in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

The problem of estimating heading is central in the indoor positioning problem based on measurements from inertial measurement and magnetic units. Integrating rate of turn angular rate gives the heading with unknown initial condition and a linear drift over time, while the magnetometer gives absolute heading, but where long segments of data are useless in practice because of magnetic disturbanc...

Frequent extreme heat events are the serious threat to rice production, but the historical trend of heat stress associated with phenology shift and its impact on rice yield over a long period are poorly known. Based on the analysis of observed climate and phenology data from 228 stations in South China during 1981-2010, the spatio-temporal variation of post-heading heat stress was investigated ...
