Flavonoid-Deficient Mutants in Grass Pea (Lathyrus sativus L.): Genetic Control, Linkage Relationships, and Mapping with Aconitase and S-Nitrosoglutathione Reductase Isozyme Loci

Table 2

Single locus segregation of fld 1 and fld 2 mutations, two aconitase (Aco1 & 2), and S-nitrosoglutathione reductase 2 (Gsnor 2) isozyme loci in F2 and backcross (BC1) populations of different intercrosses among four parents in Lathyrus sativus L. aFF-Homozygote of fast alleles, SS-Homozygote of slow allele, FS-Heterozygotes. *, **, and *** consistent with 1 : 2 : 1, 1 : 1, and 3 : 1 ratios, respectively, at 5% level of significance, ++parent/s showing slow allozyme used in testcross with F1 and pooled data of several crosses presented.
