Heterosis and Inbreeding Depression in Two Soybean Single Crosses
Heterosis is considered to be of little importance in soybean (Glycine max L. Merr.) because the crop is produced as “pure-line” cultivars or blends of inbred lines. The F1 generations Holladay/ Hutcheson (Cross 1) and Brim/Boggs (Cross 2) were generated by hand pollinations. Inbred generations were generated by bulk selfing. The F1, F2, F3, F4, and F5 generations were yield-tested in replicate...
متن کاملAccelerating yield potential in soybean: potential targets for biotechnological improvement.
Soybean (Glycine max Merr.) is the world's most widely grown legume and provides an important source of protein and oil. Global soybean production and yield per hectare increased steadily over the past century with improved agronomy and development of cultivars suited to a wide range of latitudes. In order to meet the needs of a growing world population without unsustainable expansion of the la...
متن کاملAnalysis of the Physicochemical Properties and Grain Yield of Some Rice Promising Lines From Multiple Crosses
Grain quality currently represents a major problem in high yielding rice production in Iran and many other rice producing areas of the world. Quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. These research genetic materials we...

متن کاملInbreeding in populations with overlapping generations.
An inbreeding matrix is defined for populations with overlapping generations. In the short term it can be expressed in terms of a matrix specifying the passage of genes between the different age groups (and sexes) and a diagonal matrix whose elements depend on the number of individuals in each age group. Formulae for the inbreeding effective number are derived using matrix theory. A comparison ...
