Same segregating progenies from F6 lines were tested for each trial; Bostwick values were presented as mean ± sd. Field trials for year 1 and year 2, site 1 were conducted at Heinz's research farm (Stockton, CA) and for year 2, site 2 at Huron, CA. P values were based on one-tailed distribution of two samples with unequal variance using Student's t test. *n, Number of independent segregates evaluated for each genotype in every trial. Among 70274 progenies tested, one had vis1-lta genotype.
