Pattern of genetic diversity among Fusarium wilt resistant castor germplasm accessions (Ricinus communis L.)
نویسنده
چکیده
Wilt caused by Fusarium oxysporum f.sp. ricini (Wr) Gordon is one of the major yield losing diseases in castor. Cultivating wilt resistant cultivars is an effective strategy to control the disease. Utilization of diverse sources of stable resistance is a prerequisite for durable resistance breeding. The experiment was conducted to identify genetically diverse resistant sources in castor germplasm. Genetic diversity among 20 identified wilt resistant germplasm was assessed using multivariate classificatory methods. Wide genetic diversity was demonstrated among these accessions. These accessions are valuable in wilt resistance breeding programme. They would serve as base diverse material for wilt resistance breeding, wilt resistant genepool construction and molecular tagging of resistant genes.

Genetic analysis of castor (Ricinus communis L.) using ISSR markers
Castor (Ricinus communis L.) is one of the most ancient medicinal oil crops in the world. It has been vastly distributed in different parts of Iran. In the present study, the inter simple sequence repeat (ISSR) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of Iran. Totally, 16 ISSR primers amplified 166 loci...

Wilt, caused by Fusarium oxysporum f. sp. ricini, is the most severe disease of castor bean (Ricinus communis). For the development of marker for wilt-resistant gene, 200 F2 individuals from a cross between the resistant cultivar 48-1 and the susceptible cultivar VP-1 were inoculated with a race of Fusarium oxysporum f. sp. ricini. Bulked segregant analysis was used to search for random amplifi...

Castor (Ricinus communis L.) is an important non-edible oilseed crop that can potentially be used as feedstock for biodiesel production. There are 1033 accessions in the United States Department of Agriculture (USDA) castor germplasm collection. The range of oil content in these accessions has never been surveyed. For exploiting castor as a feedstock for biodiesel production, the entire USDA ca...

Objective: Castor (Ricinuscommunis L.) is an industrial oilseed that belongs to the family Euphorbiaceae. Castor is believed to be originated in East Africa probably Ethiopia. Although Ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. The present test was conducted to study the nature and extent o...
