Online published on 30 November, 2019. Abstract Survey and screening of different cultivars of roses for their resistance and susceptibility against rose aphid (Macrosiphum rosae) were undertaken in Srinagar and Baramulla and Floriculture Field Division of FMAP, SKUAST-K, Shalimar. Survey was carried out in two districts of Kashmir valley from March to December, 2007 on the incidence of rose aphid. The per cent incidence and number of aphids twig−1 were high in Srinagar district at all the five locations surveyed, while these were lower in Baramulla district at all the locations except Pattan. The pest activity was 10 months at district Srinagar and 9 months at district Baramulla. Screening of rose cultivars for their resistance against aphid (M. rosae) revealed that Grand Gala and Nobless harboured maximum mean aphid infestation index (MAII), i.e., 1.33 and 1.10, respectively, whereas Golden Gate and Naranga exhibited moderate mean (0.88 & 0.99). The minimum mean aphid infestation index was 0.55 in Konifittii. Top Keywords Survey, cultivars, rose aphid, screening. Top |
