Laser induced mutagenesis of a new onion variety"Keweihong 10"research on breeding and cultivation techniques
He-Ne laser was used to irradiate 5000 wet seeds of red skinned short-day onion variety"Hong 0807"for 10 min,20 min,30 min,40 min and 50 min respectively at 3 mW,6 mW and 9 mW.Aiming at onion varieties with high yield,early maturity and low bolting rate were selected from the variation offspring of laser irradiated onion.After variety comparison regional and field production test,new onion varieties were selected.The average yield per hectare of this variety is 84 233.7 kg,which was 17.04％higher than that of the control variety"Xichong 2"and 20.22％higher than that of the parent"Hong 0807",and the yield increase was extremely significant;The bolting rate was 3.58％,which was 18.08％lower than that of the parents.The maturation period was about 175 days,showing early maturity.The variety is named"Kewei Red 10".In 2023 it was recognized by the Non Major Crop Variety Committee of Sichuan Province(Sichuan Cergified Vegetables 2023009).
