New Hosts

Powdery mildew occurred widely on faba beans (Vicia faba L.) in Manitoba in 1974. Mycelia, and conidia were abundant on both leaf surfaces. The fungus later developed numerous cleistothecia 99–143 μm in diam, with rigid appendages, 128–286 μm in length, dichotomously branched at their apices and ending in recurved tips. Frequently, appendages were contorted and irregularly branched. Cleistothecia contained 5–8 asci. The fungus produced mildew symptoms on Lathyrus ochroleucus Hook., L. odoratus L., L. latifolius L., and Vicia americana Muhl., but failed to infect Lonicera tatarica L., Pisum sativum L., and Syringa vulgaris L. The fungus was identified as Microsphaera penicillata (Wall. ex Fr.) Lév. var. ludens (Salmon) Cooke on the basis of morphological characters and pathogenicity. Lathyrus spp. are new hosts of the fungus. L. ochroleucus and V. americana may be sources of primary inoculum of the fungus in Manitoba. Erysiphe pisi DC. reported to occur on V. faba was not found on any of the specimens.

The efficacy of sulfur (Kumulus S) and myclobutanil (Nova 40W) fungicides for control of powdery mildew (Erysiphe pisi Syd) in field pea (Pisum sativum L.) was investigated in field trials at two locations in Manitoba in 1994 and 1995. Both fungicides were effective in reducing disease seventy and increasing seed yield and seed weight of the susceptible cultivar Radley. Fungicide treatments were economically beneficial when disease pressure was high. Key words: Field pea, Pisum sativum L., powdery mildew, Erysiphe pisi Syd., sulfur, myclobutanil

High Yield Potential

The yield potential, quality and level of resistance to powdery mildew (Erysiphe pisi DC.) of afila smooth seeded pea (Pisum sativum L.) were tested in the field trials. The cultivars and breeding lines Mozart, Consort-R, AGT-01, Cebeco 1171 and AGT-GH surpassed the control cv. Gotik in the yields of dry seed, in contrast the dry seed yields of Highlight, AGT-KR, Melfort and LU 390-R2 were about 12–27% lower than that of the control. The low seed yield was caused by virus infections (PEMV, BYMV), root diseases (Pythium, Fusarium), and a low level of thousand seeds weight (TSW). Material crossing with donors possessing high yield potential, a higher TSW, and a higher tolerance to root diseases had a positive effect on the dry seed yield. The main objective of the resistant pea breeding programme is afila smooth seeded pea resistant to powdery mildew, with a high tolerance to viruses, root diseases, and lodging, with the stem length of 60 to75 cm, and with high yield potential.
