Capital Terr. ACT 2601, Australia. Received 03/23/1994.PI 578203. Triticum aestivum L., nom. cons.Breeding. TC5. GP-413. Pedigree - Sunstar*2//Ll/Millewa. Resistance toBarley Yellow Dwarf Virus (BYDV). The genetic factor associated withreduced virus accumulation following infection was transferred from agroup 7 Thinopyrum (Agropyron) intermedium chromosome (7Ai-l) by cellculture induced recombination. Resistance is conferred by an independenttranslocation. The genetic factor responsible for BYDV resistance inthis germplasm has an additive effect and is inherited as a simpleMendelian factor.PI 578204. Triticum aestivum L., nom. cons.Breeding. TC6.

Received 03/23/1994.PI 578207. Triticum aestivum L., nom. cons.Genetic. Zl. GS-61. Pedigree - Zhong 7606*4/Zhong5. Disomic additionline (2n=44) to wheat derived by backcrossing from the partialamphiploid line called Zhong 5 (2n=56, wheat x Thinopyrum (Agropyron)intermedium). The Thinopyrum chromosome is a homoeologous group 2chromosome and confers resistance to Barley Yellow Dwarf Virus (BYDV).PI 578208. Triticum aestivum L., nom. cons.Genetic. Z2. GS-62. Pedigree - Wan 7107*3/Zhong5. Disomic addition line(2n=44) to wheat derived by backcrossing from the partial amphiploidline called Zhong 5 (2n=56, wheat x Thinopyrum (Agropyron) intermedium).The Thinopyrum chromosome is a homoeologous group 2 chromosome andconfers resistance to Barley Yellow Dwarf Virus (BYDV).162
