“…The paper test employed was similar to that previously described for unheated samples (6), except that a drop of [:I-glucosidase preparation was added to each sample spot as soon as an entire sheet of samples had been taken. This procedure insured the hydrolysis of cis-a·hydroxycinnamic acid glucoside in those samples lacking endogenous [:I-glucosidase activity, and thus permitted the accurate classification of Cuand cucu plants regardless of constitution with respect to the B/b alleles.…”

Contamination levels observed in the breeder, foundation, and certified seed generations of ‘Denta’ sweetclover (Melilotus alba Desr.) were 0.71, 1.69, and 3.62%, respectively, as measured by the frequency of plants high in content of ο‐hydroxycinnamic acid. Based on a sample of plants tested simultaneously for ο‐hydroxycinnamic acid content and β‐glucosidase activity, a small but consistent decrease in the frequency of cu plants occurred with succeeding seed generations, while shifts in the frequency of b plants were not consistent in magnitude or direction. Contamination through cross‐pollination with CuCuBB plants may be the major factor responsible for the observed decreases in the frequency of cu plants.

“…This procedure also was similar to that previously described for unheated samples (6), except that a drop of sweetclover leaf extract containing cis-o-hydroxycinnamic acid glucoside (approximately I mg/ml) was added to the sample spot. By this means, B-plants were readily distinguished from bb plants.…”

This paper outlines the concept of "programn and one set of elements that are considered to make up the program planning process in agricultural extension, and an example of practical program planning in Rhodesia is given. Although there is a wide variety of meanings attached to the term nprogramn in adult education, it has been stated by Thomas (1964) that all programs consist of two factors: (1) the relationship between participant and agent (usually oral); and (2) a variety of relationships with a variety of factors in the environment, all chosen and planned by these two parties. Four overlapping factors suggested by Verner (1964) as the basis for designing the learning experience, provide a simple model which could be elaborated to suit various situations and levels of planning:. (1) determination of needs; (2) identification of educational goals; (3) arrangement of learning tasks; and (4) measurement of achievement. Each of these steps is discussed. The cited program in Rhodesia, in the rather isolated Gokwe district, is based on cotton production. The foundation of the program is close liaison between specialists, extension staff, and the Cooperative Officer, and consists of the following essentials: a program that is technically sound and economically attractive; close cooperation of Extension and Cooperative functions; locally adapted recommendations, simplified to the essentials; emphasis on staff training (technical and team work); annual programs of main events; and monthly work program prepared one month in advance from the farmer/field worker level upwards.
