This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Synopsis An evaluation of parents of grain sorghum hybrids by : J. G. King
Download or read book An evaluation of parents of grain sorghum hybrids written by J. G. King and published by . This book was released on 1961 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents summarized data on origins, characteristics and performance of parental lines of sorghum hybrids. This information has been derived from the long-time cooperative sorghum improvement research of the Texas Agricultural Experiment Station and the Crops Research Division of the United States Department of Agriculture. The information will be especially useful to geneticists, breeders and producers of seed of sorghum hybrids. All the seed parents produce high-yielding hybrids with the male parents of highest combining value. A few high-yielding hybrids result from crossing parents neither of which has high combining value. Many of the male parents tested do not produce high-yielding hybrids with the female parents available.

This book was released on 1970 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectivinese of early generation testing for combinig ability for grain yield in grain sorghum restorer lines was studied at College Station, Texas, Two well-Known restorer lines, TX 7078 and TX 09, were crossed and resulting F@, F$, and F^ segregates were evaluated for combining ability. In the F2 population, 70 F2 plants were crossed to each of four male-sterile lines, A Tx 3197 (Combine Kafir-60), A Tx 398 (Martin), A Tx 378 (Redlan), and A Tx 3048 (Redbine sel.). These "F2 hybrids" were grown in a replicated test in 1962. Based on the mean yield of the four hybrids with each F2, 12 high- and 12 low-combining F2's were selected for advancement to the F4 generation. The F4 lines from each of these 24 selected F2's were crossed to each of the same four male-steriles and the hybrids tested in 195=63. Three high-and three low-combining F2 families were closen for further study in the F6. The F6 lines were crossed of the same four male-steriles and the hybrids tested in 1964. By compring, within families, the yield of "F2 hybrids" with the yield of "F4 hybrids" and "F6 hybrids, the effectiveb=ness of early generation testing for combining ability was estimated. High-combining F2's produced F4 lines and F6 lines that were significantly higher in combining ability than the F4 and F6 lines derived from low-combining F2's. Correlation coefficients for yield between "F2 hybrids" and "F4 hybrids', F2 hybrids" and "F6 hybrids"' and "F4 hybrids" and F6 hybrids" were generally large, positive, and significant (...).

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum [Sorghum bicolor (L.) Moench] production in Africa is widespread with low yields due to low inputs and the lack of sorghum hybrids. This situation has forced most of these farmers to grow maize hybrids since they are readily available in the seed market. Sorghum hybrids could be used if their potential was demonstrated. The objective of this study is to document the level of heterosis in Southern Africa sorghum germplasm. The performance of 52 F1 grain sorghum hybrids and their parental lines was evaluated in four environments. Measurements for grain yield, panicle exsertion, days to mid anthesis and plant height were analyzed to obtain estimates of high parent heterosis. High parent heterosis was observed to be 37.18% for yield, 82.77% for exsertion, 0.02% for days to mid anthesis and 23.7% for height. ICSR-939 and (87EON366*90EON328)-LD30 can be used as testers to develop more female lines for further hybrid seed production in breeding programs because they had the highest general combining ability. Protein content averaged 11.69%. ATx635 had significantly higher protein content than ATx631 (13.49% compared to 9.69%, respectively) and its hybrids had more protein than ATx631 hybrids (11.6% compared to 10.67% for ATx631). Mean heterosis for protein content was negative at -12.5%. This shows that hybrids had lower protein content than their parents since protein content is negatively correlated to grain yield ( -0.35**). Starch content averaged 72.13% and ATx631 hybrids had more starch than ATx635 hybrids (73.16 compared to 72.37% respectively). Two hybrids, ATx. 631/(87EON366*90EON328)-LD30 and ATx631/ ((TAM428*SV1)*CE151)-LD3 had the highest yields (5.04 t/ha and 4.93 t/ha, respectively). These hybrids also had small grains with good hardness and acceptable whiteness. They had good exsertion, flowered in good time and had acceptable plant heights. These two hybrids were compared to regional check varieties Macia and Tegemeo for all traits and they were either superior or within an acceptable range. These two hybrids are therefore recommended for release in the region. There is need therefore to start working on the various components of seed systems in the region so that seed of these two hybrids is made available to farmers who need the seed.
