherein the extreme "dark green color" is associated with the following physicochemical characteristics of the pepper fruits at immature harvestable stage: - a content in Chlorophyll B greater than 6, particularly greater than 7, more particularly greater than 8 and even more particularly greater than 9 μg/g of fresh weight, - a content in Chlorophyll A greater than 20, particularly greater than 25, more particularly greater than 30 μg/g of fresh weight, - a content in lutein greater than 5, particularly greater than 6, more particularly greater than about 7 μg/g of fresh weight, a content in violaxanthin greater than 2, particularly greater than 2,5, more particularly greater than 3, even more particularly greater than 3,5 μg/g of fresh weight. wherein said QTLs are obtainable from Capsicum annuum 8728C, seed of which has been deposited under Deposit Number NCIMB 41858 on July 29th, 2011; wherein the first QTL, QTL1, is genetically linked to markers loci SP436 and SP626, wherein said marker locus SP436 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 1 and reverse primer of SEQ ID NO: 2 and probe SEQ ID NO 9, and said marker locus SP626 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 3 and reverse primer of SEQ ID NO: 4 and probe SEQ ID NO 10; wherein the second QTL, QTL2, is linked to markers loci SP693 and SP694; wherein said marker locus SP693 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 5 and reverse primer of SEQ ID NO: 6 and probe SEQ ID NO 11, and said marker locus SP694 can be identified in a PCR by amplification of a DNA fragment with the pair of oligonucleotide primers: forward primer of SEQ ID NO: 7 and reverse primer of SEQ ID NO: 8 and probe SEQ ID NO 12; and wherein the extreme "dark green color" is associated with the following physicochemical characteristics of the pepper fruits at immature harvestable stage: - a content in Chlorophyll B greater than 6, particularly greater than 7, more particularly greater than 8 and even more particularly greater than 9 μg/g of fresh weight, - a content in Chlorophyll A greater than 20, particularly greater than 25, more particularly greater than 30 μg/g of fresh weight, - a content in lutein greater than 5, particularly greater than 6, more particularly greater than about 7 μg/g of fresh weight, a content in violaxanthin greater than 2, particularly greater than 2,5, more particularly greater than 3, even more particularly greater than 3,5 μg/g of fresh weight. - a content in Chlorophyll B greater than 6, particularly greater than 7, more particularly greater than 8 and even more particularly greater than 9 μg/g of fresh weight, - a content in Chlorophyll A greater than 20, particularly greater than 25, more particularly greater than 30 μg/g of fresh weight, - a content in lutein greater than 5, particularly greater than 6, more particularly greater than about 7 μg/g of fresh weight, a content in violaxanthin greater than 2, particularly greater than 2,5, more particularly greater than 3, even more particularly greater than 3,5 μg/g of fresh weight.
