Abstract
[Objective] The aim was to clear effects of main agronomic traits and fresh ear yield of waxy corn to provide theoretical basis for breeding and cultivation of good quality and high yield waxy corn in Sichuan Province.[Method] We analyzed the relationships between 10 agronomic traits and fresh ear yield of waxy corn by grey relational analysis.[Result] It showed that fresh ear yield was closely related to spikelength,growth period,ear diameter and bald tip length,and the next were kernel per row,plant height,ear height,row per ear,kernel weight and kernel rate.The spikelength was the main factor affecting fresh ear yield of waxy corn,while the kernel rate had less effect on yield.[Conclusion] It should take spikelength,growth period,ear diameter and bald tip length as main breeding objectives to accelerate the effective selection of fresh waxy com.关键词
