Histological analysis of anthesis ovary and fully grown fruit of fs8.1 NILs

For each genotype, six ovaries and 18 fruits from six plants were investigated. The two values per organ represent two biological replicates. The upper value was obtained from family 13S140, and lower value was obtained from the 13S117/118 families. NA, not analysed; NS, not significant.
