Registration of seven disease‐ and pest‐resistant vegetable soybean germplasm lines

Registration of seven disease‐ and pest‐resistant vegetable soybean germplasm lines Soybean [Glycine max (L.) Merr.] germplasm lines LB18‐49 (Reg. no. GP‐448, PI 699118), LB18‐52 (Reg. no. GP‐456, PI 699119), LB18‐57 (Reg. no. GP‐455, PI 699120), LB18‐58 (Reg. no. GP‐454, PI 699487), LB18‐65 (Reg. no. GP‐453, PI 699488), LB18‐67 (Reg. no. GP‐452, PI 699489), and LB18‐75 (Reg. no. GP‐451, PI 699121) are large seeded, non‐genetically modified organism soybean lines ranging in maturity from maturity group (MG) 00 through MG IV. Each line contains a single gene for resistance to soybean aphid or Phytophthora root and stem rot (PRSR). LB18‐49 and LB18‐58 have resistance to soybean aphid biotype 3 (Rag1) provided by LD06‐16721. Soybean aphid resistance to biotype 2 (Rag2) was derived from LD08‐12441 for LB18‐65. LD08‐12582 provided Rag2 resistance for LB18‐52 and LB18‐57. ‘Williams 82’ was the source of the PRSR resistance gene, Rps1k, for LB18‐67 and LB18‐75. Large‐seeded cultivars ‘Tohya’ (MG 00), ‘BeSweet 2001’ (MG II), ‘Gardensoy 24’ (MG II), and ‘Gardensoy 41’ (MG IV) served as recurrent parents with pest‐resistant donor lines to develop large‐seeded, pest‐resistant soybean lines in a range of maturity groups. The combined pest resistance and large seed size, in a range of maturities, will be valuable for breeders developing large‐seeded pest‐resistant cultivars. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Plant Registrations Wiley

Abstract

Soybean [Glycine max (L.) Merr.] germplasm lines LB18‐49 (Reg. no. GP‐448, PI 699118), LB18‐52 (Reg. no. GP‐456, PI 699119), LB18‐57 (Reg. no. GP‐455, PI 699120), LB18‐58 (Reg. no. GP‐454, PI 699487), LB18‐65 (Reg. no. GP‐453, PI 699488), LB18‐67 (Reg. no. GP‐452, PI 699489), and LB18‐75 (Reg. no. GP‐451, PI 699121) are large seeded, non‐genetically modified organism soybean lines ranging in maturity from maturity group (MG) 00 through MG IV. Each line contains a single gene for resistance to soybean aphid or Phytophthora root and stem rot (PRSR). LB18‐49 and LB18‐58 have resistance to soybean aphid biotype 3 (Rag1) provided by LD06‐16721. Soybean aphid resistance to biotype 2 (Rag2) was derived from LD08‐12441 for LB18‐65.

Large‐seeded cultivars ‘Tohya’ (MG 00), ‘BeSweet 2001’ (MG II), ‘Gardensoy 24’ (MG II), and ‘Gardensoy 41’ (MG IV) served as recurrent parents with pest‐resistant donor lines to develop large‐seeded, pest‐resistant soybean lines in a range of maturity groups.
