Book excerpt: The properties of continuous variation are basic to the theory of evolution and to the practice of plant and animal improvement. Yet the genetical study of continuous variation has lagged far behind that of discontinuous variation. The reason for this situation is basically methodological. Mendel gave us not merely his principles of heredity, but also a method of experiment by which these principles could be tested over a wider range of living species, and extended into the elaborate genetical theory of today. The power of this tool is well attested by the speed with which genetics has grown. In less than fifty years, it has not only developed a theoretical structure which is unique in the biological sciences, but has established a union with nuclear cytology so close that the two have become virtually a single science offering us a new approach to problems so diverse as those of evolution, development, disease, cellular chemistry and human welfare. Much of this progress would have been impossible and all would have been slower without the Mendelian method of recognizing and using unit differences in the genetic materials.

This book was released on 2012-04 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experiment was carried out with genetic divergence of spring wheat and combining ability, heterosis and heritability for yield and yield contributing characters from a five parent- half diallel cross in F2 generation for genotypes of wheat. Genetic divergence was assessed through Mahalanobis' D2 -statistics and Principal Component Analysis (PCA). The genotypes were grouped into six clusters. The combining ability analysis studied in the diallel cross populations. General combining ability (GCA) and specific combining ability (SCA) mean squares in F2 generation was significant for all the characters. There was significant expression of non additive gene actions even in F2 generation, which indicates that epistatic components of non additive gene actions might have been involved. The crosses Sonora x Opata and SA-92 x Rawal had positive and significant SCA effects for grain yield. Maximum mid parent heterosis for grain yield was 39.97% in the cross Sonora x NK-5 which was much higher than mid parent heterosis for other yield contributing characters. Positive relation was observed between heterosis of the crosses with their corresponding SCA effects.

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of Biometricai Genetics, which appeared in 1971, we set out to give a general account of the subject as it had developed up to that time. Such an account necessarily had to be comprehensive and reasonably detailed. Although it could be, and indeed has been, used by those who were making an acquaintance with this branch of genetics for the first time, it went beyond their needs. We have been encouraged therefore to write an introduction to the genetical analysis of continuous variation aimed primarily at senior undergraduate and postgraduate students, and concentrating on basic considerations, basic principles and basic techniques. This has meant, of course, omitting all reference to some phenomena of more restricted interest, notably sex-linkage, ma ternal effects, haploidy and polyploidy. It has meant, too, that even with some phenomena which have been included, like interactions, linkage and effective factors, the discussions cannot go into full detail. Anyone who is interested, however, can find further information in Biometricai Genetics, to which detailed references have been given where it ap peared that these would be helpful. The order of presentation has been changed with the aim of making it easier for beginners.

Available in PDF, EPUB and Kindle. Book excerpt: Wheat is an important cereal crop throughout the world and also in Pakistan. A lot of research work is going on to develop high yielding wheat varieties.Line×tester analysis is one of efficient breeding strategies to evaluate combining ability effects of genotypes and also to provide information regarding genetic mechanisms controlling yield and yield related traits.Combining ability analysis would be of great help to identify the most suitable and desirable parental material to breed further to get the hybrids which have the desirable characters for the breeders.The line x tester cross experiment in spring wheat (Triticum aestivum L.) was used to estimate the combining ability effects involved in the control and expression of some polygenic traits of economic importance.This book provide information regarding wheat and its yield related traits to improve the yield.
