Dominance degree of petiole length in sunflower line crosses

Dominance degree of petiole length in sunflower line crosses. Demurin Ya.N., N.N. Tolmachova. "Scientific Bulletin", VNIIMK, 2005, v. 1 (132). Inheritance of petiole length in Fj with dominance degree using was carried out. The different types of inheritance were observed in crosses of three short petiole lines SL2399-1, KG27 and K561-2 with wild type inbreds: dominant (SL2399-1), reces sive (KG27, K561-2).. Maternal effect was not observed in reciprocal crosses. Hybridiza tion of short petiole lines reveled the mutant progenies only. Hybridization of normal lines showed heterosis in 8 crosses from 13.
