Pune Selection-1 (PS-1) (IC0611690; INGR15030), a Papaya (Carica papaya L.) Germplasm with Field Tolerance to Papaya Ringspot Virus and Yellow Pulp Colour

摘要

Pune Selection-1 (PS-1) is a near homozygous, yellow fleshed, dioecious papaya (Carica papaya L.) line. The line is consistently showing field tolerance to Papaya ringspot virus strain papaya (PRSV-P) with good yield (ICAR Report, 2012; AICRP Annual Report, 2013; Datar etal.,2Q3> and Sharma e/a/., 2011). The parental material was a segregating land race of papaya named Madhubala. PS-1 was selected from the segregating population in 2009. Since then, it is developed into a line by sib-mating and selection at IARI, Regional Station, Pune.
