Heteroallelic combinations of hopmsvland some other hop alleles result in viable adult females with various phenotypes. The severity of these heteroallelic phenotypes can be enhanced by introduction of the updYM55allele on the hopmsvlchromosome. Viability was scored relative to the hop/FM7 females from the same cross. The held-down wing phenotype was scored as present or absent from females. Egg production is indicated as follows: (−) for complete lack of any eggs deposited; (+) for production of small numbers of eggs, and (+++) for production of nearly normal numbers of eggs. Phenotypes that are not applicable are denoted N.A.
