Breeding ‘Sweet Pepper Parental Line Nou-1’ with Genic Male Sterility

Abstract

‘Sweet Pepper Parental Line Nou-1’ was selected from a cross between a male sterile plant of ‘Tokyo Piman’ and ‘101(2·4)-11-1-4’ (a seed parent line of ‘Beruhomare’). The cross shows genic male sterility, resistance to phytophthora blight and ToMV. It is suggested that genic male sterility is controlled by a recessive gene, and the resistance to phytophthora blight is controlled by a few incompletely dominant genes. Since genic male sterility is able to improve in F₁ seed production systems, ‘Sweet Pepper Parental Line Nou-1’ is expected to be used as a seed parent for F₁ cultivers of sweet peppers.
