Study on the mendelian inheritance of immature fruit color in bell pepper (Capsicum annuum L.) under North–Western Hills of India
摘要
Breeding for fruit color is a new area of agricultural research that aims to improve antioxidant quality, which is in high demand these days, especially in the bell pepper and gaining commercial importance worldwide. In this study, fifteen cross combinations were studied for immature fruit color, involving three parental genotypes namely, Solan Bharpur (Dark Green), UHF CAP-101 (Sulfury White) and UHF CAP-102 (Dark Purple). The F2 population of the cross Solan Bharpur × UHF CAP-101 exhibited incomplete dominance, segregating in the ratio of 1:2:1 (Dark Green: Light Green: Sulfury White). The fruit color at the immature stage of the cross between Solan Bharpur × UHF CAP-102 segregated in the ratio of 12:3:1 (Dark Green, Dark Purple, and Purple mixed with Green) in the F2 generation showing presence of dominant epistasis. Cross between UHF CAP-101 × UHF CAP-102 demonstrated both dark purple and sulfury white fruit colors in F1 and further segregated in the ratio of 1 (Sulfury White): 2 (Intermediate): 1 (Dark Purple) in F2 generation. This cross showed mechanism of dominance. These results of the study add to the existing knowledge about the inheritance of bell pepper immature fruit color by providing new information.
