A set of 219 DNA clones derived from mungbean (Vigna radiata), cowpea (V. unguiculata), common bean (Phaseolus vulgaris), and soybean (Glycine max) were used to generate comparative linkage maps among mungbean, common bean, and soybean. The maps allowed an assessment of linkage conservation and collinearity among the three genomes. Mungbean and common bean, both of the subtribe Phaseolinae, exhibited a high degree of linkage conservation and preservation of marker order. Most linkage groups of mungbean consisted of only one or two linkage blocks from common bean (and vice versa). The situation was significantly different with soybean, a member of the subtribe Glycininae. Mungbean and common bean linkage groups were generally mosaics of short soybean linkage blocks, each only a few centimorgans in length. These results suggest that it would be fruitful to join maps of mungbean and common bean, while knowledge of conserved genomic blocks would be useful in increasing marker density in specific genomic regions for all three genera. These comparative maps may also contribute to enhanced understanding of legume evolution.

There is an error in the third column of Table 2. It should read r 2 (p-value) instead of r (p-value). Volume 34, no. 2, p. 560. The minutes of the annual meeting of Division C-5, Turfgrass Science, was inadvertantly truncated. It is printed in its entirety below. C015 TURFGRASS SCIENCE, DIV. C-5 The C-5 business meeting was called to order by M. Petrovic at 4:15 p.m. on 9 Nov. 1993. There were 106 in attendance. The agenda was distributed and approved. The minutes of the 1992 meeting were approved as distributed. Copies of the attendance roster were circulated. Several people in attendance asked how they could obtain a copy of the C-5 Business Meeting Attendance Roster. M. Kenna, of the United States Golf Association, volunteered to mail copies of the roster to all individuals listed on the roster. C. Throssell and future secretaries, will provide an updated roster to M. Kenna or other USGA representatives following the C-5 annual meeting for distribution. NTEP Presentation, K. Morris and R. Shearman K. Morris presented a $3000 contribution to V. Cardwell, CSSA President, to support the C-5 Symposia. V. Cardwell thanked K. Morris and NTEP for support of C-5 and the CSSA. V. Cardwell also thanked C-5 members for their contribution of time, interest, and expertise to C-5 and CSSA. He stated that C-5 was often used as a model division for other CSSA divisions. R. Shearman updated attendees on activities of NTEP. NTEP is alive and well. They are currently in the process of determining direction for the program. K. Morris and R. Shearman are planning visits to sites of official tests when feasible. They will also attend regional research meetings on an annual basis.
