Abstract

Phalsa genotypes were characterized on the basis of DUS guidelines at experimental orchard, RRS Bawal. The genotypes
were maintained under similar agronomic practices in randomized block design. The growth parameters were measured in
the month of May and fruiting parameters were recorded at the maturity of fruits or at the time of picking. The qualitative
data was observed by jury members by matching with the DUS characteristics. On overall basis the genotype was divided
into three groups, tall, dwarf and tall plants with globose shaped fruits. The dwarf genotype starts bearing earlier than tall
plants and tall plants with globose shaped fruits were late bearers. The yield of tall genotype was higher as compared to
dwarf. However, shelf life of dwarf plants (roundish fruit), tall plants (roundish shape) and tall plants with globose shaped
fruits was more as compared to fruits of tall plant. Fruits of tall genotypes were slightly infected with fruit fly in the last
picking; however other two genotypes (dwarf plants and tall plant with globose shaped fruits) were resistant to fruit fly.
None of the genotypes was infected with any disease. The fruit size and fruit weight of globose shaped fruits was more,
however the seed size was also more. It is concluded from the four years study that the tall genotype having globose
shaped fruits is a new and elite genotype with higher fruit weight, fruit yield and shelf life of fruits.
