(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

0PI 643397LM-1Oryza sativa L. Louisiana, United StatesNSGCKERNELS2006DEVELOPEDBreeding materialLM-1 is a short stature mutant that averaged 0.86 m in height compared to 0.90 m for Lemont and 0.92 m for Cocodrie (PI 606331) The line is similar to Lemont in plant type having light green broad leaves but heads approximately 3-4 days later. LM-1 had an average sheath blight rating of 4.6 on a 0-9 rating scale, where 0 indicates immunity and 9 indicates very susceptible, after inoculation with the sheath blight fungus, indicating moderate resistance to sheath blight as compared to 8.0 and 7.8 ratings for the very susceptible cultivars Lemont and Cocodrie respectively. When inoculated with bacterial panicle blight the line rated 1.6 (very resistant), on a 0-9 rating scale, where again 0 indicates immunity and 9 indicates very susceptible, as compared to 4.2 and 7.0 for the moderately susceptible and susceptible varieties Lemont and Cocodrie respectively. The line also express immunity to narrow brown leaf spot rating 0.0 on a 0-9 scale compared to 2.3 for Lemont and 3.3 for Cocodrie under light natural disease pressure.

Louisiana, United StatesNSGCKERNELS2006DEVELOPEDBreeding materialLMT-1 is a slightly taller stature mutant that averaged 0.88 m in height compared to 0.90 m for Lemont and 0.92 m for Cocodrie (PI 606331) The line is similar to Lemont in plant type having light green broad leaves but heads approximately 3-4 days later.
