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.

Download or read book Triticale Today and Tomorrow written by Henrique Guedes-Pinto and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 837 pages. Available in PDF, EPUB and Kindle. Book excerpt: Triticale's days as a scientific curiosity are definitely over. Its wide acceptance as a feed, grain or forage crop, or for baking and malting, plus its high yields under marginal or stress conditions have made it an economically important crop in countries such as Poland, Germany, Australia, Portugal, Brazil, Morocco and China. This publication contains selected, reviewed, and up-to-date papers presented at the Third International Triticale Symposium held in Lisbon, Portugal, by the International Triticale Association and EUCARPIA. Among the broad spectrum of subjects addressed in these presentations are cytogenetics, biotechnology, genetic resources, breeding, agronomic practices and diseases. Also included are triticale's food, feed and forage uses, as well as its marketing processes. In a world of increasing population and decreasing agricultural resources, triticale offers a genuine solution for increasing land utilization and grain production.
