GENETIC DIVERSITY OF FIELD MUSTARD (BRASSICA RAPA L.) AND THEIR SATURATED AND UNSATURATED FATTY ACIDS ASSOCIATION

The oilseed crop improvement for Brassica rapa L. (field mustard) is considered to be important in respect of yield production coupled with unsaturated fatty acids the existing cultivars. Hence, genetic diversity, and nutritional components 14 B. cultivars were evaluated based on their attributes acid profiles at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. These differed significantly grouped into five diversified clusters. highest intra-cluster distance was found cluster II (2.43), while inter-cluster between clusters V (20.41). In profile, maximum threshold acceptable level (<7%) saturated human consumption Sonali Sarisha BARI Sarisha-14. total monounsaturated viz., oleic, eicosenoic, erucic ranged from 62.74% Sarisha-15 69.51% Sarisha. oleic eicosenoic obtained local variety, Maghi (21.06%) Improved Tori (9.08%). essential linoleic linolenic (17.10%) (8.16%), respectively. However, cultivar Maghi, containing has lowest (35.53%). On other hand, Sarisha-14 contained (17.22%) (44.02%) acids. negative strong correlation also reinforced reverse relationship Similarly, both (-0.497) (-0.443) showed a acid. As whole, Sarisha-14, Sarisha-15, Sarisha, could selected as potential parents hybridization program breed recombinant lines higher oil content healthier
