Genetic analysis for anthocyanin and chlorophyll contents in rapeseed

ABSTRACT: Rapeseed ( Brassica napus L.) with purple-red leaf is a valuable resource for plant breeder. It was utilized in breeding program as a morphological marker, and the source of resistance gene to biotic or abiotic stress due to its anthocyanin content (AC). However, the inheritance of AC and the correlation with chlorophyll content (CC) in rapeseed leaf are still unknown. This study aimed to investigate the gene action and heritability of AC and CC in a 10-Zi006 × 10-4438 rapeseed cross using generation mean analysis. The results indicated that AC and CC were controlled by main gene effect and non-allelic interactions. The AC was mainly controlled by genetic effect. However, the genetic effect and non-genetic effect were both important for CC. In addition, the total fixable gene effects was higher than unfixable gene effects for AC, but opposite results was found for CC. Both negative and positive correlations between AC and CC were obtained in different generations

The Research of Motion Planning of Humanoid Robot

Abstract: This paper proposed a strategy for humanoid robot motion planning using GA-based fuzzy neural network controller, which is stable self-learning fuzzy neural networks control system. The system is composed of two parts: (1) A FNNC which use GA to search optimal fuzzy rules and membership function; (2) A supervisor which use gradient learning algorithm to train the network weights. And we apply this controller to robot motion planning. The simulation result shows its effectiveness
