Host plant resistance to rust in sorghum

Four experiments were conducted to determine the stability of varietal resistance and dominance of rust reaction in F sub(1) hybrids under different genetic (plant pigment) and cytoplasmic backgrounds. All the tan pigmented varieties and hybrids were not resistant to rust. CSV-4 and SPV-312 were tan...

Zusammenfassung:	Four experiments were conducted to determine the stability of varietal resistance and dominance of rust reaction in F sub(1) hybrids under different genetic (plant pigment) and cytoplasmic backgrounds. All the tan pigmented varieties and hybrids were not resistant to rust. CSV-4 and SPV-312 were tan (T) parents highly resistant and stable in rust reaction over environments. Male sterile and B-lines were moderately susceptible. Purple (P) pigmented parents transmitted susceptibility as dominant character.
