Available in PDF, EPUB and Kindle. Book excerpt: Twenty-four corn inbreds, selected for resistance to gray leaf spot (caused by Cercospora zeae-maydis) in 1989 and 1990, were crossed with the susceptible inbreds FR1141 and/or FR20 and populations of four to six generations were produced. In 1991, the populations were evaluated for gray leaf spot severity at Urbana, Illinois and at Andrews, North Carolina. Using generation mean analysis, additive genetic effects were found significant for most populations and dominance effects were found significant for eight populations. Significant parameter estimates for dominance effects were negative indicating dominance for resistance. Five inbred lines 061, 198, B37HtN, DS:74:1071, and (OH43x#8brbr) were selected for further evaluation based on their level of resistance, results from the generation mean analysis, and maturities useful for breeding in Central Illinois. The five inbred lines selected in 1991 were crossed with FR1141. The inbreds 061, B37HtN, and (OH43x#8brbr) also were crossed with the inbreds FR20, B37, and OH43 respectively. Eight populations of six to nine generations were produced from these crosses and evaluated for gray leaf spot severity in 1992 and 1993 at Urbana, Illinois and Andrews, North Carolina. Individual plants were rated for gray leaf spot severity by visually estimating the percent leaf area blighted in August and again in September. Analyses of variance indicated significant interactions between generations and environments and rating times for certain populations. Generation mean analyses indicated that pooled additive effects and pooled dominance effects were adequate to explain the inheritance of resistance for three populations, FR20 x 061, FR1141 x (OH43x#8brbr), and OH43 x (OH43x#8brbr). For the other populations there were significant deviations from the additive-dominance model at certain year-location-rating time combinations. For the FR1141 x DS:74:1071 population, additive effects were most important. Significant dominance effects were most frequently detected at early rating times and were most important for the FR1141 x 061, FR1141 x 198, FR1141 x (OH43x#8brbr), and OH43 x (OH43x#8brbr) populations. Epistatic effects were most important for the B37 x B37HtN population. Based on the level of resistance, heritability estimates, and estimates of effective factors for these populations, genes for resistance from these inbred lines should be useful in improving corn belt germplasm for resistance to gray leaf spot.

Available in PDF, EPUB and Kindle. Book excerpt: From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.

Available in PDF, EPUB and Kindle. Book excerpt: Studies in the Agricultural and Food Sciences: Plant Breeding for Pest and Disease Resistance presents a critical review of the development of resistant varieties of plant to pests and diseases. It discusses the economic impact of pests and diseases; the methods of controlling these pests and diseases; and the challenges being faced by a plant breeder. Some of the topics covered in the book are the general principles and methods of breeding for resistance; importance of parasite variability to the plant breeder; methods of testing for resistance; requirements for successful inoculation; production of resistant varieties; and economic importance of fungal diseases; and variability in fungal pathogen. Pathogenic fungi and fungal diseases are also covered. The control of fungal diseases by resistant varieties is discussed. An in-depth analysis of diseases in plants is provided. The characteristics of bacteria and bacterial diseases are also presented. A chapter is devoted to epidemiology of diseases associated with mycoplasma-like organisms and rickettsia-like organisms. The book can provide useful information to farmers, botanists, students, and researchers.
