Abstract

Abstract:

The aim was to investigate the dynamic changes in filament vitality and seed setting of different maize inbred lines. This study used maize inbred lines ‘Xun 696’, ‘Xun 573’, ‘Xun 503’, ‘Zheng 58’ and ‘Chang 7-2’ as experimental materials to measure relevant indicators such as daily filament length and quantity, filament setting rates and ear traits at different days. The results showed that the daily filament length and filament setting rate of different inbred lines increased first and then decreased; the peak of the daily spinning length of the flower silk was on the 2^nd to 3^rd day of spinning; the peak setting rate was on the 3^rd to 5^th day of silk spinning. The daily filament amount showed a ‘fast-slow’ growth pattern, with a rapid growth from the 1^st to the 3^rd days. The total amount of ‘Xun 696’ filament was the smallest, and the total amount of ‘Chang 7-2’ filament was the largest. On the 8^th day after pollination, the fertilization rate and total fruiting rate of small flowers were higher than that on the 5^th day, with ‘Zheng 58’ having the highest fertilization rate and ‘Xun 696’ having the highest total fruiting rate. The fruiting rate of silk at different days of age in ‘Xun 696’, ‘Xun 573’, and ‘Xun 503’ was significantly or extreme significantly positively correlated with various traits of their panicles, daily silk production, and silk production length. The research results provide a theoretical basis for clarifying the active time of the filaments of inbred lines, mastering the optimal pollination period, improving the seed setting and seed production yield of inbred lines.
