The present investigations were undertaken to evaluate the F2 intergeneric population of Carica papaya
(var. Pusa Nanha, CP 50 and CO 7) and Vasconcellea cauliflora for PRSV resistance. Investigations were
also made to estimate the mean performance, genetic parameters governing different traits and reaction
to the PRSV in the F2 population. Among the crosses, Pusa Nanha
×
V. cauliflora recorded superior mean
performance for fruit yield, number of fruits per tree and fruit biochemical parameters than other two
crosses in F2 generation. Mean performance for papain recovery per fruit and the enzyme activity were
high in CP 50
×
V. cauliflora. Fruit quality parameters were high in CO 7
×
V. cauliflora. Desirable mean performance
for days taken for disease after inoculation and disease intensity score were recorded by Pusa
Nanha
×
V. cauliflora. Among the various characters studied, higher GCV, PCV, heritability and genetic
advance as percent of mean were registered by the cross Pusa Nanha
×
V. cauliflora for all the morphological
characters and fruit yield parameters. From the F2 population 24 plus trees were selected for further
evaluation based on their performance viz., morphological, yield, quality and biochemical characters and
reaction to PRSV.
