Inheritance of Twisted Pods in Common Bean (Phaseolus vulgaris L.)

Inheritance of a twisted pod characteristic, in which bean pods develop with a twist that sometimes exceeds 360°, was studied in crosses between round-podded green bean cultivars. In crosses between `Oregon 91G' (normal) or `Oregon 54' (normal) and OSU 5256-1 (twisted), the F1 was normal. Segregation in F2 populations, tested over a 4-year period and including 4,995 plants, clearly fit a 3 normal: 1 twisted ratio. All plants of backcrosses of the F, to the normal parent were normal and backcrosses of the F1 to the twisted parent segregated 1 normal: 1 twisted. The ratios observed indicated that twisted pods are conditioned by a single recessive gene for which the symbol tw is proposed.

Induced Mutant

A mutation for blue (methyl-violet) flower color was induced by gamma irradiation of dry seed in common bean (Phaseolus vulgaris L.). Inheritance and allelism tests demonstrated that the mutation is controlled by a single recessive gene that is not allelic with Sal or V. The gene symbol blu is proposed for this mutant. Linkage was detected between blu and Fin, which controls the change from indeterminate to determinate plant habit. Three linkage estimates ranged from 19 to 35 cM, but the large variability (homogeneity x2 = 45.32) precludes making a conclusive combined estimate of linkage. The tentative combined estimate of linkage is 27 cM.

Gene Symbols

Dry seeds of common bean (Phaseolus vulgaris L.) were treated with 20 krad (1 rad = 0.01 Gy) of gamma rays to induce plant mutations to be used as genetic markers in mapping studies. Four leaf mutants are described and illustrated. Inheritance studies demonstrated that each is controlled by a single recessive gene. The proposed gene symbols are: cml for chlorotic moderately lanceolate leaf, lbd for leaf-bleaching dwarf, glb for glossy bronzing leaf, and 01 for overlapping leaflets. Linkage tests involving cml and nine previously reported marker mutants failed to detect any linkages.

The Cross

The development of genetic tester stocks in common bean (Phaseolus vulgaris L.) for the partly colored seedcoat patterns `bipunctata BC3 5-593' (t z bip) and `virgarcus BC3 5-593' (t z) was described. The inheritance of the bipunctata pattern was studied in the F2 from the crosses `bipunctata BC1 5-593' × 5-593 and `bipunctata BC2 5-593' × 5-593. The data supported the hypothesis that a single recessive gene (bip) converts virgarcus (t z Bip) to bipunctata (t z bip). The inheritance of bipunctata was also studied in the F2 from the cross `bipunctata BC3 5-593' × `virgarcus BC3 5-593'. The data supported the hypothesis of complete dominance of Bip over bip in a t z genetic background highly related to the recurrent parent 5-593, where only the parental phenotypes appear in the F2.

Selection Of

An abnormal pod condition, in which bean pods are twisted, sometimes as much as 360°, was discovered in a selection of OSU 5256, a Bush Lake breeding line. The amount of twisting of affected pods and the number of affected pods/plant are both variable. F2 progenies from crosses between twisted pod line 5256-1 and two normal bush Blue Lake cultivars segregate 3 normal:1 twisted, showing that the twisted mutant is controlled by a single recessive gene.

The Common

Dry seed of the common bean (Phaseolus vulgaris L.) breeding line S-593 was treated with 200 Gy of gamma radiation, and M2 seed was produced. The seed was planted at Prosser, Wash., and selection was made for plants with greatly reduced seed set. The inheritance of one of the selections for possible male sterility mutation was studied in F2, F3, and backcross generations. This character is controlled by a single recessive gene, for which the symbol ms-1 is proposed. Plants carrying ms-l/ms-1 produce well-filled pods after manual pollination with pollen from normal plants, but produce no seed when protected from insect pollination in greenhouse and field environments. Uses for this mutant are discussed.
