Contract research project on adaptation of the land races to environmental stress and selection for better yield in sesame

Abstract

A research program was undertaken during Kharif 1999-2000 at three locations named Agricultural Research Station, BARI, Shyampur, farmer's field in village of Shyampur, Rajshahi and FSR (Farming Systems Research) site of Chabbishnagar Barind area to identify and analyze the adaptation of the land races collected from the sesame growing districts of Bangladesh and to select appropriate genotypes for local agro-ecosystems and cropping patterns with drought and water logging stress. Farmer's field and Barind area were considered as drought stress and research station was considered as water logging stress where six irrigation of 5 cm depth for 2 hrs was maintained at per plant, vegetative, flowering, capsule formation, capsule development and seed formation stages. Sixty four genotypes including one standard check T6 of sesame were used in the study and found that 22 genotypes gave better response in relation to growth , yield and yield contributing characters over check. These 22 genotypes gave 0.5%-52% increased yield over check and only P-129, P-141, P-150, P-133, P-139 and P-39 genotypes gave 52%, 45%, 34%, 29%, 27%, and 25% increased yield over check respectively.
