摘要

采用4种不同剂量的物理诱变剂(100、200、300和400 Gy)和4种不同浓度的化学诱变剂(5、10、15和20 mM)，以及这两种诱变剂的组合，诱导草品种“Pusa-24”的花色突变体。通过诱变获得了广泛的花色突变体m2、m3和m4。在对照后代中检测到粉红色、紫色、白色和黄色等各种独特和不同的花色突变，而蓝色是自然色。第4代EMS处理种子的花色频率最高(20 mM)，第2代γ射线处理种子的花色频率最低(100 Gy)。结果表明，每代诱变剂剂量/浓度越大，发生的花色突变越多

Gamma rays and EMS induced Flower Color Mutation in Grasspea (Lathyrus sativus Linn.)

To induce flower color mutants in Grasspea ( Lathyrus sativus Linn.) variety “Pusa-24“, the fresh seeds were exposed to 4 different doses of gamma radiation as physical mutagens (100, 200, 300 and 400 Gy) and treated with 4 different concentration of Ethyl Methanesulphonate as chemical mutagen (5, 10, 15 and 20 mM ) and also combination of both mutagens. Due to mutagenesis broad range of flower color mutants in M 2 , M 3 and M 4 were obtained. Various unique and different flower color mutations like pink, purple, white and yellow detected against blue which is natural color in control progenies. Maximum flower color frequency was recorded in EMS treated seeds (20 mM) in 4th generation and lowest mutation frequency in 2nd generation was obtained in gamma rays (100 Gy) treated seeds. The results showed more flower color mutations happened in more dose /concentration of mutagens in every generation
