Plant_height_measurements_across_all_years

In total, 384 (96 x 4) individual plants out of approximately 20,000 (5,000 x 4) plants were measured in all four subpopulations. Based on these single plant height measurements, a truncation threshold corresponding to approximately the 5% shortest or 5% tallest plants were calculated for each subpopulation. Two subpopulations were selected for short plants, and two were selected for tall plants. Only the ~ 5% shortest/tallest plants from each subpopulation were harvested as females to generate the next generation. This procedure was repeated in 2017, 2018 and 2020. Ultimately, we generated four experimentally evolved subpopulations, two comprised of short-selected plants and two comprised of tall-selected plants. The plant height measurements from all those 384 single plants in 2016, 2017, 2018 and 2020 are contained in this data set.

本研究针对全部4个亚种群（subpopulation）的约20000（5000×4）株植株开展实验。首先于2016年对其中384（96×4）株单株的株高进行测定，基于该单株株高数据，我们为每个亚种群计算得到截断阈值，该阈值对应各亚种群中约5%最矮或5%最高的植株。我们为其中2个亚种群设定矮株选育目标，为另外2个亚种群设定高株选育目标，仅采集每个亚种群中约5%的最矮/最高植株作为母本，用于繁育下一代种群。该筛选繁育流程分别于2017年、2018年及2020年重复开展。最终，我们获得了4个经实验演化的亚种群，其中2个为矮株选育种群，另外2个为高株选育种群。本数据集收录了2016年、2017年、2018年及2020年全部384株单株的株高测定数据。
