Statistical analyses for phenotyping fresh weight (FW), relative water content (RWC) and drought resistance index (DRI) in 198 alfalfa accessions.

Notes: CV, coefficient of variation. H2, broad-sense heritability based on accession mean. GCV, genetic variation coefficient. Max = maximum, Min = minimum, Ave = average.
“*” and “**”, significance at P≤0.05 and 0.01, respectively.

注：变异系数（CV，coefficient of variation）、基于种质材料均值的广义遗传力（H₂，broad-sense heritability）以及遗传变异系数（GCV，genetic variation coefficient）；其中Max、Min、Ave分别对应最大值（maximum）、最小值（minimum）与平均值（average）。*与**分别代表在P≤0.05和P≤0.01水平下具有统计学显著性。本研究针对198份苜蓿种质材料的鲜重（fresh weight，FW）、相对含水量（relative water content，RWC）及抗旱指数（drought resistance index，DRI）开展表型性状统计分析。
