Table 7 QTL for spring yield (SY) and cumulative summer biomass (CSB) identified in a pseudo-testcross F1 (3010 x CW 1010) population. The SY phenotypic data was collected for two years and CSB phenotypic data was collected for one year

From: QTL mapping of flowering time and biomass yield in tetraploid alfalfa (Medicago sativa L.)

  1. JPC and BVL refer to the two locations - the J. Phil Campbell Sr. Research and Education Center (JPC) in Watkinsville and the Georgia Mountain Research and Education Center (BVL) in Blairsville, respectively
  2. The negative allele direction (−) refers to the low biomass or the QTL responsible for reduced biomass yield, and the positive allele direction (+) refers to the QTL responsible for the higher biomass. The peak and flanking markers given are based on the 1- LOD support interval (LSI)
