Large-scale yield trials have traditionally been used to rate the reactions of released sugarcane varieties to ratoon stunting disease (RSD). These trials are time-consuming and require large tracts of land and are therefore not suitable for incorporation into a routine programme of disease screening of new genotypes. Using a tissue blot-enzyme immunoassay (TBIA) to determine the percentage of ...

Maize silage is forage of high quality and yield, and represents the second most important use of maize in the United States. The Wisconsin Quality Synthetic (WQS) maize population has undergone five cycles of recurrent selection for silage yield and composition, resulting in a genetically improved population. The application of high-density molecular markers allows breeders and geneticists to ...

We propose a new DDQ testing signature, the graphical DDQ signature. We discovered that noise, in the entire set of current measurements for a chip, is a vastly superior feature for classifying chips as good or bad, compared to present methods. The measured DDQ current as a function of vectors is defined here as the signature. We examine the shape of the waveform defined by the total set of the...

Increasing concerns about the environmental impacts of herbicides, the development of herbicide-resistant weeds, and the need to carefully weigh costs and benefits have led to greater interest in developing rational, economical, and sustainable approaches to weed management (O'Donovan 1996). In addition, greater emphasis on post-emergence applied herbicides such as glyphosate has allowed for mo...

Yields of four soybean cultivars were measured for 4 years in a field infested with Heterodera glycines race 3 and in a field infested with H. glycines race 14. Cultivars included Hutcheson (susceptible to both races), Deltapine 415 (resistant to race 3 and susceptible to race 14), Asgrow 5979 (resistant to both races), and Harwig (resistant to both races as well as most other known races of H....

The measured IDDQ current as a function of vectors is defined here as the IDDQ signature of a chip. We examined the IDDQ signatures of a large number of SEMATECH chips that have been classified us good or bud by a combined decision from functional, delay and scan tests. We find that a single IDDQ threshold, whether absolute or differential, cannot separate good/bud chips with any desirable accu...
