A Study on the Optimized Model of Yield Components for Hybrid Wheat

doi:10.3321/j.issn:1000-7091.1999.01.003

Abstract

Abstract: The optimization of yield components was conducted for hybrid wheat at yield level from 8250 kg to 12000 kg/hm² based on the relationship between yield components in current hybrid wheat. The analysis of optimized models showed that the kernel number per spike and thousand kernel weight should be increased on the basis of proper number of spikes in unit area, specially increasing kernel number per spike. Threr were diversity and regularity among optimized models of yield components established in this paper.

Key words: Hybrid wheat, Yield component, Optimized model
