| Abstract: | By irradiating cucumber dry seeds of a inbred line with 60 Coγ of 90 000 roentgen,mutants ohich had exellent comprehensive traits were obtained.After 3 generations of inbreeding and selecting,the inbred line,M-8,which had sveral beneficial traits was developed.And a new F1(93-5),which was tolerant to low temperature and low intensity light,and suitable for plastic greenhouse cultivation,was derived by crossing M-8 with another inbred line.The hybrid was earlier muturing,higher yield and more resis... |
