Varietal screening in ginger

Abstract

Twcntyfive ginger types were screened at the College of Horticulture, Vellanikkara during 1977-78 for the yield and quality attributes such asdrying percentage, oleoresin, oil and crude fibre contents. There was highly significant differences in yield, drying percentage, oleoresin, oil and crude fibre contents among the types studied. Maximum yield was recorded in the type 'Nadia' closely followed by 'Bajpai', 'Maran' and 'Narasapattom'. The maximum oleoresin percentagewas in the type 'Rio-de-Janeiro' and the highest percentage of oil recovery in 'Karakal'. But the yield per hectare of oleoresin and oil was maximum in the type'Maran' Crude fibre content was minimum in 'China' and the maximum in 'Kuruppampady"' The type Thodupuzha' recorded the maximum drying percentage of 25'20 and minimum in Karakal (15.20%). The types 'Nadia', 'Bajpsi' and 'Maran' were found to be relatively superior in performance in view of the higher yield of dry ginger, oleoresin and oil contents.
