Abstract
Field studies were conducted at Potato Research Farm, Battakundi (upper Kaghan valley) to evaluate eight Pea cultivars for yield potential against Powdery mildew during summer 2011. The disease severely infected the cultivars “Spring and Strike” up to the maximum at each side. Six cultivars were found resistant and two susceptible to the disease. Among the resistant cultivars, cultivar “Misty” out yielded with fresh Pod yield of 10.55 tons/ha followed by cultivars Legacy, Climax, Tops, Green cross Advinta giving fresh Pod yield of 10, 8.89, 7.09 and 6.48 tons/ha, respectively.
Highlights
Pea Pisum sativum (L) belongs to family Papilionaceae and is an important leguminous crop
Owing to favorable weather conditions and use of susceptible pea cultivars crop is damaged by powdery mildew in Kaghan valley (Jan, 1996, 1999)
Data were collected in respect of Days to germination, Days to flowering, Plant height, Powdery mildew score, Days to pod formation, No of pods/plant, No of grains/pod and Fresh pod yield (Tons/ha)
Summary
Pea Pisum sativum (L) belongs to family Papilionaceae and is an important leguminous crop. In Pakistan it is an important vegetable crop and is cultivated in Khyber Pakhtunkhwa both as a summer and winter crop with higher yield than Sindh and Balochistan. In Kaghan valley of Pakistan, Pea is grown in off season as a rotational crop for potato since 1989. Owing to favorable weather conditions and use of susceptible pea cultivars crop is damaged by powdery mildew in Kaghan valley (Jan, 1996, 1999). A white powdery coating on surface of leaves stems and pods of mycelium of the fungus Erysiphe polygoni DC (Singh, 1978; Bilgrami and Dube, 1982; Agrios, 1988; Kazmi et al, 2002) characterize this disease. The fungus is spreads by air currents; rain can controls the disease by washing spores and making it burst (Hargedorn, 1991)
