- Abstract
American cotton [ Gossypium hirsutum (L.)] grown in India belongs to the race Latifolium. It is prone to bollworms [ Helicoverpa armigera (Hubner), Erias vitella (Fabricius), Pectinophora gossypiella (Saunders)] infestation which causes considerable crop loss. Two breeding lines ‘Bikaneri (BN)- arboreum (ARB)-16’ and ‘BN- tomentosum (TOM)-277’ are cytoplasmic diverse genetic stocks. They were developed by crossing experimental lines ‘Delta Branch Experiment Station (DES)-ARB16’ and ‘DES-TOM277’ (non-recurrent parents) with G. hirsutum‘BN’ (recurrent parent). Compared with BN these stocks possessed higher amount of gossypol, flavonol and phenol contents in leaves, stem and square. Plants were tolerant to bollworms and inherited comparable agronomic properties (yield, boll weight, plant height, number of monopods and sympods and fibre quality). Cotton breeders can use these lines for breeding cotton resistant to bollworm.
