Abstract

Abstract: Molecular test and insect bioassays with aphid (Myzus persicae Sulzer) larvae verified that gna gene had been integrated into Chinese cabbage genome mediated by Agrobacterium tumefaciem ，and all 7 transgenic plants were aphid resistant，strong mRNA of gna could be detected in transgenic plants with higher insect resistance. The results of inheritance analysis showed foreign gene in 2 transgenic Chinese cabbage plants 282-3 and 282-9 is in the model of the simple Mendel’s fashion in their T₁ progenies.

Key words: Chinese cabbage, gna, Expression, Inheritance, Aphid resistance
