Very-long-chain fatty acids (VLCFAs) have high application value in the fields of industry, medicine and food. Previous research has proved that total content of VLCFAs in the Arachis species is significantly higher than that in cultivated peanuts. In this study, contents of VLCFAs were determined in RIL population derived from the cross between Zhonghua 5 and ICGV86699 with wild species consanguinity. Board phenotypic variations of total very-long-chain fatty acid content ranging from 4.99% to 10.33% was observed among the RILs. Five lines with high total very-long-chain fatty acid content were identified, of them, the highest content of ZJ011 is 9.82%. Based on the previously constructed genetic map, 20 QTLs with 3.72%-15.66% phenotypic variation explained (PVE) were repeatedly detected, and were mainly located on chromosomes A04, B04 and B06. The results lay a molecular and material foundation for the improvement of oil quality. [ABSTRACT FROM AUTHOR] |
