Screening of selected kenyan soybean varieties for resistance to Phakopsora pachyrhizi (Soybean rust)
Abstract
Soybean (Glycine max (L.) Merrill.) is a highly nutritious plant which plays an important role in the world’s economy, however soybean rust disease caused by the fungus Phakopsora pachyrhizi, is a major challange to the soybean industry. The disease among other constraints has significatly affected crop yields in most soybean growing countries. In this study Seven varieties of soybean (Nyala, Bossier, SB19, Hill, SB8, Gazelle and TGx1987-32F) commoly grown by farmers in Kenya were tested in the green house for resistance to soybean rust. The varieties TGx1987- 32F and SB8 showed resistant reactions characterized by red brown lesion with low level of disease severity, low lesion number, low sporulation level and low area under disease progress curve (AUDPC) value. The other five varieties; Nyala, Bossier, SB19, Hill and Gazelle showed susceptible reactions to soybean rust producing tan lesion with profuse sporulation and high disease severity level. The Soybean varieties with low lesion densities, low disease severity and low sporulation level may be possible sources of rust resistance genes that can be used in breeding programs to produce rust resistant varieties.
