Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(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
PI 651794
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0PI 665928'M713 Ren1'Gossypium hirsutum L. Mississippi, United StatesCOTNot Available2012DEVELOPEDBreeding materialM713 Ren1 was developed by marker assisted selection. The reniform nematode resistance in GB-713 is significantly associated with three QTLs, Ren barb1 and Ren barb2 located on chromosome 21 and Ren barb3 located on chromosome 18 (Osman et al. 2011 Theor Appl Genect 122:271-280). M713 Ren1 is homozygous (SSR markers GH 132_201, BNL3279_106, BNL4011_152 and BNL569_131) for three QTLs (Ren barb1, Ren barb2 and Ren barb3). Reniform nematode, Rotylenchulus reniformis, was verified in greenhouse test. Reniform nematode egg production was reduced approximately 90% compared to a susceptible cultivar. Over-all plant size is similar to standard cultivars. M713 Ren1 offers an excellent source of resistance to the reniform nematode with acceptable agronomic and fiber traits and by using marker assisted selection the development of reniform resistant cultivars should be expedited.1904833PI 665928

The reniform nematode resistance in GB-713 is significantly associated with three QTLs, Ren barb1 and Ren barb2 located on chromosome 21 and Ren barb3 located on chromosome 18 (Osman et al. 2011 Theor Appl Genect 122:271-280). M713 Ren5 is homozygous (SSR markers GH 132_201, BNL3279_106, and BNL4011_152 ) for two QTLs (Ren barb1, and Ren barb2). Reniform nematode, Rotylenchulus reniformis, was verified in greenhouse test. Reniform nematode egg production was reduced approximately 90% compared to a susceptible cultivar. Over-all plant size is similar to standard cultivars. M713 Ren5 has green seed fuzz and offers an excellent source of resistance to the reniform nematode with acceptable agronomic and fiber traits and by using marker assisted selection the development of reniform resistant cultivars should be expedited.1904835PI 665930
