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

BMC Plant Biology

Table 2 Least square (LS) means for F1 and the parents for the timing of flowering (TOF), the spring yield (SY) and the cumulative summer biomass (CSB)

Trait	Environment	F1^a	3010^b	CW 1010^b
TOF015	JPC	112–130	117	119
TOF017	JPC	85–110	101	102
TOF015	BVL	146–163	149	151
TOF017	BVL	118–136	118	121
SY017	JPC	0.33–1.9	0.64	1.05
CSB	JPC	0.11–1.48	0.347	0.34
SY018	JPC	0.10–1.35	0.83	0.86
SY017	BVL	0.25–2.05	1.08	0.7
CSB	BVL	0.05–0.75	0.37	0.25

The units for TOF, SY, and CSB are in Julian days, Kg plant⁻¹, and Kg plant⁻¹, respectively
The LS means are presented as the range for F1 and as absolute means for the parents (3010 and CW 1010). The CSB is the cumulative summer biomass yield harvested in 3 subsequent cuts
^aRange of LS means of trait in F1 progeny; ^bParental mean for traits under given environment and year. The two locations included the J. Phil Campbell Sr. Research and Education Center (JPC) in Watkinsville and the Georgia Mountain Research and Education Center (BVL) in Blairsville
