Evaluation of Different Kharif Onion (Allium cepa L.) Genotypes in Chhattisgarh Plains

Present investigation was undertaken at Research and Instructional Farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during kharif season of 2010-2011 in a randomized block design with three replications. Evaluation of 23 genotypes of kharif onion revealed that the BKHO-1002 was found best for total bulb yield (39.34 t/ha), average bulb weight (195.63 g), polar and equatorial diameter of bulb (7.78 and 8.18 cm). Whereas, BKHO-1007 recorded highest total soluble solids (13.62%) maximum plant emergence per cent (66.33%) and maximum plant height (72.43 cm) and neck thickness (1.98 cm) recorded in BKHO-1004, number of leaves per plant found maximum (10.53) in BKHO-1005. Analysis of variance revealed that the mean sum of square for all the characters is significant. BKHO-1002 and BKHO-1003 with larger polar and equatorial diameter of bulb, bulb weight, marketable and total bulb yield and BKHO-1007 indicated that maximum TSS are advocated for commercial cultivation in kharif season.
