The study was
conducted in the experimental field of Sher-e-Bangla Agricultural
University (SAU), Sher-e-Bangla Nagar, Dhaka, Bangladesh during the
period from November 2015 to March 2016 to evaluate 8 promising
mustard varieties against mustard aphid. The field study was laid out
in a randomized complete block design with three replications. Eight
mustard varieties viz., BARI Sarisha-9, BARI Sarisha-10, BARI
Sarisha-11, BARI harisha-13, BARI Sarisha-14, BARI Sarisha-15, BARI
Sarisha-16 and BARI Sarisha-17 were evaluated against aphid
infestation in respect of plants, leaves, inflorescence and pods to
find out the tolerant variety(ies) against aphid. Out of eight
mustard varieties, BARI Sarisha-14 was found as the most preferred
host for aphid infestation. Whereas BARI Sarisha-13 was the least
preferred varieties for aphid infestation on plants, leaves,
inflorescences, and pods. The most susceptible variety BARI
Sarisha-14 produced the lowest grain yield ha-1 (405±6.45). The
least susceptible variety BARI Sarisha-13 produced the highest grain
yield ha-1 (678±2.67).
Key words: Mustard
and mustard aphids.
