Abstract

Abstract:

In order to explore the correlation between peanut sucrose content and meteorological factors and quality traits such as oil, protein, oleic acid and linoleic acid content, the experimental materials were planted in the warm and cold areas for two consecutive years, and field agronomic date, yield data and meteorological data were collected. The quality of the test materials was analyzed by Perten DA7250 near-infrared spectrometer. The difference of sucrose content was evaluated by simple comparison, correlation analysis and grey correlation analysis. The average sucrose contents of the experimental materials in the cold and warm areas were 5.823% and 1.908%, respectively. The sucrose contents of W26, W172, W225, W239, W251, W377 and W411 germplasm were >2.5% in the warm region and >6% in the cold region. The sucrose content of peanut seed kernel was closely related to the temperature during the growth period, and was significantly negatively correlated with the average maximum temperature at the podding stage, and was significantly negatively correlated with the average minimum temperature, average temperature and≥10℃ accumulated temperature from the flowering stage to the maturity stage. The results of grey correlation analysis showed that the factors affecting sucrose content were average maximum temperature > average minimum temperature > average temperature > accumulated temperature. There was a significant negative correlation between sucrose content and oil content. The average sucrose content in the cold and warm areas differed by 3.915 %. The sucrose content of peanut is greatly affected by high temperature during the growth period. Low temperature is more conducive to the accumulation of sucrose content in peanut kernels. Reducing the oil content of peanut varieties may help to increase the sucrose content of peanuts. And seven germplasms with high sucrose content in different habitats were screened out.

Key words: peanut, sucrose content, meteorological factors, correlation analysis, grey correlation analysis
