Abstract
52 females F2 derivatives from the cross between approximately diploid apomictic and diploid sexual Parthenium argentatum were hybridized with P. stramonium. Fertilization was the rule as only interspecific hybrids and no maternals were obtained among the 52 progeny families. Among 39 families which could be analyzed no evidence for nonreduction in the mother plants was found. Statistically it appears probable that apomixis in guayule is based on at least 4 recessive genes: a minimum of 2 controlling the occurrence of reduction and 2 more the requirement for fertilization. There may be some doubt, however, whether on the diploid level these 2 components of apomixis are independent as they are in polyploid amomicts.This publication has 1 reference indexed in Scilit:
