  • CITRUS BUDWOOD Annual Report 2017-2018
    CITRUS BUDWOOD Annual Report 2017-2018 Citrus Nurseries affected by Hurricane Irma, September 2017 Florida Department of Agriculture and Consumer Services Our Vision The Bureau of Citrus Budwood Registration will be diligent in providing high yielding, pathogen tested, quality budlines that will positively impact the productivity and prosperity of our citrus industry. Our Mission The Bureau of Citrus Budwood Registration administers a program to assist growers and nurserymen in producing citrus nursery trees that are believed to be horticulturally true to varietal type, productive, and free from certain recognizable bud-transmissible diseases detrimental to fruit production and tree longevity. Annual Report 2018 July 1, 2017 – June 30, 2018 Bureau of Citrus Budwood Registration Ben Rosson, Chief This is the 64th year of the Citrus Budwood Registration Program which began in Florida in 1953. Citrus budwood registration and certification programs are vital to having a healthy commercial citrus industry. Clean stock emerging from certification programs is the best way to avoid costly disease catastrophes in young plantings and their spread to older groves. Certification programs also restrict or prevent pathogens from quickly spreading within growing areas. Regulatory endeavors have better prospects of containing or eradicating new disease outbreaks if certification programs are in place to control germplasm movement. Budwood registration has the added benefit in allowing true-to-type budlines to be propagated. The selection of high quality cultivars for clonal propagation gives growers uniform plantings of high quality trees. The original mother stock selected for inclusion in the Florida budwood program is horticulturally evaluated for superior performance, either by researchers, growers or bureau staff.

  • New Citrus Creations of the Department of Agriculture
    NEW CITRUS CREATIONS OF THE DEPARTMENT OF AGRICULTURE. By HERBERT J. "WEBBER, in CMrge of Laboratory of PUmt Breeding^ and WALTER T. SWINGLE, in Charge of Laboratory of Plant Life History, Vegetable Pathological and Physiological Investigations, Bureau Plant Industry, INTRODUCTION. For a period of five years, from November, 1892, to October, 1897, the writers were associated in the study of diseases of citrus fruits in Florida, being located at Eustis, in the central part of the State. A careful study was made of the varieties cultivated and of the industry in general, primarily as a basis for an intelligent investigation of the diseases and methods of their control. In the course of these studies the attention of the writers was early drawn to the desirability of breeding more varied and improved sorts. An examination of the manner of origin of the various native sorts shows that in almost all cases they originated as accidental seedlings. Some growers made hybrids and used systematic methods of breeding, but the number of fruits which have originated in this way are very few indeed. The long time required to bring seedlings to bearing, the cost of cultivation and manuring, and the uncertainty of results have deterred growers from experimenting very extensively in this field. Owing to these difficulties, it seemed from the nature of the case that the investigations should be undertaken by the National Department of Agriculture, in order that the necessary funds could be provided and that the work could be carried on continuously for a series of years. This course was approved, and, under instructions from the Secretary of Agriculture, the writers, under assignment of Dr.

Citrus has a tremendous socio-economical and cultural impact on the whole society. The multifold nutritional and medicinal values make this fruit indispensible in several parts of the world. Citrus is primarily valued for the fruit, which is either eaten alone as fresh fruit, processed into juice or added to dishes and beverages. At the moment, citrus is being grown in Punjab over 52,836 hectares with annual production of 10,49,977 tonnes. Kinnow mandarin occupies an area of 49,356 hectare with annual production of 10,21,719 tonnes. The agro-ecological conditions of Punjab are best suited for the production of Kinnow mandarin. Kinnow cultivation has proved a boon for the farmers due to its higher economic productivity as compared to other fruit crops. The inherited abiotic stress tolerance in Kinnow came from its mother parent King mandarin make this tropical fruit suitable for the sub-tropical region too.

The hearing will be held on August 15, 2018 at 10:00 am, or shortly thereafter, in the Butte County Development Services Conference Room, 7 County Center Drive, Oroville, California. The Butte Creek Diversion 55 Fish Screen Project includes the proposed installation of a retractable and self-cleaning fish screen system at the Butte Creek Diversion 55 (BC 55) site. The existing agricultural diversion is unscreened, and installation of the fish screen system would prevent the entrainment of special-status fish and would help meet the objectives of the Anadromous Fish Screen Program (AFSP). The AFSP is a program designed to protect juvenile anadromous fish from entrainment by encouraging water diversion screening and is administered by the U.S. Fish and Wildlife Service (USFWS) with oversight from the California Department of Fish and Wildlife (CDFW). The site is located northeast of State Route (SR) 99, just southeast of the city of Chico, on Butte County, Assessor’s Parcel Number 040-400-004.
