The leaf area measuring instrument for studying the genetic mechanism of the three-leaf area of ​​the ear, especially the leaf area of ​​the ear, is of great significance for efficient breeding of high-yield, high-quality, disease-resistant, and wide-adapted maize hybrids. In the field of QTL mapping of crop leaf area, there are many studies on rice, especially a large number of QTL mappings for the shape and size of rice flag leaves. In the study of QTLs for leaf area of ​​corn, the leaf area of ​​the ear was relatively less reported.
A normal distribution test was performed on the leaf area of ​​the ear of the F2 plant. The statistics of the leaf area meter showed that the variation of the leaf area character of the panicle was larger in the view of the amplitude and variation coefficient; The area does not deviate significantly from the normal distribution, and meets the basic requirements for QTL positioning. QTL detection can be performed.
The agronomic traits such as plant height, leaf area measurement, and yield are the quantitative traits. Since the 1980s, the rapid development of molecular marker technology and QTL mapping methods has provided a powerful tool for the study of complex quantitative traits. With the rapid development of molecular genetics, molecular marker linkage maps of many major crops (rice, corn, wheat) have been constructed at home and abroad, and combined with QTL mapping and genetic analysis of agronomic traits with instrumentation of leaf area meters. The foundation.
High yield is the goal of eternal pursuit of corn breeding, which also shows that the impact on its yield is composed of multiple factors. Ear yield traits are its direct manifestations. Leaf is the main organ of photosynthesis in corn, and leaf area is an important indicator for determining photosynthetic products, which plays an important role in the formation of yield. The leaf area measurement instrument showed that there was a significant positive correlation between the three-leaf area of ​​maize ear and the yield per plant of maize, and the leaf area of ​​the ear was most closely related to the yield.
