In the present study, identification of a potential isolate for biocontrol experiments involved dual culture assays as a screening strategy against the spot blotch
Comprehensive genetic analyses reveal differential expression of spot blotch
resistance in four populations of barley.
Each central blotch
is an outsize monument to the material residue of the density of urban life as well as witness to a morcellated subjectivity assailed by the technologies that cut it down the middle or split it apart.
Gill cover with distinct golden sheen, continued along side between blotch
rows H3 and H4.
In this study, we developed an AB population with the wild barley accession OUH602 as a resistance donor and Harrington as a recurrent parent to (i) validate resistance QTLs for the foliar diseases identified in our OUH602/Harrington RIL population, (ii) determine the genomic location of adult plant spot blotch
resistance, (iii) assess the genetic characteristics of the AB population, and (iv) provide access to novel OUH602 alleles in an adapted genetic background for further breeding and genetics applications.
Overall, mean tail blotch
counts were higher for males than females (t = 5.
Most of the red blotch
I've seen in the Foothills has a pattern that suggests it came in with planting material.
7% SL; anterior extent of predorsal squamation reaching anteriorly to vertical through posterior margin of preopercle, with a few scales sometimes extending slightly beyond this point; first dorsal fin elements with 2-3 dark blotches
on each element giving appearance of 2-3 longitudinal stripes across fin; lower body with two rows of dark spots, spots in two rows directly above one another, beginning immediately behind pectoral fin base and terminating just anterior to dark blotch
at base of caudal fin; upper and lower spots more distinctly separate from one another anteriorly, becoming closer to one another and loosely connected posteriorly; arrangement of spots appearing as 6 to 7 sets of vertically paired spots often forming "=" shaped markings along ventral portion of trunk.
In our routine field trials at Banaras Hindu University, Varanasi, India, we observed that genotypes that had leaf tip necrosis showed lesser spot blotch
development than those without this trait (Joshi and Chand, unpublished data, 1998).
2 illustrates the highest degree observed of secondary splitting of dorsal blotches
, yielding a possible count of 47 in an animal basically with fewer, certainly no more than 44; because of this ambiguity its dorsal blotch
count was not entered in the statistical analyses.
Overall, they studied 10 males of known age and 26 whose ages were estimated based on the extent of blotch
darkening when first observed.
A total of 86% of the 200 farmers surveyed by agri-business Sygenta pinpointed rhynchosporium, while 60% included net blotch
, 53% mildew and 42% rust in their lists of problems.
