Abstract:

Phenylpropenes play an important role in plant defense against animals and microorganisms, and in attracting pollinators and insects. We report the genetic inheritance of methyl chavicol and eugenol following a cross between the sweet basil varieties ‘Perrie’ and ‘Cardinal,’ eugenol and methyl chavicol chemotypes, respectively. Methyl chavicol was detected only in ‘Cardinal,’ accounting for more than 95% of the total phenylpropenes. Eugenol was most abundant in ‘Perrie,’ accounting for more than 99% of the total phenylpropenes. Eugenol, chavicol and methyl chavicol were detected in F1 hybrids at intermediate levels (10%–52%) without statistical differences (> .05) for any compound among the F1 progeny arising from the different crossed pairs. The F2 progeny segregated into three groups, 23%–25% to a eugenol chemotype, 23%–25% to a methyl chavicol chemotype, and the remaining (~50%) into an intermediate mixture of the two compounds. This distribution fitted a segregation ratio of 1:2:1 (χ2 = 1.71; = .4249), suggesting that the phenylpropene phenotype is regulated by a single bi‐allelic gene with incomplete dominance. A putative association with biosynthesis enzymes is discussed.

Heredity of phenylpropenes in sweet basil (Ocimum basilicum L.) chemotypes and their distribution within an F2 population

Phenylpropenes play an important role in plant defense against animals and microorganisms, and in attracting pollinators and insects. We report the genetic inheritance of methyl chavicol and eugenol following a cross between the sweet basil varieties ‘Perrie’ and ‘Cardinal,’ eugenol and methyl chavicol chemotypes, respectively. Methyl chavicol was detected only in ‘Cardinal,’ accounting for more than 95% of the total phenylpropenes. Eugenol was most abundant in ‘Perrie,’ accounting for more than 99% of the total phenylpropenes. Eugenol, chavicol and methyl chavicol were detected in F1 hybrids at intermediate levels (10%–52%) without statistical differences (> .05) for any compound among the F1 progeny arising from the different crossed pairs. The F2 progeny segregated into three groups, 23%–25% to a eugenol chemotype, 23%–25% to a methyl chavicol chemotype, and the remaining (~50%) into an intermediate mixture of the two compounds. This distribution fitted a segregation ratio of 1:2:1 (χ2 = 1.71; = .4249), suggesting that the phenylpropene phenotype is regulated by a single bi‐allelic gene with incomplete dominance. A putative association with biosynthesis enzymes is discussed.
