“…Out of 16 accessions of A. moschatus screened for jassids, only IC141055 and IC140986 were resistant. Present findings were in accordance with Prabhu et al (2009) and Dharavath et al (2016). Hooda and Dhankhar (1992) and Singh et al (2007) who reported that the species A. moschatus due to its laminal hairiness was found to be highly resistant to hopper.…”

“…Resistance of A. moschatus might be attributed to presence of dense hairs on stem, upper and lower surface of leaves. Availability of whitefly resistance among wild relatives was also reported earlier by Dharavath et al (2016), Prabhu et al (2009) and Narayanan et al (2016). Borad et al (1993) and Pun et al (2005) reported a highly significant positive correlation between adult whitefly population density and the incidence of BYVMV disease in okra.…”

Okra [Abelmoschus esculentus (L.) Moench] is an important vegetable of which India is the leading producer, but its yield potential is hampered due to Bhendi Yellow Vein Mosaic Virus (BYVMV) disease and insect pests like whitefly, leafhopper, and shoot and fruit borer. The present study was done to identify the stable sources of resistance. Total 44 accessions of 6 wild Abelmoschus species and 2 check cultivars of A. esculentus (Pusa Sawani and Pusa A-4) were screened under natural field conditions at Division of Vegetable Science, ICAR-IARI, New Delhi during kharif season 2015. Both the check varieties were found susceptible to BYVMV, Jassids, whiteflies, and shoot and fruit borer. Out of 44 accessions of 6 wild Abelmoschus species, 3 accessions, viz. IC306722, IC90476-1 and IC141055 were found highly resistant to BYVMV, only two accessions, viz. IC141055 and IC140986 were resistant to Jassids and only one accession 141055 was resistant to whiteflies. While all the accessions of A. tuberculatus and more than 50% of the accessions of A. manihot var. tetraphyllus and A. moschatus were found resistant to fruit borer. However, one of the wild accession IC141055 showed multiple resistance, i.e. Jassids, whiteflies and fruit borer along with resistance to BYVMV disease indicated its possible importance as source of multiple biotic stress resistance. The mentioned promising accessions can be further screened at different hotspots for confirmation and can be exploited in future breeding programmes for okra improvement.
