DOI:10.5958/2230-732X.2015.00116.3
Abstract:
Different genotypes of Rajmash were sown at Agricultural Research Farm of Banaras Hindu University during Rabi season of 2013-14 and 2014-15 for the evaluation of resistance to leaf miner and pod borers. During 2013-14 genotype 405 showed comparative resistance reaction to leaf miner damage (33.52%), whereas genotypes HUR 15 (51.74 %) and 180 (51.10 %) showed susceptible reaction with higher leaf miner damage. Maximum pod damage was recorded in genotype VL63 (11.00 %) and minimum in HUR 203 (1.93 %). Genotype M8 produced higher yields as compared to other genotypes (13.88 q ha-1), while genotype 180 (5.86 q ha-1) produced minimum yield. During 2014-15, genotype 405 (26.16 %) showed less leaf miner damage and genotype HUR 15 (45.12 %) was more infested by leaf miner. Genotype VL63 (11.67 %) showed maximum pod damage and genotype 405 (3.94 %) showed less damage.Maximum yield obtained from genotype 214 (13.36 q ha-1) and minimum from genotypes HUR15 and HUR 146 (6.48 q ha-1).
