Abstract

New and better adapted varieties of crop plants have resulted from the application of the principles of genetics. Fundamental research in the field of barley genetics has helped the plant breeder in developing better varieties for specific uses and adaptability.

Barley is one of the best cultivated crop plants for making genetic studies. It has a wide range of adaptability, exhibits a host of contrasting genetic characters, is a simple diploid with only seven pairs of chromosomes, and all the cultivated species are inter-fertile.

The mode of inheritance of nearly 200 characters has been studied, many of whose genes have been mapped and assigned to one of the seven chromosomes.

The inheritance and linkage of the factors responsible for anthocyanin pigmentation in the auricle of barley is the primary purpose of this study.

Other character pairs are included in this study for possible linkages with purple auricle or with each other. These linkages may help materially in mapping genes on their respective chromosome.

A new system of designating the linkage groups and chromosomes with Arabic numbers, adopted by the Fourth Annual Barley Research Worker's Conference, will be followed throughout this study. Comparison of the new and old systems is given in table 1.
