Abstract The inheritances of thousand kernel weight (TKW), protein percentage, protein quality and grain hardness were studied through an 11 x 11 complete diallel set of bread wheat genotypes consisting of four alloplasmic lines of Selkirk, two alloplasmic lines of Siete Cerros 66, and five commercial cultivars. Genetic components accounted for 93%, 90%, 78%, and 92% of total variation for TKW, protein percentage, protein quality, and grain hardness, respectively. General combining ability (GCA) effects were dominant for TKW (48% GCA, 38% SCA [specific combining ability], and 7% reciprocal effects [RE]), protein percentage (70% GCA, 10% SCA, and 10% RE), and grain hardness (59% GCA, 29% SCA, and 4% RE). However, SCA effects dominated for protein quality (30% GCA, 43% SCA, and 5% RE). Broad- and narrow-sense heritabilities were estimated at 0.95 and 0.65 for TKW, 0.94 and 0.82 for protein percentage, 0.83 and 0.47 for protein quality, and 0.95 and 0.74 for grain hardness. Reciprocal effects were highly significant for all quality traits, but less effective than additive and non-additive gene effects. Aegilops cylindrica, Ae. ventricosa, and Triticum turgidum cytoplasms showed positive effects on TKW in some crosses. Ae. cylindrica, Ae. variabilis, and Ae. uniaristata cytoplasms seemed to have potential for improving protein percentage. T. aestivum cytoplasms were superior to alien cytoplasms for protein quality. Bolal 2973, Kiraç 66 and Bezostaja 1 cytoplasms increased protein quality in some crosses. Ae. cylindrica, Ae. variabilis, Ae. ventricosa and Ae. uniaristata cytoplasms had significant effects on grain hardness. The cytoplasmic variation in B type T. aestivum cytoplasm was found to be significant for all traits.

Abstract As the only institution of higher education in Kuwait offering a four-year degree program, Kuwait University is expected to provide its society and its rapidly changing labor market with professionally trained Kuwaiti nationals in fields requiring up-to-date scientific and technical knowledge. Its location in the Arabian Gulf region requires KU to honor and preserve the Arab and Islamic tradition. Thus, the success of KU graduates in the job market and in society will depend on a combination of scientific knowledge and appreciation for local and regional values. With the introduction of the graduate studies program, KU is on the threshold of becoming a major institution of research and scholarship. With this step forward, KU increases its responsibility to offer a diversified academic program designed to meet the specialized manpower requirements of Kuwait as a major commercial center in the Middle East. To evaluate its programs, KU established the Center for Evaluation and Measurement in 1977 which introduced the Course and Instructor Evaluation project, and later expanded its activities through the KU Academic Evaluation Committee, to include program evaluation. The office of the Vice-Rector for Research was established in 1981 to encourage, support, and develop scientific research activities at Kuwait University. At present, KU has fully realized the importance of educational reform. A few of the issues, identified in this paper, can be outlined as follows: 1. The need for an admission policy to recruit more students competent in general subject matter knowledge as well as in English proficiency, and to assign them fairly to the subject areas of choice. 2. The need to design a research oriented curriculum with stronger emphasis on general education as required of an undergraduate studies program rather than stressing professionalism. 3. The need for an instructional program that deemphasizes students' total reliance on memorization and examinations for completing course requirements. 4. The need to improve instructional and research facilities, as well as make them available to students and to train students in their proper use. 5. The need to reappraise employment conditions for non-Kuwaiti teaching staff providing them with job security and career certainty. 6. The need for an administratively and financially independent KU, and long-range plan for a campus to accommodate the increasing number of students, faculty, and support staff. fa]This report is based on studies conducted at the Center for Evaluation and Measurement and on the status reports of several foreign consultants, members of the KUAE Committee, who evaluated various departments. The author has highlighted those issues and added his interpretations in various areas of the academic program dealing with admission and recruitment of students and their career preparation, as well as curriculum, instruction, faculty, research, facilities, and introduction of graduate studies at Kuwait University.
