Variability in Garo Hill Cotton in Meghalaya

Abstract

Race cernuum of Gossypium arboreum has unique characters /ike highest boll weight among the diploid cultivated forms -and highest number of seeds per loculus among all species of Gossypium. Ginning out-turn is also higher than any cultivated species and has tolerance to bollworm.  101 collections of'cernuum cotton from Garo-Hills of Meghalaya were made and observationfll on number of bolls/plant, boll weight, number of seeds/three tbcu/i in a boll and bollworm incidence wt:re recorded in the
field. Ginning· out-turn, seed index and lint index were recorded in the laboratory. Large variability in respect lO various characters was re,corded.Collection A-60 was found to be the best donor inover-all evaluation forvarious characters followed by A-24 and D 46-2-1.
