The study was conducted in the Post Graduate Laboratory of Vegetable Crops, Bidhan Chandra Krishi Viswavidyalaya employing Ten varieties of onion containing ninety seeds of each treatment in 3 replications of 30 each were taken for germination test following the between paper (BP) method (ISTA, 1985) under growth chamber. Ten normal seedlings were selected on the fourteenth days of germination test (i.e., final count day) and their root and shoot lengths were measured in centimetre. The mean seedling root and shoot length was calculated based on ten seedlings. Protein content was estimated from the seeds and the seedlings which grew appreciably within ten days in growth chamber after germination. Analysis of variance clearly suggested wide varietal difference for all the characters viz., protein content of dry seeds (%), protein content of 10 days seedlings % (fresh weight basis), protein content of the seedlings % (dry weight basis), seed germinability (%) and length of seedlings (cm). Mean of the different seed and seedling characters indicated recommended minimum seed germinability (above 60%) in all the variety excepting Nasik Red (56.8%). Very high seed germination is being recorded in two outstanding varieties for its very high seed production potential in this method and climatic condition of West Bengal viz., Agrifound Dark Red (93.4%) and Baswant 780 (97.0%) which indicated close correspondence between seed production ability and seed germinability. Seedling protein content on dry weight basis was lower than recorded in the seeds and it also varied widely from 6.60 % in Agrifound Dark Red to 11.05% in Baswant 780. However, seed germinability also was uncorrelated with both seed and seedling protein content.
