  • a QTL that remain significant after the effects of proportion of fertile pollen are removed prior to analysis (see text).

  • Seed Δ% describes the percentage phenotypic difference in seeds per fruit from the LE parent. Where applicable, the QTL for total pollen count per flower (PN) or proportion of fertile pollen (PF) that is colocated with each seed QTL is identified. Pollen Δ% describes the percentage phenotypic change from the LE parent for the corresponding pollen trait at the same chromosomal region.
