Abstract:
A method of producing seed for commercial production of a desired cucurbit hybrid plant variety, comprising the steps of:identifying a first cucurbit plant line with a suitable male-sterile gene;identifying a second cucurbit plant line with a suitable marker gene, said marker gene being disposed with respect to said male-sterile gene in one of the following two relative dispositions, the first of said relative dispositions being on separate chromosomes and the second of said relative dispositions being on the same pair of chromosomes such that said male-sterile gene and said marker gene independently segregate;crossing sufficient generations of progeny of said two lines to produce a genetic stock which is double recessive for said male-sterile and marker genes;crossing said double recessive as a female parent with a suitable male parent; andharvesting hybrid seed from the female parent.
