Study on resistance to papaya ringspot virus (PRSV) in intergeneric hybrid population of papaya CV washington (Carica papaya L.) and Vasconcellea cauliflora

Author(s): SU Chalak and SN Hasbanis
Abstract: An intergeneric hybridization programmee was conducted between papaya cultivar Washington (Carica papaya L) and Vasconcellea cauliflora. The objective was to incorporate the PRSV resistantce from V. cauliflora in to papaya CV Washington. From the cross six plant types were studied. Among these selections, present population study of promising papaya selection GKPS-2-7 (F7 generation) was conducted at ZARS, NARP, Pune during 2015-16. The performance of this promising selection population was studied in comparison with popular cultivars viz. Arka Prabhat and Red Lady. From this study it was observed that, at 7 months after planting genotype GKPS-2-7 recoded minimum ring spot infection (1.24 as Per cent Disease Index) However, cultivars Arka Prabhat and Red Lady recorded maximum papaya ring spot infection ( 54.00 and 100 as Per cent Disease Index respectively). This selection is to be explored for further development of a papaya ring spot resistant cultivar.
