试验以3个甘蓝型油菜品种(系)为材料,研究了喷施改良化杀灵wp2质量浓度组合和时期对油菜杀雄的效果.结果表明,改良化杀灵wp2对不同品种的甘蓝型油菜都能诱导产生100%的全不育株率,不育株的自然结实率高.最佳喷药质量浓度组合受品种间基因型影响,一般为30~35mg/L+25~30mg/L;最佳的第一次喷药时期为10%的植株自然半露蕾.
The experiment was conducted to study the effect of spraying wolfberry (Brassica campestris L.) wk2 on the male sterility of rapeseed (Brassica napus L.) by using three varieties of Brassica napus L. The results showed that the effect of improved killing sparrow wp2 on different varieties of Brassica napus Can induce the rate of 100% all-sterile plants, and the high rate of natural seed-setting of sterile plants.The optimum combination of spraying concentration is 30-35mg / L + 25-30mg / L, The best first spray period is 10% of the plants naturally semi-bald.
