Maize thousand kernel weight of structural equation modeling analysis and research. (Chinese. English summary) Zbl 1389.62088

Summary: Based on biocharacters of 880 maize samples which were received from the Chinese Crop Germplasm Resources Information System, a structural equation model was built to analyze maize thousand kernel weight of internal factors. The results showed that plant height and ear diameter affect thousand kernel weight significantly, the path coefficients are respectively \(0. 41\), \(0. 42\); in addition, the direct impacts of ear diameter on ear length and ear rows have reached a significant level. This study may indicate the importance of structural equation modeling in crop production research, may introduce breeders to screen high yield maize varieties.
