Release of DES 607 and Licensing of H10-35-05

J. B. Creech, R. R. Bridge and D. S. Calhoun


 
ABSTRACT

‘DES 607' cotton (Gossypium hirsutum L.) was developed at the Delta Research and Extension Center, Mississippi Agricultural and Forestry Experiment Station (MAFES), Stoneville, MS. In 1998, marketing rights to DES 607 were licensed exclusively, through a competitive bid process, to Deltapine Seed of Scott, MS.

DES 607 was developed from the progeny of a cross made in 1986 between ‘DES 920' and ‘Deltapine 20.' DES 920 originated from a 1977 cross between ‘ST 870IN' (nectariless line) and ‘DES S11-9'. DES S11-9 was the bulk population from which ‘DES 119' was selected. DES 920 was later released as a germplasm line in 1990. Deltapine 20 is a commercial cultivar widely grown throughout the Mid-South. Progeny of this cross were selected individually in the F2 generation. Progeny of the F2 selection, ‘F07-30', which gave rise to the current strain, were yield tested in the F4 generation and re-selected in the F5 generation. An F6 progeny row of the selection, ‘F07-30-17', was harvested as a bulk and seed has been increased since that time without further selection except to remove any off-type plants resulting from mechanical mixing.

‘H10-35-05', an experimental line of cotton (Gossypium hirsutum L.) was developed at the Delta Research and Extension Center, MAFES, Stoneville, MS. In 1998, marketing rights to H10-35-05 were licensed exclusively to Mycogen Corporation of San Diego, CA.

In brief, H10-35-05 was developed from the progeny of a cross that was made in 1988 between ‘DES 949' and ‘Acala 1517-88'. DES949 is a selection out of DES 119. Acala 1517-88 is a commercial cultivar developed by New Mexico Agricultural Experiment Station and released in 1987. The F1 of ‘H-10' was grown in Mexico in 1988-1989 and the F2 was grown at Stoneville, MS in 1989. Progeny of this cross were selected individually (37 plants selected) in the F2 generation and one plant became ‘H10-35'. The F3 was grown in progeny rows at Stoneville, MS in 1990. H10-35 was yield tested in the F4 generation and re-selected in the F5 generation. An F6 progeny row of the selection, H10-35-05, was harvested as a bulk and seed has been increased since that time without further selection except to remove off-type plants. In 1998, H10-35-05 was tested at multiple locations by Phytogen Seed Company under the variety name ‘PSC 355'. Phytogen Seed Company, LLC. is a joint venture between Mycogen Corporation and J. G. Boswell Company.
