Seed Δ% describes the percentage of phenotypic difference in seeds per fruit from the SL parent. Where applicable, the QTL for total pollen count per flower (PN) or the proportion of fertile pollen (PF) that is colocated with or adjacent to each seed QTL is named. Pollen Δ% describes the percentage of phenotypic change from the SL parent for the corresponding pollen trait at the same chromosomal region.
a
Pollen-associated seed QTL that remain significant after the effects of the proportion of fertile pollen are removed prior to analysis (see text).
