IV. NURSERY REPORTS FOR 1997

A. MASTER ENTRY LIST

Of the 166 noncheck, pure-line entries in the 1997 Quaker Nursery, 53 were continued from the 1996 Nursery, and 113 new pure line entries were added, 30 from Louisiana State Univ. through Texas A&M, 3 from Wisconsin and 80 from Minnesota, the latter selected primarily for rate-reducing crown rust resistance.

One entry position from each 20 pure-line entries was left vacant so that each collaborator could insert a local check of his/her own choice at planting. Thus, entries 1, 21, 41, 61, and 81 . . . 161 were local checks.

In the 1997 Quaker Nursery, the segregating populations were bulk F3 populations:

(a) 1997 entries 176-265: 90 Wisconsin bulk F3 populations

and

(b) 1997 entries 266-300: 35 Texas F3 populations

Itinerary comment: Because of the South American Conference and because of seed not getting to Brazil in time to plant, site visits were limited in 1997. Data for the 1997 South American nurseries are reported here although in all Brazilian sites, the Nursery was grown in 1998 along with the 1998 Nursery.

IV. D. CROWN RUST REACTION SUMMARIES

The purpose of these two summary tables is 1) to put all crown rust reactions from each appropriate test site (where crown rust was present) into a single table to enable easier line comparisons, and 2) to highlight those lines which had minimally acceptable levels of crown rust resistance at each of the test sites. The latter group (a subgroup of all 175 lines) represents the best candidates for more durable crown rust reactions. For now, we are forced to use geography to substitute for time as we attempt to identify more durable (longer lasting) resistance.
