Effects of Main Agronomic Traits of Wheat on the Resistance of Fusarium Head Blight
摘要
Abstract
[Objective] To investigate main agronomic traits affection on Fusarium head blight (FHB) and provide the reference basis for wheat breeding of resistance FHB. [Method] Two recombinant inbred lines derived from the crosses of Sumai 3 × Annong 2 and Wangshuibai × Annong8455 were evaluated for FHB resistance using natural infection and single-floret injection, respectively. Some correlations were identified between FHB resistance and agronomic traits. [Result] There were significant negative correlations between scabbed spikelet rates of FHB spread and infection with plant height of RIL populations, and also negative correlation with internode length under spike but the significant less, and with spikelet number per spike in most cases no significant correlation. But positive correlation was identified between scabbed spikelet rates of FHB infection with spikelet density. FHB resistance did not show consistent correlations with spikelet length and spikelet number and stem length under the spike in the different years. Spike length and resistance correlation was not stable. [Conclusion] There were not the same between wheat agronomic traits and FHB resistance related for test materials, methods and environment. The genetic and performance of FHB were complex, so wheat breeders could choose moderate plant height, spikelet density and spike length as the primary aims to realize comprehensive character and improve the efficiency of FHB resistance breeding.关键词
