EMS诱变西瓜种子条件分析

摘要

This paper took the "W1-17" watermelon cultivar as material, this material was from the Northeast Agricultural University Watermelon and Muskmelon Breeding Research Laboratory, using EMS as mutagen, using five EMS mutagenesis concentration (0.2%, 0.6%, 1.0%, 1.4%, 1.8%), four processing time (3, 6, 9 and 12 h), analyzed the germination rate, relative germination rate, relative seedling rate after different treatment, final y determined the concentration of EMS 1%, 9 h was the optimum conditions of watermelon strain"W1-17"seeds.%以东北农业大学西甜瓜育种研究室自育的西瓜品系“W1-17”为材料，以EMS为诱变剂，采用5个EMS诱变浓度（0.2%、0.6%、1.0%、1.4%和1.8%），4个处理时间（3、6、9和12 h），分析诱变后种子发芽率、相对出苗率和相对成苗率情况，最终确定EMS处理浓度1.0%、诱导时间9 h为西瓜品系“W1-17”种子最佳诱变条件。
