THE GENETIC CHARACTERIZATION OF WILD SUNFLOWER SPECIES (HELIANTHUS SPP.) AND INTERSPECIFIC HYBRIDS BASED ON BROOMRAPE RESISTANCE, 2021

It is mostly grown in the Central Anatolia Region as dried nuts as a snack and as bird feed for birds. It is a very popular agricultural plant in the Thrace Region, and since it is seen as an important oil plant in this region, it is mostly cultivated as oil. The sunflower was seen wild in nature in the 1000s BC and attracted attention due to its appearance. Over time, it has been improved by many sunflower growers and researchers to obtain the oil in its content and to benefit from its seeds and has taken its place as a very important commercial agricultural plant in the world. It is still being bred for many improvement studies and is the main subject of many molecular studies. The cultivated sunflower germplasm contains and preserves 50% of the genetic diversity found in its wild relatives. The strength of coupling quality requires the use of genetic diversity present in cultured hybrids and wild gene sources to develop pre-cultivation lines and material that provides the elite standard. Sunflower hybrid breeding includes the development of appropriate breeding lines for diseases, abiotic stress and herbicide resistance. These lines are created by crossing wild species with cultured sunflowers, crossing wild species with other wild species, or hybrid cultivating with other species as a result of crossbreeding. The biggest problem in cytoplasmic male infertility, diseases, abiotic and especially sunflower is Orobanche spp. wide crosses were made to find solutions to their resistance. These goals are fulfilled through repeated choices to improve the population. But choosing phenotypically durable lines is time consuming and not very reliable. Thanks to the molecular markers, durable breeds are detected in a short time and the time to obtain hybrid varieties is shortened and accurate, reliable results are obtained. Thus, a high increase in efficiency will be observed by providing a permanent endurance.
