Conteúdo: |
Broad sense heritabilities and estimates of the number of factors or genes involved in the productjon of phytoene, -carotene, -carotene, a-carotene, Iycopene and total carotenoids were estimated in two different crosses of carrot (Daucus carota L.) with different backgrounds. F2 plants segregating for absence of a-carotene were identified in the cross B493 x QAL. HPLC chromatograms revealed that most of the increase of total carotenoids in high intensity mass selection (HCM), cycle 13, was due to jncrease of a-carotene content than {3-carotene. Broad sense heritabilities values were around or greater than 50% for {3- carotene, -carotene, Iycopene, phytoene and total carotenoid and around 35% for a- carotene in the cross Brasilia x HCM. In the cross orange x white the heritabifities were around or greater than 90%. The estimated number of factors was 4 for a-carotene, 3 for f3- carotene and total carotenes and one for -carotene, Iycopene and phytoene in the orange x dark orange cross, and 4 for a-carotene, 1-2 for Iycopene and total carotenes and 1 for the other carotenes in the orange x white cross. |
