Comparative Study of Early and Late Maturing Rapeseed and Mustard Genotypes for Yield-related Traits and Fatty Acid Profiles

Abstract

Rapeseed and mustard are the leading oilseed crops in Bangladesh. The demand for edible oil is growing irrespective of Bangladesh's low oilseed production. An intensified rapeseed and mustard cultivation can mitigate the ongoing oilseed crisis in Bangladesh. The purpose of this analysis was to define the difference between late maturing and early maturing rapeseed and mustard genotypes in terms of yield, yield contributing characteristics and fatty acid profile. Two early maturing and twenty late-maturing rapeseed and mustard lines were used in the experiment. Two late maturing lines M-215 and M-219 showed noteworthy results yielding 4.56 tons and 4.16 tons per ha, respectively. These late maturing genotypes achieved higher yield by producing bigger plants with a greater number of primary, secondary, and tertiary branches along with a higher number of siliqua per branch. Notably, the early maturing variety BARI Sarisha-14 recorded the highest number of seeds per siliqua. These two late-maturing lines also measured slightly lower oil content, higher oleic acid content, and a lower erucic acid profile.
