Study on Yield Related Traits in Wheat

Book Description
Need for the improvement in wheat yield is increasing continuously due to day by day increase in human population on the same land. This challenge is much greater in the developing countries than the developed world. Many breeding programs are based on selection of desirable parents for hybridization that's the main source to create genetic variation which is heritable to offspring. This study was carried out to have information on the magnitude of heritability and genetic advance of various important wheat parameters as it plays an important role for planning breeding strategy. For this purpose second filial (F2) generation of ten cross combinations involving seven wheat varieties/genotypes were studied. These were planted in field in a Randomized Complete Block Design with three replications. At maturity 200 plants from each cross and 20 plants from each parent were taken and data were recorded. The information derived will be very helpful to make improvement in wheat yield through reliable selection as it is suggested that varieties/genotypes showing good results should be given due importance in future breeding programs.

Book Description
While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.
Wheat Landraces

Pages : 268
Book Description
Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.
Statistical Procedures for Agricultural Research

Category : Technology & Engineering
Languages : en
Pages : 698
Book Description
Here in one easy-to-understand volume are the statistical procedures and techniques the agricultural researcher needs to know in order to design, implement, analyze, and interpret the results of most experiments with crops. Designed specifically for the non-statistician, this valuable guide focuses on the practical problems of the field researcher. Throughout, it emphasizes the use of statistics as a tool of research—one that will help pinpoint research problems and select remedial measures. Whenever possible, mathematical formulations and statistical jargon are avoided. Originally published by the International Rice Research Institute, this widely respected guide has been totally updated and much expanded in this Second Edition. It now features new chapters on the analysis of multi-observation data and experiments conducted over time and space. Also included is a chapter on experiments in farmers' fields, a subject of major concern in developing countries where agricultural research is commonly conducted outside experiment stations. Statistical Procedures for Agricultural Research, Second Edition will prove equally useful to students and professional researchers in all agricultural and biological disciplines. A wealth of examples of actual experiments help readers to choose the statistical method best suited for their needs, and enable even the most complicated procedures to be easily understood and directly applied.

Identification of Genes/Genomic Regions Controlling Resistance to Biotic and Abiotic Stresses in Synthetic Hexaploid Wheat

Book Description
Synthetic hexaploid wheat (SHW; 2n=6x=42, AABBDD, Triticum aestivum L.) is produced from an interspecific cross between durum wheat (2n=4x=28, AABB, T. turgidum L.) and goat grass (2n=2x=14, DD, Aegilops tauschii Coss.). It is reported to have a considerable amount of genetic diversity and is a potential source of novel alleles controlling abiotic and biotic stresses resistance and improving wheat quality. Therefore, the first study was to understand the genetic diversity and population structure of SHWs and compare the genetic diversity of SHWs with elite bread wheat (BW) cultivars. The result of this study identified a wide range of genetic diversity within the SHWs. The genetic diversity of the ABD and D-genome of SHWs were 50% and 88.2%, respectively, higher than that found on the respective genome in a sample of elite BW cultivars. The second study was to identify novel genomic regions and underlying genes associated with grain yield and yield-related traits under two drought-stressed environments. This study identified 90 novel genomic regions and haplotype blocks associated with improving grain yield and yield-related traits with phenotypic variance explained of up to 32.3%. The third study was to identify common bunt resistance genotypes, genomic regions and underlying genes conferring resistance to common bunt. This study identified 29 resistant SHWs and 15 genomic regions (five were novel) conferring resistance to common bunt. The fourth study to explore the genetic variation of 10-grain minerals (Ca, Cd, Co, Cu, Fe, Li, Mg, Mn, Ni, and Zn) and grain protein concentration (GPC); identify marker-trait associations and candidate genes associated with grain minerals using a genome-wide association study (GWAS). A wide range of genetic variation identified within SHWs for GPC and grain mineral concentrations. A GWAS identified 92 genomic regions (60 were novel and 40 were within genes) associated with increasing beneficial grain mineral concentration and decreasing concentration of toxic compound such as Cd. The results from this research will be valuable for broadening the genetic base of wheat and could assist in further understanding of the genetic architecture of traits under biotic and abiotic stresses.
