Vulnerável, devido ao uso excessivo do limoeiro ‘Cravo’ (Citrus limonia) na sustentação de seus pomares, exige urgência em um programa de diversificação de porta-enxertos. Nesse sentido, a Embrapa Mandioca e Fruticultura Tropical vem executando, no Recôncavo Baiano, um programa de hibridações visando a criar novas variedades, principalmente porta-enxertos, adaptadas a diferentes regiões geográficas do País, com ênfase no Nordeste. Considerando os caracteres altura da planta e diâmetro do caule, foram analisados 554 seedlings (plantas oriundas de sementes ou pés-francos) híbridos, dentro de 38 progênies obtidas de cruzamentos envolvendo Citrus e gêneros afins, com destaque para Poncirus. Os híbridos foram levados a campo entre agosto de 1995 e julho de 2000, em conformidade com as épocas de suas obtenções. O citrangeiro (C. sinensis x P. trifoliata) ‘Argentina’ destacou-se como importante parental masculino na produção de híbridos. As tangerineiras ‘Sunki (C. sunki) Comum’, ‘Sunki da Flórida’, ‘King’ (C. nobilis), ‘Clementina (C. clementina) de Nules’ e ‘Clementina Palazelli’ podem dar formação a progênies vigorosas. Seedlings híbridos de ‘Sunki’ e ‘King’ podem ser tão ou mais vigorosos que seedlings nucelares dessas tangerineiras.

    THE EVOLUTION OF THE AMERICAN LEMON-GROWING INDUSTRY* RoBERT W. DuRRENBERGER San Fernando Valley State College Nearly one-third of all the lemons grown in the world come from a few fruit-growing districts in Sm.1thern California. Average annual produc­ tion over the past ten years has been about 15,000,000 boxes per year.1 The only other major producing area in the world, Italy, has averaged around 14,000,000 boxes/er year.2 The production of the principal lemon-growing areas of the worl is shown in Table 1.

On the basis of value of production lemons rank fifteenth among the agricultural commodities in the State of California. In the eight most im­ portant lemon-producing counties lemons usually account for ten per cent or more of the total value of agricultural production (Figure 1). In Ventura County (Figure 2) the lemon is the most important commodity produced and generally accounts for over one-third of the total value of all agricul­ tural products grown within the county." (Table 2) This impressive position in the production of lemons is the result of a remarkable growth of the industry over the past one hundred years.

Bitters Professor of Horticulture, Emeritus Riverside 1915-2006 Born in Eau Claire, Wisconsin, in June, 1915, Dr. Willard “Bill” Bitters earned his bachelor’s degree in biology from St. Norbert College and his master’s degree and Ph.D. from the University of Wisconsin. After earning his doctorate, he first worked as the superintendent of the Valley Research Farm of the University of Arizona in Yuma, and joined the Citrus Experiment Station, in Riverside in 1946 as a Horticulturist. In 1961, Dr. Bitters became a Professor in the newly established University of California-Riverside. His initial assignment was to work on horticultural aspects of tristeza, a serious vector-transmitted virus disease which threatened to destroy California citrus orchards. Tristeza was already in California and spreading in 1946. At that time most citrus trees in California were grafted on a rootstock that was known to be susceptible to tristeza. Dr. Bill Bitters was responsible for screening of over 500 cultivars to determine which rootstock-scion combinations were resistant to this disease and yet possessed suitable horticultural characteristics. Of the 500 screened, most were susceptible, but several successful ones were selected and released to the industry.

  • Herbert John Webber 1865—1946
    California Avocado Society 1946 Yearbook 30: 128-129 Herbert John Webber 1865—1946 In Memorium Herbert John Webber was born December 27th, 1865 at Lawton, Michigan. After graduating from the University of Nebraska, he later received the degree of PhD from Washington University. He was most interested in the science of living plants. In 1892, while in the service of the United States Department of Agriculture, he was sent to Eustis, Florida. There, in collaboration with W. T. Swingle, he produced many citrus hybrids among which the Sampson Tangelo is most familiar to Californians. Many other subtropical fruits attracted his attention, and there he made his first acquaintance with the avocado. After serving five years as Professor of Plant Breeding at Cornell University, he was called to Riverside California to become Director of the University of California Citrus Experiment Station; where, with short interruptions for cotton breeding work in South Carolina, and a citrus survey in South Africa, he served until his retirement in 1936. Dr. Webber took an active part in the organization of this Society in 1915, served as director 1915 to 1920; as President in 1916, and again as director from 1935 to 1937. In the early days he was very active on the variety committee, and in many ways did much to advance the best interests of the avocado industry. Dr. Webber served on the committee of minor subtropical fruits and was particularly enthusiastic with respect to the future of the guava as a commercial fruit. He frequently contributed to the Yearbook of this Society. He was awarded the Society Emblem of Honor in 1938.
