Field screening of soybean genotypes against green semilooper, Chrysodeixis acuta (Fabricus)

The field experiment was carried out at Soybean Research Farm of Birsa Agricultural University, Ranchi during Kharif 2021 and 2022 with 35 genotypes along with two check genotypes. The pooled data of two consecutive years revealed that on the basis of overall pooled mean, Chrysodeixis acuta infestation ranged from 0.76 to 1.44 larvae/mrl. Among all the tested genotypes the least larval infestation was recorded in genotype BAUS-110 and it was followed by RCS-10-46 (0.80 larvae/mrl) which remained statistically at par with genotype BAUS-124 (0.84 larvae/mrl) and BAUS-118 (0.90 larvae/mrl). Whereas, maximum larval infestation was observed in BAUS-122 (1.44 larvae/mrl) which was at par with BAUS-115 (1.43 larvae/mrl). The results also showed that for the Kharif 2021, five genotypes viz., BAUS-110, BAUS-96, RCS-10-46, BAUS-18 and BAUS-120 were found to be highly resistant while in 2022, genotype BAUS-124 was found highly resistant whereas BAUS-110 and RCS-10-46 were found to be resistant.
