Abstract
The current research trial was conducted at Oilseeds Research Institute (ORI), Faisalabad for resistance/ susceptibility source against a devastating Brassica disease i.e. Alternaria leaf spot. In this field research trial, thirteen (13) varieties/ advanced lines of brassica were assessed during 2019-20 and 2020-21 by adopting statistical design namely RCBD (Randomized Complete Block Design) at the experimental research field of (ORI), Faisalabad under the umbrella of Ayub Agricultural Research Institute Faisalabad. In 2019-20, one advance line viz. RBJ-15013 exhibited resistant response with 8.00% disease incidence with rating 1 while six lines i.e. RBJ-15017, RBJ-16007, RBJ-17003, BRJ-17075, BRJ-17078 and Super Raya expressed moderately resistant reaction under rating 2. Likewise, four varieties/advanced lines exhibited moderately susceptible (MS) response whereas one advanced line KJ-294 expressed susceptible response (rating 4) and KJ-159 showed highly susceptible (HS) response by 85.67% disease incidence with rating 5. During 2020-21 one advanced line exhibited highly susceptible response with (81.70%) disease incidence with rating 5 while one of the advance line i.e. KJ-159 (71.80%) showed susceptible response (rating 4). Similarly, eight advanced lines viz. RBJ-15017, RBJ-17003, BRJ-17075, Super Raya, RBJ-17005, KJ-294, 18CBJ005 and KJ-284 exhibited moderately susceptible (MS) response (rating 3). Likewise, two variety/ advance lines RBJ-15013 and BRJ-17078 exhibited moderately resistant response whereas one of the advanced line i.e. RBJ-16007 (8.47%) showed resistant response (rating 1). It had been concluded that resistant varieties/ advanced lines are the most appropriate and economical disease management approach against Alternaria Leaf Spot Disease of brassica.
