中国玉米品种改良及其种质基础分析
Improvement of Maize Hybrids and the Analysis of Basal Germplasm in China
摘要
Abstract
Improvement of maize hybrids was one of the key factors for the continuous increasing of corn production in China. Under the premise of durative decreasing of cultivated area, the increasing of yield potential by breeding would be crucial for maize production. In this paper, we summarized the contributions of variety improvement to the increasing of yield per unit area in China, the characters of improvement of Chinese maize hybrids and future requirement, as well as the enhancement and status quo of breeding germplasm and potential development in China. Also, we discussed the high density and high nutrient-efficiency breeding strategy in China, the method of germplasm enhancement, and establishment of high efficiency germplasm evaluation & enhancement platform, which were exprected to provide some basic information for maize breeding.关键词
