<p align="center"><strong>ABSTRACT</strong></p><p align="center"><strong> </strong></p>Sorghum is one of the potential foods with a higher protein content than rice. Sorghum seeds can be milled and cooked as sorghum rice. This study was aimed to obtain information on the inheritance of morphological and agronomic characters from the population derived from crosses of wide genetic background. The study consisted of the formation of F1 population and evaluation of morphological and agronomic characters in the segregated population (F2) of the three selected F1 genotypes. The location of the research was at IPB Experimental Field, Leuwikopo. The performance of the F1 genotypes were between the two parents, except for the yield components of PI-150-20-A x Numbu and PI-150-20-A x Kawali were higher than the parental lines. The performance of the F2 generation population was also between the parental lines, but with a wider distribution. The sorghum seed color is controlled not only by additive and dominant gene action, but also by epistatic gene action. The character of seed weight per panicle is controlled by epistatic gene action. In the F2 population of the crosses of PI-150-20-A x Numbu and PI-150-20-A x Kawali and PI-10-90-A x Numbu, the seed weight character is inherited with moderate heritability value. Based on genes action dan heritability, bulk or single seed descent method are suitable for yield improvement of the populations.<br /><br />Keywords: gene action, heritability, seed color, segregation, sorghum<br /><br /><br />

Soybean breeding and selection is a continual process designed to increase yield levels and improve resistance to biotic and abiotic stresses. Soybean breeders have been successful in producing a large number of varieties using conventional breeding methods, the Single Seed Descent method in particular. In recent decades, with the increased use of genetic transformations, backcrossing is more frequent though the only trait that has been commercialized is glyphosate tolerance. Physiological breeding poses a particular challenge, as well as phenotyping and development of useful criteria and techniques suitable for plant breeding. Using modern remote sensing techniques provides great opportunity for collecting a large amount of physiological data in real environment, which is necessary for physiological breeding. Molecular based plant breeding methods and techniques are a conceptual part of any serious breeding program. Among those methods, the most extensively used is marker-assisted selection, as a supplement to conventional breeding methods.
