Abstract:

Resistance against insect pests is a crucial trait for the stability and sustainability of pigeonpea production. A field trail was conducted to quantify relative tolerance and sensitivity in9 new long duration pigeonpea genotypes including local control against pod fly during Kharif2017-18 at the Entomological Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. In general, it was observed that none of the genotypes were found completely resistant to pests although these originated as least susceptible, moderately susceptible and highly susceptible. Of them, JKM 189 was rated as more tolerant to pod fly attack in comparison to Bahar (check) that appeared susceptible. The mean populations of pod fly among the genotypes ranged from 1.65 pod fly maggots/ plant in JKM 189 to 2.18 pod fly maggots/plant in Bahar (check). On the basis of per cent pod and grain damage values, the genotype JKM 189, CRG 2015-007 and LRG 208 less pest pressure than Bahar, BDN 2014-2 and BAUPP 15-22 which were the most susceptible. Differences in grain yield were also observed, indicating that minimal and maximal pest injury on pigeonpea influenced the crop yield. The genotypes JKM 189, CRG 2015-007and LRG 208 performed well in respect of higher grain yield. The results suggest that tolerant pigeonpea genotypes might be commercially cultivated extensively in this agro-climatic area and Scientists involving in development of host plant resistant cultivars are encouraged to utilize resistance sources as donar against key pest species.
