VARIETY DEVELOPMENT:

 and 1981. Dover AREC Research Report SV-1982-1. 6 pp.

 Marketable fruit yields for the 'Dover' cultivar were high both seasons.
 Breeding lines 77-163 and 77-169 had high yields the second season but
 less than 'Dover' the first season. There was some root knot nematode
 infestation in the two breeding lines the first season which may have
 reduced yields. Total marketable yields of 'Tufts' were less than 'Dover'
 both seasons and less than the two breeding lines the second season. For
 the two seasons, the January yield of 'Tufts' was less than the January
 yields of 'Dover' and breeding lines 77-163 and 77-169. January yields for
 'Pajaro' the second season were also fairly good. However, 'Dover' and the
 two breeding lines produced a greater percentage of their fruit before
 April than did all other cultivars.

 January marketable fruit yields were highest for 'Dover' and breeding lines
 77-163, 77-869, and 78-1268. The February yields of these same clones were
 also among the highest. Early (December and January) fruit production is
 important since fruit prices generally decline with time with the lowest
 prices coming in April. 'Tufts', 'Douglas', and 'Pajaro' yields for
 January and February were among the lowest of all hatones tested. March
 yields of 'Tufts', 'Douglas', and 'Pajaro' were among the highest.

 Dover ARC Research Report DOV-1983-2. 9 pp.

 January marketable fruit yields were highest for clones 80-456, 'Florida
 Belle', 80-1283, 77-163, 80-1232, 80-733, and 80-933. Clones 77-163, 80-733,
 80-933, and 80-1283 also gave high February yields. 'Douglas', 'Tufts',
 'Pajaro', 77-869, and 80-1340 yields were low in January and February.
 Since fruit prices generally decline with time, early yields (December and
 January) are important for a profitable season.
 Seasonal marketable yields were numerically highest with the clones 80-456,
 80-1232, 80-933, 80-733, 80-991, 77-198, 77-873, and 80-1283. Seasonal
 yields were numerically lowest with 'Douglas', and 'Tufts'. 'Douglas' had
 the lowest percentage of its fruit rated cull while clones 80-1283, 'Dover',
 80-852, and 77-873 had the greatest percent cull fruit. As noted in Table 2
 most cull fruit are harvested late in the season. The principal reason for
 cull fruit is small size. The large number of fruit on some clones during
 the latter part of the season plus the high temperatures often encountered
 at that time result in many small fruit. This is especially true of those
 fruit ripening last in a fruiting cycle.

 Dover ARC Research Report DOV-1984-3. 9 pp.

 December marketable fruit yields were confined to the day-neutral cultivars,
 'Fern' and 'Selva', and to three of the breeding lines. February yields were
 highest with clones 81-318, 81-2689, 80-866, 81-2553, and 'Dover'. Lowest
