EFFECT OF PARENT PLANT GROWING TEMPERATURES ON THE PERFORMANCE OF WHEAT IN NEXT GROWING SEASON

Abstract

Seed of four wheat genotypes (BARI Gom-27, E-22, BARI Gom-30, BARI Gom26) obtained from normal and high parent plant growing temperature was grown at the research field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of November 2016 to April 2017 to evaluate their performance as next crop. The experiment was conducted following two factors Randomized Complete Block Design with three replications. Parent plant growing temperature and interaction of parent plant growing temperature and wheat genotypes did not influence the plant height at different days after sowing and at harvest but in most cases plant height was influenced significantly by wheat genotypes. Seed obtained from normal parent plant growing temperature produced greater number of tiller per plant at different days after sowing and BARI Gom-26 performed better in tiller production. High parent plant growing temperature accelerated anthesis and physiological maturity in the next wheat crop. Seed obtained from normal parent plant growing temperature performed better than seed obtained from high parent plant growing temperature in respect to yield and yield attributes. Among the seed of the wheat genotypes obtained from high parent plant temperature, seed of BARI Gom-26 performed better in next growing season.
