Development of lemongrass clones with high oil content through population improvement
1992
Kulkarni, R.N. | Ramesh, S.
Fourteen clones with high oil content were developed from cycle-1 (C1) population of a phenotypic recurrent selection program for high oil content in East Indian lemongrass (Cymbopogon flexuosus). These clones were evaluated in a one-year trial along with two checks, (i) a local variety, OD 19, and (ii) the best clone from the base population, 52-22. The mean oil contents of these clones ranged from 0.91 to 1.4% as against 0.53% of local cultivar, OD 19. The top two clones, R8P6 and R16P3, which were developed from a low citral variant isolated from C1 population, had about 150 to 50% higher oil content than OD 19 and 52-22, respectively. Although the leaf yields and dry matter contents of these two clones were on par with those of the checks, their citral contents were significantly lower, particularly during the second harvest when the temperatures were relatively higher than those during the first or third harvests. However, the citral content of clones PC5 and PC8, which ranked next to R8P6 and R16P3 for oil content, was not affected by temperature variations during three harvests and was almost on par with those of the checks, as were their leaf yields and dry matter contents.
