Crop Losses from Pea Seedborne Mosaic Virus in Six Processing Pea Cultivars

Abstract

Field responses of six processing pea cultivars to pea seedborne mosaic virus were tested in an isolated location near Prosser, WA, in 1977 and 1978. Test plots were mechanically inoculated either 2 or 3 wk after emergence. Disease incidence, determined visually on a per plant basis, was higher in all plots in 1977 than in 1978 and generally corresponded with rate of seed transmission and loss in green pea and seed yields. The later maturing, more determinate cultivars (Mars, Conway, and Corfu) were more severely affected than earlier maturing, indeterminate cultivars (Small Sieve Alaska and A-45) in both years. Losses in green pea and seed yields in 1977 were greater in plots of all cultivars inoculated 2 wk after emergence than in those inoculated 3 wk after emergence. Pea seedborne mosaic virus (PSbMV) is a continuing threat to the pea (Pisum sativum L.) seed and processing industry in the United States (12,17,20,22).

Control of Plant Virus Diseases in Cool-Season Grain Legume Crops

“…Examples of quantitative estimates of seed yield losses from field experiments with natural spread include ones with CMV and BYMV in lupin where yield losses of up to 66% occurred (Bwye, Jones, & Proudlove, 1994;Jones, 2001;Jones, Coutts, & Cheng, 2003), CMV in chickpea where yield losses were up to 80% ( Jones, Coutts, Latham, & McKirdy, 2008), and PSbMV in pea where yield losses of up to 25% occurred (Coutts, Prince, & Jones, 2009). Yield losses from field experiments with other combinations of virus and cool-season grain legume crops are given by Alkhalaf, Kumari, Haj Kasem, Makkouk, and Al-Chaabi (2010), Boswell and Gibbs (1983), Bos et al (1988), Cockbain (1983), Franz, Makkouk, and Vetten (1997), Kraft and Hampton (1980), Kumari and Makkouk (1995), , Makkouk, Kumari, and Bos (1993), and .…”

Sequence tagged site markers linked to the sbm1 gene for resistance to pea seedborne mosaic virus in pea

“…Pea seed-borne mosaic virus (PSbMV) is an economically important pathogen that causes disease on peas, lentils and broadbeans. In peas, significant yield losses can result from infection by PSbMV (Kraft and Hampton 1980), which is spread by non-persistent aphid transmission and through planting infected seed. PSbMV results in marking of the seed with typical Ôtennis ballÕ lesions and reduces seed size, resulting in loss of seed quality.…”

Studies on resistance of pea to pea seed borne mosaic virus and new pathotypes

“…Pea seed borne mosaic virus (PSbMV) is a widely distributed virus of pea on which it provokes considerable yield losses (Kvicala, Leskova & M u d , 1973; Chiko & Zimmer, 1978; Kraft & Hampton, 1980: Khetarpal et al, 1988. As an alternative to seed certification which controls the disease at the level of primary source of inoculum, a programme of developing resistant varieties is being undertaken.…”
