This book was released on 1979 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Choice of the appropriate tester for the evaluation of corn inbred lines is of major concern among corn breeders. Hence, comparisons among different testers are needed to determine their effectiveness in selecting inbred lines and in population improvement programs. Also, it is to determine whether to test the lines of corn early or late during the inbreeding process. Knowledge of the relationships between the mean yield of the lines per se and their testcrosses also is important. My objectives were to: 1) determine if there were significant differnces among S1 testcrosses, among S8 testcrosses, and between S1 versus S8 testcrosses, 2) compare the genetic variation among the different sets of testcrosses, 3) determine the relationships of inbred line performance among the different types of testers, and 4) compare the relation of testcross performance to line per se performance. Highly significant differences among the S1 and among the S8 testcorsses were found for all the traits. No significant differences, however, were detected between the S1 versus the S8 testcrosses for most of the traits. Genetic variance among the different S1 line and S8 line testcrosses was as theoretically expected for the related testers. That is, greater testcross genetic variance with the low yielding tester than the high yielding tester at both the S1 and S8 levels. S1 line testcrosses made with an unrelated high yielding tester, however, had the greatest genetic variance. Use of an unrelated high yielding inbred line was, (...).

Book excerpt: Research data is expensive and precious, yet it is seldom fully utilized due to our ability of comprehension. Graphical display is desirable, if not absolutely necessary, for fully understanding large data sets with complex interconnectedness and interactions. The newly developed GGE biplot methodology is a superior approach to the graphical analys

This book was released on 1976 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: To decide upon the most efficient breeding and testing procedures to improve maize populations, the plant breeder must have adequate knowledge of the type of gene action involved in yield heterosis. Two types of gene action have been postulated to account for yield heterosis in maize: dominance and overdominance. Recurrent selection of specific combining ability and for general combining ability have been proposed as methods to improve maize populations. Recurrent selection for specific combining ability uses a narow genetic base tester and originally was proposed on the assumption that overdominance is the main type of gene action responsible for yield heterosis. Conversely, selection for general combining ability uses a broad genetic base tester and assumes that dominant, favorable factors are concerned in yield heterosis. A procedure was proposed to compare the relative importance of dominance and overdominance in yield heterosis. This procedure involved recurrent relection for specific combining ability in two heterozygous source populations with a common inbred line tester. The purpose of this study was to evaluate progress in 5 cycles of recurrent slection for specific combining ability in two open-pollinated maize varieties and to determine the type of gene action involved in yield heterosis. The two source populations were the open-pollinated varieties, Kolkmeier and Lancaster, and the inbred line, Hy, was used as the common tester. After 5 cycles of recurrent selection, 6 population (C0 to C5) from (...).
