..................................................... 141 ACKNOWLEDGEMENTS ....................................................................................... 146 vi ABSTRACT The maize (Zea mays L.) in vivo maternal doubled haploid system has been widely applied to maize breeding and genetics in recent decades and is an important part of the majority of public and private maize breeding programs today. The principal advantage of the doubled haploid system is the ability to generate completely homozygous inbred lines in as little as two seasons. Other advantages to this system include more rapid integration of loci of interest and increased usefulness over traditional lines developed through self-pollination. In this dissertation, some of the major problems in the maternal doubled haploid system are addressed. Namely, improvement of maternal inducers, improved understanding of the genetics controlling inducibility, development of an automated system to sort haploid kernels, investigation and application of spontaneous chromosome doubling, and a proposal for the acceleration of the breeding cycle beyond doubled haploids through the in vitro nursery. This dissertation provides some new insight into these problems, as follows. The development and release of a new improved maternal haploid inducer for use in doubled haploid programs. Improved understanding of the quantitative nature of inducibility and the effects of misclassification are discussed. Successful automated discrimination of haploid and diploid kernels using optical and fluorescence methods is described. In

  • Maize Variety Choices and Mayan Foodways in Rural Yucatan, Mexico
    All Maize Is Not Equal: Maize Variety Choices and Mayan Foodways in Rural Yucatan, Mexico John Tuxill, Luis Arias Reyes, Luis Latournerie Moreno, and Vidal Cob Uicab, Devra I. Jarvis Introduction Foodways have changed substantially over the past several centuries in the Yucatan Peninsula and other areas of Mesoamerica, but one constant is the presence of maize (Zea mays) at the heart of rural economy, ecology, and culture. The domes- tication and diversification of maize – the world’s most productive grain crop – by indigenous farmers ranks as one of the greatest accomplishments of plant breeding. Remains of ancient maize cobs in the archeological record suggest that maize was first brought into cultivation roughly 7,000 years ago in the highlands of central Mexico, where its closest wild relative, teosinte (Zea mays ssp. parviglumis), also grows (Wilkes 1977; McClung de Tapia 1997; Smith 2001; Piperno and Flannery 2001; Matsuoka et al. 2002). From that starting point, maize was gradually selected and diversified over time by farmers into an impressive array of different forms, sizes, and colors. Maize appears to spread out of central Mexico rapidly in the context of regional trade and exchange networks, and farmers selected and adapted maize populations to thrive in new environments. Archeobotanical evidence from northern Belize suggests maize arrived in the Yucatan Peninsula by about 5,000 years B.P. (Colunga-García Marín and Zizumbo-Villarreal 2004). As maize spread and evolved in the Yucatan at the hands of Mayan farmers, it achieved a symbolic, ceremonial, ecological, and economic importance surpassing that of any other plant or natural resource in the Mayan world.

    THE NORTH AMERICAN SPECIES OF NYMPHA EA. By GERRIT S. MILLER, Jr., and PAUL C. STANDLEY. INTRODUCTION. NOTE BY ;T. N. ROSE. There are some groups of plants whoso taxonomy can bo fairly well understood almost solely from ordinary herbarium material. There are others in which it is impossible to understand the true relationships from such material alone, anrl some evon in which herbarium specimens are almost useless. Among the last are the Cactaceae, many of the tropical Euphorbias, the Crassulaceae, and in general all the succulent plants. To be properly understood such plants should be soon growing, or should be studied from material preserved in alcohol or formalin, since in dry specimens most of the important characters are distorted beyond all possibility of recogni­ tion. Among plants of this kind the Nymphaeaceae must be included. Most of our knowledge of the genus Nymphaea, judging from the literature of the North American species at least, has heen derived from the study of dried herbarium material. As a result, different authors have arrived at very different conclusions. Impor­ tant peculiarities of habit Ilnd strueture not discernible in such specimens have been overlooked, and our knowledge of the genus has not kept pace with the advances made in some other groups. About ten years ago Mr. Gcrrit S. Miller, jr., became interested in the genus Nymphaea from field observations of the plants occurring in central New York and in the vicinity of Washington, currently regarded as belonging to one species. Study of fresh and forlllalin­ preserved material showed that there were important and easily recognizable differences between the northern form and that found farther south, differences in habit, color, and structure, scarcely to be detected in dried specimens.
