Broadening Gene Pool of Rice for Resistance to Biotic Stresses Through Wide Hybridization
Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...
متن کاملStudies on the biotic Stress Resistance in Rice through Molecular Markers and Six Population Analysis
Rice (Oryza staiva L.) is one of the world's most important crops, providing a stable food for nearly half of the global population (FAO 2004). Almost 90% of the rice is growing and consumed in Asia. The striped stem borer (Chilo suppressalis Walker) is one of the most important rice pests in Asia. Rice stem borers cause damage to the crop at the larval stages. Larvae borer in to the plant stem...
متن کاملEvolutionary and social consequences of introgression of nontransgenic herbicide resistance from rice to weedy rice in Brazil
Several studies have expressed concerns about the effects of gene flow from transgenic herbicide-resistant crops to their wild relatives, but no major problems have been observed. This review describes a case study in which what has been feared in transgenics regarding gene flow has actually changed biodiversity and people's lives. Nontransgenic imidazolinone-resistant rice (IMI-rice) cultivars...
متن کاملAnalysis of Stress-Responsive Gene Expression in Cultivated and Weedy Rice Differing in Cold Stress Tolerance
Rice (Oryza sativa L.) cultivars show impairment of growth in response to environmental stresses such as cold at the early seedling stage. Locally adapted weedy rice is able to survive under adverse environmental conditions, and can emerge in fields from greater soil depth. Cold-tolerant weedy rice can be a good genetic source for developing cold-tolerant, weed-competitive rice cultivars. An in...
متن کاملQTL Analysis for Resistance to Blast Disease in U.S. Weedy Rice.
Understanding the genetic architecture of adaptation is of great importance in evolutionary biology. U.S. weedy rice is well adapted to the local conditions in U.S. rice fields. Rice blast disease is one of the most destructive diseases of cultivated rice worldwide. However, information about resistance to blast in weedy rice is limited. Here, we evaluated the disease reactions of 60 U.S. weedy...
