改良化杀灵wp2对甘蓝型油菜杀雄效果研究
Effects of Modified Huashaling wp2 on Male Sterilizing Effect of Rapeseed (Brassica napus L.)

摘要: 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w p2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w p2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30～35 m g／L＋25～30 m g／L ；最佳的第一次喷药时期为10％的植株自然半露蕾。

Abstract: One cultivar and two lines of Brassica napus were used as materials to study the male sterilizing effects of spraying concentrations and stages of wp2 .It indicated that the Huashaling wp2 could induce 100% of the plants showing complete male sterility .The induced male sterile plants had high natural seed‐set ability .The most appropriate concentration combination of wp2 was affected by genotypes of the culti‐vars ,which was 30~35+ 25~30 mg/L generally .The optimal stage of the firt spraying was the time w hen 10% of the plants displayed the half presented buds naturally . -
