Correlation Analysis of Yield Characters and Nitrogen Utilization Characteristics in Northern Rice Germplasm Resources
摘要
Abstract
Take 129 rice germplasm resources of Northern China as test materials, nitrogen absorption and utilization characteristics (NAUC) under different nitrogen fertilizer conditions were identified and evaluated; the regressive equation of the yield and nitrogen utilization characteristics were established. And a comprehensive appraisal indicator system (CAIS) of NAUC was established. The results indicated that: all yield characters including PH PL BW HI PN PGN SSR KGW were deduced 5,5 and 6 composite factors at high, middle and low nitrogen condition respectively, each factor integrated the information of all the agronomic traits to some extent. At high nitrogen condition, the F2 and F5 factor were significantly related to some of the NAUC, so did the F1, F3 and F4 factor at middle nitrogen condition, and the F1, F2, F4 and F5 factor at low nitrogen condition. There were significant conic regression equations between those related factors and NSUC.关键词
