EFFECT OF WHEAT GENOTYPE ON YIELD AND PROXIMATE COMPOSITION

Abstract

An experiment was conducted to study the proximate composition of four released and two advanced line of wheat varieties (Triticum aestivum) which was popularly growing in Bangladesh namely BARI gom-22 (Sufi), BARI gom-23 (Bijoy), BARI gom-24 (Prodip), Sonora-64, WYCYT (E-13) and WYCYT (E-14). There was none a single variety performed best in all nutrient parameters. Among these released and advanced line of wheat varieties, highest grain weight was found in BARI gom-23 (Bijoy) (52.35g) and the lowest weight of thousand seeds was found in Sonora-64 (33.21g). BARI gom-24 performed the best among the varieties only in some nutrient parameters. In case of proximate analysis, the highest protein content was recorded from BARI gom-24 (10.04%) and the highest carbohydrate was recorded from WYCYT (E-14) (72.84%). Among the other wheat varieties, BARI gom-24 contained highest amount of fibre (13.89%). WYCYT (E-13) contained highest amount of fat (1.83%) and BARI gom-22 contained highest amount of ash (2.13%). On the other hand BARI gom-24 (prodip) contained the lowest amount of carbohydrate (67.62%) and WYCYT (E-14) contained the lowest amount of protein (9.10%). WYCYT (E-14) contained lowest amount of fibre (10.21%) and BARI gom-22 (Sufi) contained the lowest amount of fat (1.03%). Sonara-64, BAREI gom-22 (Sufi) and WYCYT (E-13) showed the best performance for the most of the minerals.
