Incorporation of superior nutritional quality traits in Indian B. juncea
Abstract
The presence of high erucic acid in the seed oil and high gluconsinolate in the oil free meal limit the global utilization of Indian rapeseed mustard. In order to reduce the levels of erucic acid and glucosinolate in Indian mustard, B. juncea var. Varona was crossed with low erucic acid B. juncea strains Zem-1 and TERI (OE)M21, and the low glucosinolate line BJ-1058 for transfer of low erucic/low glucosinolate characteristics. Simultaneously, a unique three way cross; B. juncea (var. Varuna X Zem-1) X BJ-1058 was made for transfer of double low characteristics. The fatty acids and glucosinolates were analyzed and monitored through improved methods of GC and HPLC respectively. The progenies of selected plants were advanced through pedigree method and recurrent selections. The paper reports the transfer of low erucic acid (0–1.5%), low glucosinolate (9–25μm/g oil free meal) and double low (0% erucic acid and 10–27 μm glucosinolate/g oil free meal) characteristics in B. juncea var. Varuna.
