Abstract:
Abstract:Taking Festuca rubra varieties of ‘Red festuca’ and ‘Benjamin’ from space flight as materials,the mutagenic effect of space flight on the two varieties of Festuca rubra in SP2 were studied.The results showed that the variability coefficient of plant height,grass layer height,length of leaf,width of leaf,ear length,number of spikelets and seeds number per spikelet in the two materials were higher than those of the earth control,and these traits had produced two-way mutations.Some traits of plant height,grass layer height,length of leaf and ear length in the two materials had a positive tendency,the width of leaf tended to narrowing trend；the number of spikelets of ‘Red festuca’ tended to increasing trend and seeds number per spikelet tended to decreasing trend,the number of spikelets of ‘Benjamin’ tended to decreasing trend and seeds number per spikelet tended to increasing trend.The variability changes of SP2 offspring showed that space treatment provide new germplasm for Festuca rubra breeding effectively.
