The correlation and path analysis on relationship between the academic achievement and social responsibility for teachers were studied in university in Chongqing. The results showed that the social responsibility for teachers had significant positive correlations with the title of outstanding teachers, to upgrading diploma, paper, and revenue in last 3 years. And revenue had the most positive influence on the social responsibility for teachers with the direct path coefficient 0.7891, the average number of teaching hours had the most negative influence on the social responsibility for teachers with the direct path coefficient-0.0184. The influence order of other characters was the title of outstanding teachers (0.2438), paper (0.0535), to upgrading diploma (0.0329), and as academic leaders or key teachers (0.0301). © 2011 Springer-Verlag Berlin Heidelberg.

A maize F 2 population was first used to construct a genetic linkage map of Chromosome 6 covering 117. 6 cM with an average interval of 3. 68 cM between adjacent markers. Based on composite interval mapping (CIM), the quantitative trait loci (QTL) for phosphorus absorption efficiency (PAE) and root-related traits was detected in four environments, i. e., Kaixian County under deficient phosphorus (KXDP), Kaixian County under normal phosphorus (KXNP), SUDP1, and SUDP2. QTLs affecting root weight (RW) were detected simultaneously at the dupssr15 locus region (bin 6. 06) on Chromosome 6 in the four environments, while QTL affecting taproot length and fiber number was only detected in one or two environments. The result suggested that taproot length and fiber number were more easily affected by the environment than PAE and RW. The alleles originating from 082 increased PAE and RW on Chromosome 6. The QTL on bin 6. 06 explained 4%-10% and 4%-8% of the total phenotypic variance of PAE and RW, respectively, and the estimates of the genetic effects presented dominance and overdominance. The QTL for RW in the dupssr15 locus is the minor QTLs environment interactive effects, which should be particularly useful in MAS manipulation of breeding maize. © 2011 Higher Education Press and Springer-Verlag Berlin Heidelberg.
