[Method] Recombined inbreed lines (RILS) of Chuanmai 42 (LMA genotype) crossed with Chuannong 16 (no LMA) were employed to test the late maturity α-amylase (LMA) by EL ISA kits,the Falling Number (FN),and three QTL,SSR markers (Xgwm 577,Xwmc276,Xwmc273) of LMA gene. [Result] Results suggested that LMA was controlled by a single,and the three SSR markers seemed to be not efficient to test LMA gene in this RILS. LMA was an important factor on FN,meanwhile FN was also affected by other factors. [Conclusion] The study could provide references for the breed of quality wheat.展开更多

Otherwise the risk of a high visibility false alarm outweighs the benefit of a correct early hit. Yet automated forecasts may occasionally include record values beyond day 2, which forecasters may choose to downplay, or not. In Canada, forecasters keep their focus on high impact weather for days l and 2, so that forecasts for day 3 and beyond are mostly automated and usually released after a quick glance. So a process was designed to bring up cases where automated temperature forecasts exceed known records for a number of sites, with the sole purpose of alerting the forecasters who may decide whether or not modifications are needed before release. As a by-product it is found that some record temperature forecasts are issued every day in Canada, even more records are actually observed, and in recent years there have been twice as many new high records as low ones. We discuss the origin of the process, its logics, its current status, interesting findings, and possible improvements.展开更多
