YIELD PERFORMANCE of RADIATION INDUCED RAPESEED MUTANTS at M8 GENERATION

Abstract


Rapeseed is the most potential oilseed crop of Indian sub-continent. So higher seed yield potential variety is a central choice of rapeseed grower. To verify the yield performances of rapeseed mutants an experiment was conducted at various locations of Bangladesh. Four true-breeding (homozygous) mutants obtain from three different radiation doses (600, 800 and 900 Gy) along with the mother variety BARI Sarisha-15 and check variety BARI Sarisha-17 were used for each condition. The experiment was laid out in a randomized complete block design with three replications. Interaction between genotype and location showed significant variations for all the agronomic traits, whereas only non-significant variations were provided from branch plant-1 and siliquae length for location. Mutant RM-20 produces the highest plant height (101.1cm) and matures earlier than all other mutants parent and check. At Magura and Ishurdi all the mutants produce a significantly higher number of siliquae plant-1 than parent BARI Sarisha-15 and check BARI Sarisha-17. RM-18 and RM-20 produce maximum seeds siliquae-1 (30) whereas the mutant RM-07 produced the lowest number of seeds siliquae-1 (22). Combined means over locations showed that mutants namely RM-18 and RM-20 produced significantly higher seed yields (1551.1 and 1385 kg/ha, respectively). This suggests that gamma rays irradiation can be fruitfully applied to develop mutants with higher seed yield and other agronomic traits in rapeseed.
