KG Shete, BV Patil and SD Bantewad
An investigation on screening of Advanced Varietal lines against major pests (leaf miner (Aproaerema modicella, Deventer), leaf eating caterpillar (Spodoptera litura, Fabricius) and green semilooper (Chrysodeixis acuta)) of soybean was conducted at Research Farm, Department of Agricultural Entomology, College of Agriculture, Badnapur during Kharif season 2017 in Randomized Block Design (RBD) with 14 AVT lines and two replications in protected and unprotected set of conditions. The lowest infestations of leaf miner was recorded on line RVS 2007-6, KDS-1045 and check JS 97-52 while the highest infestation recorded on line DSB-28-3, RVS 2010-1 and MAUS-2. The lowest S. litura larvae recorded on line KDS-1045, KDS-980 and check MAUS-158 and JS 97-52 while the highest larvae observed on line DSB-28-3 and check JS-335.The lowest C. acuta larvae were recorded on line KDS-921, RVS 2007-6, KDS-1045 and check MAUS-158 while the highest C. acuta were observed on line AMS-MB-5-18, DS-3105 and check MAUS-2.
Under unprotected condition the highest grain yield was obtained in line DS-3105, AMS-MB-5-18, check MAUS-158 and JS-335 while the lowest yield were obtained in line KDS-1045.Under protected condition the highest yield were recorded in DS-3105, RSC-10-70 and check JS-335.
