This is a summary of selected genetic research information (e.g., new factors; mapping; cloning) reported in this News Letter and in recent literature ("r" refers to numbered references in the Recent Maize Publications section). The Symbol Index refers by number to all current published research involving genetic materials; comments on this new aid would be welcome.

BS = Base Sequence; BSH = Broad Sense Heritability; gca, sca = general and specific combining ability; QTL = Quantitative Trait Loci; RM = Restriction Map; unc. = uncovered

* in symbols identifies loci needing allelism tests, documentation, or standardization of the symbol.

CHROMOSOME 1L

Mapping breakpoints of Reciprocal Translocation Stocks:

wxT1-9(8389) [1L.74,9L.13] : The 1L breakpoint for this commonly used translocation stock maps between bz2 and gs1. Data from 350 testcross progeny produced the following approximate recombination distances in centiMorgans:

bz2 - 4 - T - 8 - gs1 - 30 - bm2

T1-9(8389): The 1L breakpoint for the non-waxy version of this stock mapped to the same position.

T1-4g [1L.95,4L.35]: the 1L breakpoint maps distal to bm2. Data from 142 testcross progeny produced the following approximate distances:

bz2 - 22 - gs1 - 3 - bm2 - 7 - T

Note that recombination is reduced around the translocation breakpoint so that map distances are much less than in the standard map.

wxT1-9(035-10) [1L.89,9S.67]: The version of this stock which we got from the Maize Coop showed no linkage to bz2, gs1, or bm2. It may be misidentified as to breakpoint (Earl Patterson, personal communication).

CHROMOSOME 6S

McMullen and Louie (Mol. Plant Microbe Interactions 2:309-14, 1989) have mapped a major gene for resistance to maize dwarf mosaic virus strain A, Mdm1, to the interval between RFLP markers UMC85 and BNL6.29. Mead et al. in this volume of the newsletter have determined distances between the following probes: NPI7-6.3cM-UMC85-11.6cM-BNL7.28-2.1cM-BNL6.29.
