ABSTRACT
Yuhua91 is a new peanut variety with high oleic acid content bred by Qingdao Agricultural University. The crossing was conducted with Luhua11 as female parent and with Kainong1715, an F435-type variety with high oleic acid content as male parent. The real F1 hybrids were screened by sequencing on PCR amplification products, and those homozygotes with bb genotype in F2 populations were screened by the same sequencing method as above. The content of oleic and linoleic acid was measured on the kernels harvested from F2 single plants by near infrared ray method, and those kernels whose content of oleic was above 80%, oleic and linoleic acid ratio was above 10.0 were obtained and planted into a row, with pedigree method for subsequent selection breeding. Yuhua91 has some characters of small pod, light and obvious pod texture, 148.06 g per 100 pods, 63.31 g per 100 kernels, 75.15% shelling percentage, long elliptic seed kernel, pink seed coat, without crack, white endotesta. Its content of protein, oil, oleic acid, linoleic acid and palmitic acid was 26.57%, 52.72%, 80.40%, 2.50% and 5.57% respectively. Yuhua91 has other characters of strong seedlings, compact pod areas, and moderate resistance to leaf spot disease and bacterial wilt. Average pod yield is 215.79 kg per Mu, 15.27% higher than the control variety Huayu20. Average seed kernels yield is 157.33 kg per Mu, 21.64% higher than the control variety Huayu20. Yuhua 91 has been registered on department of agriculture in 2018, and the registration No. is GPD peanut (2018) 370210, fit for growing in Shandong Province.

Objective To develop a scale suitable for evaluating the scientific research ability of medical workers in Liaoning Province,analyze its reliability and validity to provide a scientific and objective measurement method for the evaluation of scientific research ability of medical workers in Liaoning Province.Methods A survey of 6 577 medical workers in 2 grade and up medical institutions of Liaoning province was carried out by completing a self-assessment scale form of research capacity,5 812 effective questionnaires were collected,335 out of which were used for exploratory factor analysis,5 477 were used for confirmatory factor analysis and reliability and validity analysis.Results The scale of Cronbach's a coefficient is 0.982,the retest reliability is 0.967,the cumulative contribution rate of the four factors extracted by exploratory factor analysis was 80.195％.The validation factor analysis showed that the model fit well (GFI=0.907,AGFI=0.881,CFI=0.962,RMESA=0.076,NFI=0.960,IFI=0.962).Conclusions The research capability scale for Liaoning medical workers has good reliability and validity,which can be used in the evaluation of the research capability of the medical workers in Liaoning province.
