Hybrid vigour in cabbage (Brassica oleracea var. capitata) under mid hill conditions of central Himalaya.

Abstract: Eight inbred lines of cabbage, namely Sel-2, Sel-3, Sel-4, Sel-1, Sel-36 Sector, Sel-6, Sel-5 and Sel-7, were crossed in all possible combinations (excluding reciprocals), and the 28 F1s along with their parents were planted in September 2001 in Pithoragarh, Uttaranchal, India. Sel-1 x Sel-36 Sector was identified as the best among all combinations, having significant hybrid vigour (heterosis) for biological yield, head weight, net weight of head and head size index.
