激光育种是六十年代兴起的一种育种方法.我所根据一九七五年全区激光育种协作会议的精神,开展了蓖麻蚕激光育种工作,育成了“南激一号”等几个材料.现将实验情况小结如下.一、“南激一号”的选育,是在一九七五年三月开始,选用现行蓖麻蚕品种“南宁一号”纯种,嫩蛹期用氦一氖激光照射雌、雄蛹第五腹节的左右两侧(气门)各5分钟,照射功率密度43毫瓦/平方厘米.照射后即将蛹放在蚕室自然温度下保护繁育.当代饲养二区,从第二代开始饲养6-8区,每区以5蛾卵混合收蚁一克饲养,着重蛾区混合选择,结
Laser breeding is a breeding method that emerged in the 1960s, and according to the spirit of the Collaborative Conference on Laser Breeding in 1975, we carried out the laser breeding of castor silkworm silkworm, bred “Nanking One” and so on Several materials are now experimental conditions are summarized as follows: First, “South shock one ” breeding, is in March 1975, the current castor silkworm varieties “Nanning One ” pure Species, pupal stage Helium-neon laser irradiation female and male pupa on the right and left sides of the fifth abdominal section (valve) for 5 minutes, irradiation power density of 43 milliwatts / square centimeter.After irradiation pupation on the natural temperature in the room Protection of breeding. Contemporary feeding two districts, starting from the second generation of raising 6-8 area, each district to take five moth eggs mixed income one gram breeding, focusing on mixed selection of moths, knot
