Download or read book Global Plant Genetic Resources for Insect-Resistant Crops written by Stephen L. Clement and published by CRC Press. This book was released on 2019-04-23 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: An excellent reference book for plant breeders and entomologists, Global Plant Genetic Resources for Insect-Resistant Crops combines germplasm preservation with use in insect-resistant crop development and basic research. The contributions of the authors represent the efforts, cooperation, and understanding of world leaders in the conservation and use of global plant genetic resources for sustainable agricultural production. Concepts addressed include dependency of modern agriculture on chemical pest control and applications of biotechnology in use of natural plant genes for insect-resistant crops.

Book Synopsis Assessment of Resistance and Inheritance to Barley Yellow Dwarf Virus Disease (BYDV) in Five Wheat Cultivars (Triticum Aestivum L.) by : Jaime Tola
Download or read book Assessment of Resistance and Inheritance to Barley Yellow Dwarf Virus Disease (BYDV) in Five Wheat Cultivars (Triticum Aestivum L.) written by Jaime Tola and published by INIAP Archivo Historico. This book was released on 1983 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification of sources of resistance; and 3) determination of the nature of inheritance controlling BYDV resistance. Five wheat cultivars with possible different levels of resistance to BYDV and the resulting F1, F2, F3, BC-1 and BC-2 populations provided the experimental material. An assessment of the damage inflicted by aphids feeding per se and aphid plus virus on the five cultivars was determined under greenhouse conditions. Cultivars and the resulting progeny were grown in the field to confirm the greenhouse findings and to determine nature of inheritance. Aphid feeding per se did not influence most cultivars other than for plant height involving Yamhill and Anza. Despite the lack of visual symptoms, BYDV did significantly influence the six parameters measured with the cultivars Stephens and Riebesel exhibiting the greatest reduction. No immunity was observed for any of the cultivars tested. Under field conditions Stephens, followed by Riebesel, were the most susceptible cultivars with Yamhill, Novi Sad and Anza being the most resistant based on the parameters measured. The inheritance pattern appeared to be quantitative with both additive and nonadditive genetic variability involved in controlling resistance. This was verified by the transgressive segregation noted in F2 and F3 generations and the significant General and Specific Combining Ability estimates for the BYDV score. Due to the quantitative nature of BYDV resistance and the different genetic factors observed for the cultivars in this study, a recurrent selection program should result in higher levels of resistance than exhibited by the cultivars employed in this study. Also, the use of a visual BYDV score appears to be an effective means of identifying resistant parents.
