Abstract: |
Pepper (Capsicum annuum L and C. fruitescens L.) is an important high value crop grown for vegetable and for spice purposes. Phytophthora blight caused by Phytophthora capsid Leoni an is a serious disease of pepper causing foliar blight, fruit rot and crown/root rot phases. Crown/root rot phase is the most devastating phase of the disease. Experiments were conducted with the objective to find resistant/tolerant varieties against phytophthora blight disease. Seedling evaluations were carried out in inoculated conditions under screenhouse during 2007-2009. inoculum of zoospore suspension of 1oM spore/ml was used at the rate of 25 ml per plant at 5 week old stage of seedling. Based on the terminal disease incidence (5-7 weeks after inoculation), NS 1701, Chandani, Tara, Angarika and Premium were found resistant in seedling assay. During 2010 and 20/1, on-farm evaluation .of selected genotypes (1 1-1 3) was carried out in the farmers' field with the history of Phytophthora blight in chilli pepper. The experiment was conducted in hVo replications each with 16 plants. NS 1701, Tara, Angarika and Chandani were found resistant. Other genotypes NS 214, NS 1101, Go/i and Premium were moderately resistant. Lesser fruit rot was found in Angarika, NS 1701, Long Wei and Pusa Jwala compared to other varieties. Those resistant to moderalely resistant genotypes could be used as one of the tools of integrated disease management ofphytop/lthora blight in disease prone areas to minimize crop/yield losses. |
