RESEARCH OF WHEAT ELITE PARENT NINGMAI 9 AND ITS UTILIZATION
摘要
Abstract
Ningmai 9 is a soft wheat cultivar with high and stable yield, broad adaptation, moderate resistance to fusarium head blight (FHB) and high resistance to wheat spindle streak mosaic virus (WSSMV). The ten new wheat cultivars derived from Ningmai 9 have become or will soon be becoming the leading cultivars in the mid-lower reaches of the Yangtze River. In order to explore the value of Ningmai 9 as a crossing parent in wheat breeding program, the physiological basis for high yield and genetic characters for yield, quality and disease resistance of Ningmai 9 were analyzed, meanwhile the main features of its ten derivatives were also described. The results showed that Ningmai 9 had high photosynthetic capacity, water use efficiency and drought resistance, and its high-yielding potentiality was mainly determined by more spikes per unit and grains per spike. The cultivar had high general combining ability in many characters such as grains per spike, harvest index, protein content, alkaline water retention capacity and disease resistance which were easily passed to its derivatives. As a direct parent, the ten excellent cuhivars Ningmai 13, Ningmai 14, Ningmai 16, Shengxuan 4, Shengxuan 6, Yangmai 18, Yangfumai 4, Zhenmai 5, Zhenmai 8 and Nannong 0686 were developed by various breeding methods, and all these derivatives maintained its excellent traits such as high and stable yield, moderate resistance to FHB, and resistance to WSSMV. Therefore, it was concluded that Ningmai 9 was an elite parent with high general combining ability, and it had important value for developing the new wheat cultivars high-yielding, better quality and disease resistance.关键词
