Flavonoid-deficient mutants in grass pea (Lathyrus sativus L.): genetic control, linkage relationships, and mapping with aconitase and S-nitrosoglutathione reductase isozyme loci.

Abstract excerpt

Two flavonoid-deficient mutants, designated as fldL-1 and fldL-2, were isolated in EMS-mutagenized (0.15%, 10 h) M(2) progeny of grass pea (Lathyrus sativus L.). Both the mutants contained total leaf flavonoid content only 20% of their mother varieties. Genetic analysis revealed monogenic recessive inheritance of the trait, controlled by two different nonallelic loci. The two mutants differed significantly in...
