Effect of genotypes, reproductive developmental stages, and environments on glucosinolates content in rapeseed mustard

The current study reports changes in glucosinolate content in rapeseed mustard at different floral developmental stages. Variation in glucosinolate content seems to be primarily under control of reproductive developmental stages, which contribute to 47.18- 69.98% of total variance. Significant differences were found in glucosinolate content among 10 different genotypes of rapeseed mustard. Glucosinolate content was higher in protected than unprotected environment. Although significant stage x environment and stage x genotype effect was observed, these effects were small as compared influence due developmental stage and genotypes. Total glucosinolate content increases from flower initiation stage (FIS) to full bloom stage (FBS) while at pod maturity stage (PMS), it tends to decrease.
