Because unfriendly temperatures kill the aphids that vector BYDV in the fall planting near or after the first freeze is a good way to avoid BYDV pollutions.
These DNA segments are added to DNA of plants the scientists think might be carriers of the wheatgrass chromosome with the BYDV resistance trait.
Rochow (1969) originally separated BYDV into several strains (formerly considered isolates or strains) based on their ability to be transmitted by different species of aphid vectors, and the current virus designations reflect the most common transmission pattern.
Dominant gene Bdv1and Bdv2confers tolerance to BYDV in some wheat varieties that induces slow yellowing.
This provides a basic mechanism for the observation in some studies that aphids prefer plants infected with BYDV over healthy plants.
ELISA values in a four-replicate test, 14 d after infestation with aphids viruliferous for BYDV and CYDV, for P961341 and Abe were, respectively, 0.
In 1999, plots were rated for severity of crown rust and BYDV within the 2 wk following heading date in four and three environments, respectively, using a nine-point combined scale of incidence and severity (Helland and Holland, 2001).
1998), and for this report we examined the inheritance of a BYDV coat protein gene and bar, and the expression of bar as measured by resistance to glufosinate-ammonium damage, in the progeny of seven independent transformation events through the [T.
NC Hulless is resistant to prevalent races of crown rust in North Carolina and it has a moderate level of tolerance to BYDV.
