During the process of creating the 2007 version of the Rules, errors occurred due to a software conversion issue. The files were created in the Microsoft Word 2000 version and converted using the Microsoft Word 2007 version. It was expected that it would be a seamless transfer, but Word 2007 replaced division symbols with “)”. This created formula errors on five pages of the rules (2-6, 2-25, 3-3, 3-4, and 3-7). Unfortunately this was not discovered until the 2007 Rules CD had been distributed. These errors have been corrected and a new CD of the Rules will be mailed to everyone that received a CD, or printed replacement pages for those who purchased a print version.
Corrected Rules pages: For the Uniform Classification Handbook of Weed & Crop Seed (Handbook #25) grammatical corrections were made to pages 18 (Bothriochloa laguroides subsp. Torreyana), 48 (Festuca ovina), 98 (Salvinia molesta – Salviniaceae), and AD-81(Salvinia molesta – Salviniaceae).
Corrected Handbook 25
pages: We apologize for this error and will strive to ensure that errors do not occur in future issues.
New crop cultivars are continually developed and released. In addition, the methods for development of new cultivars are changing. Recent advances in biotechnology (molecular genetics) promise to add significant diversity to current crop germplasm. These advancements have led to an increasing dilemma for breeders, the seed industry, certification agencies, and seed enforcement individuals in their attempt(s) to assure maintenance of genetic integrity for these improved agricultural products. Traditional approaches utilizing plant morphological traits have proven limiting and often fail to provide the speed of identification essential for the movement of seed in commerce. As a result, there is a greater need to explore alternative methods to characterize crop cultivars. This AOSA Cultivar Purity Testing Handbook is, in part, a response to that request. This Handbook collates cultivar purity information from various sources into one common reference. As with any Handbook, continuing research, development, and refinements in testing techniques are expected to culminate in new test methodologies and present test revisions. To accommodate these modifications, this Handbook has been prepared in loose-leaf format so that new sections can be added when appropriate. Color photographs are presented to depict differences among cultivars. Color slides of these same traits are also available from the AOSA Secretary.
AOSA Announces a new
and comprehensive Seed Moisture Testing Handbook!
This innovative handbook provides
standardized procedures for testing moisture and enhances
the value of the AOSA Rules for Testing Seeds. Seed
moisture content is an important aspect of seed quality.
It influences production decisions related to harvest,
conditioning, and storage. Knowledge of seed moisture
content prior to treatment is essential for optimum seed
enhancement protocols such as priming, pelleting,
coatings, etc. Seed moisture must be monitored during
storage to minimize microorganism development, maintain
seed quality, and assist inventory management. Seed
moisture also influences germination with respect to
imbibitional damage, speed of germination and seedling
development.
Seed testing has been developed to aid agriculture in avoiding some of the hazards of crop production by furnishing needed information about seeds that are to be used for planting purposes. This information may be desired for the seed producer or seed dealer in connection with seed conditioning or merchandising; as a guide to the person who will plant the seed; or for seed control purposes. In all these cases the ultimate purpose of making the test is to determine the value of the seed for planting. There has been developed, especially in connection with the enforcement of labeling laws, a standard analysis that furnishes information as to the composition of the seed sample and of the ability of the seed to produce plants. It is desirable to have definitions and fundamental procedures agreed upon that are based on a thorough knowledge of the principles involved. The following rules attempt to summarize and make useful the accumulated experience of seed analysts, and are to be followed as a matter of routine. When samples appear to require special treatment resulting in deviations from the rules, a statement of the method used should be made on the laboratory report. This document constitutes the official AOSA statement regarding seed testing procedures.
