Selection Methodology

The results of recently completed genetic studies indicate that the green cotyledon trait exhibited by the southernpea [Vigna unguiculata (L.) Walp.] cultivar Bettergreen is conditioned by a single recessive gene. This gene, designated green cotyledon and symbolized gc, is neither allelic to nor linked with the gt gene that conditions the green testa trait exhibited by the cultivar Freezegreen. The color of seeds harvested from plants homozygous for both the gc and gt genes is superior and more uniform than the color of seeds harvested from either Better-green or Freezegreen plants. This observation suggests that efforts should be initiated to study the feasibility of using both the gc and gt genes to develop cultivars that produce seed with an enhanced, persistent green color. The selection methodology for both seed traits is rapid and reliable. The green cotyledon trait can be selected in the seed stage.

Cooking Conditions

Cooking times of fourteen Egyptian and introduced cowpea genotypes were evaluated under different cooking conditions. Soaking treatments manifested shorter time than unsoaked treatments. Adding sodium bicarbonate or baking powder to soaking and cooking solutions gave more shorter cooking time. Microwaves treatment gave the shortest cooking time than all other treatments and conserved as a new approach. All studied cowpea genotypes and all cooking treatments exhibited significant variations. The blacked colored seeds needed shorter cooking time than the red seeds, while round or small seeds needed longer time to complete cooking. The observed significant differences among the genotypes were reflected to genotypic and phenotypic variations and consequently to high broad sense heritability estimates and to high values of genetic advances. Such estimates suggested the ability to achieve possible improvement in cooking time of cowpea seeds which might eventually reflect on their cooking quality.

Cowpea Varieties

Cowpea (Vigna unguiculata) is a legume that is cultivated throughout Africa and contributes a significant amount of plant-based protein to human diets. There are many varieties of cowpeas, and these have varying seed characteristics such as shape, size, colour and nutritional properties. The compositional, physico-mechanical, and functional properties of two new cowpea seed varieties were investigated in order to determine their full food-use potentials as well as key parameters for their postharvest machinery for processing, handling, and storage. The proximate composition of the two cowpea cultivars was determined using standard methods. Physico-mechanical analyses carried out were the hundred-seed weight and volume, bulk density, true density, size, aspect ratio, surface area, equivalent diameter, porosity and angle of repose. Functional properties determined were cooking time and water uptake of the grain as well as water and oil absorption, foam capacity and stability, and emulsion capacity and stability of the flour. The Padi-Tuya variety was longer, broader and thicker than Wang Kae. The results showed both varieties to be useful sources of macronutrients. The moisture, fat and fibre in Wang Kae were significantly higher (p<0.05) than Padi-Tuya. However, both cowpea varieties had comparable protein levels of 17.7 g/100 g. The cooking time, hydration capacities and indices of the two varieties were also significantly different (p<0.05), but their swelling capacities, swelling and water uptake indices were comparable. Cooking times were 40 and 62 min for Padi-Tuya and Wang Kae, respectively. The water and oil absorption capacities, as well as the swelling indices, were similar, but their emulsion capacities and stabilities were significantly different (p<0.05) for the flour. Padi-Tuya had a higher foam capacity, but was less stable, than Wang Kae. The physico-mechanical properties determined would aid in the design of cleaning, handling and other processing machinery as well as storage facilities for the new cowpeas. The functional and the compositional parameters would assist in the food formulations.

Abstract. Summary: The term “LDL hypothesis” is frequently used to describe the association of low-density lipoprotein cholesterol (LDL-cholesterol, LDL-C) and cardiovascular (CV) events. Recent data from genetic studies prove a causal relation between serum LDL-C and CV events. These data are in agreement with mechanistic molecular studies and epidemiology. New randomised clinical trial data show that LDL-C lowering with statins and a non-statin drug, ezetimibe, reduces CV events. We therefore believe that the “LDL-hypothesis” has been proven; the term appears to be outdated and should be replaced by “LDL causality”.

Methods are described for deriving personal and family histories of birth, marriage, procreation, ill health and death, for large populations, from existing civil registrations of vital events and the routine records of ill health. Computers have been used to group together and »link« the separately derived records pertaining to successive events in the lives of the same individuals and families, rapidly and on a large scale. Most of the records employed are already available as machine readable punchcards and magnetic tapes, for statistical and administrative purposes, and only minor modifications have been made to the manner in which these are produced.As applied to the population of the Canadian province of British Columbia (currently about 2 million people) these methods have already yielded substantial information on the risks of disease: a) in the population, b) in relation to various parental characteristics, and c) as correlated with previous occurrences in the family histories.
