| Abstract | Sesame breeding to increase oil content and maintain acceptable agronomic traits is important to Thailand's agriculture. The objectives of this study were to evaluate segregation, broad sense heritability and phenotypic correlation on agronomic traits and oilcontent in F2 population of KKU 1 x C-plus 2 and Mahasarakham 60 x Kanchanaburi.This study was carried out at Faculty of Agricultural Technology, Kalasin University.The agronomic traits of individual plant selected were recorded and oil content was analyzed.The results showed that F2 population of both crosses demonstrated continuous segregationfor agronomic traits and oil content. The genetics of parent used affected the oil contentdistribution of F2 population. The F2 population that came from crossing between high oilcontent cultivars tend to have higher number of individual plants with high oil content thanthose coming from crossing between low oil content cultivars. The twenty-five breedinglines of KKU 1 x C-plus 2 and the twenty-seven breeding lines of Mahasarakham60 x Kanchanaburi were chosen by their good agronomic traits and high oil content forcontinued selection in F3 population. Heritability of agronomic traits and yield were low whileheritability of oil content was moderate to relatively high. Significant positive correlationcoefficients were found between oil content with branch/plant, length of capsule andyield/plant in KKU1 x C-plus 2. In contrast, correlation between oil content and agronomictraits for Mahasarakham 60 x Kanchanaburi in F2 population was not found. |
