为了验证高能混合粒子场作为诱变源应用在紫花苜蓿品种改良上的效果和价值，将1000粒龙牧803紫花苜蓿干种子平均分为两份，一份由5个剂量（109、145、195、284和560Gy）的高能混合粒子场辐照处理，另一份用和高能粒子场相同5个剂量的^60Co-γ射线辐照处理。对M1和M2株高、产量和品质等表型性状进行统计分析。结果表明：高能粒子处理紫花苜蓿所诱发的突变频率要略高于γ射线，其中高能粒子284Gy的效果最好。

In order to validate effect and value of mixed high energy particle field as mutagenesis source on alfal- fa varieties improvement,Longmu 803 alfalfa dry seeds were used as material, 1000 seed divided into two equal parts,one was irradiated by mixed five doses high-energy particle field（CR）, i. e. , 109,145,195,284 and 560 Gy; the other was irradiated with the same five dosages ^60Co γ-rays. The data of M1 and M2 were collected and analyzed. The results showed that mutation frequency by high-energy particle was higher than by 60 Co γ-rays, and the effect of CR 284 Gy was the best.
