V. Smith, Director 1952, 12 USDA releases were planted for evaluation, 10 from Fort Valley, and 2 from Beltsville, Maryland. A new va- riety block was set the winter of 1961 at Auburn with new varieties that have been introduced by state experiment sta- tions, private breeders, and the USDA. Several of these new varieties have indi- cated a low-chilling requirement for breaking dormancy. Peach variety testing was begun at the Wiregrass Substation, Headland, in 1954 to evaluate adaptability of low- chilling varieties, including Hiland, Southland, Newday, Maygold, Redskin, and Redcap. Additional low-chilling se- lections were added in 1957 and 1961. Testing low-chilling varieties was be- gun at the Gulf Coast Substation, Fair- hope, in 1961. This area is on the East shore of Mobile Bay. VARIETY RECOMMENDATION Many varieties adapted for commer- cial plantings are satisfactory for local or home use. Since many have been named and tested, only those that have exhibited good commercial qualities are discussed. Varieties recommended for commer- cial plantings are listed in Table 1. These varieties have performed well in trial plantings and many are widely planted for commercial production in the Chilton County and Blount County peach areas. VARIETY DESCRIPTION Springtime, (Unnamed Seedling of Luken's Honey X July Elberta) x Robin, is an early maturing, low-chilling white fleshed peach; this peach has per- formed well in the Chilton area, ripen- ing 8 weeks before Elberta and is de- sirable for limited plantings as an early local or roadside market peach. Spring- time is small, round, juicy, deep red skin, and ripens May 14 to 20. Its qual- ity is somewhat better than Mayflower. Springtime is highly susceptible to brown rot and has a chilling requirement of about 650 hours. TABLE 1.

[2] Hiland, Southland X (Hiley X Hale- haven), was developed by the USDA Field Station at Fort Valley and intro- duced commercially in 1952. Fruit ripens 61/ weeks earlier than Elberta and 4 to 5 days earlier than Dixired. It is me- dium in size, yellow flesh, clingstone, fairly well colored and juicy, and is fairly firm at shipping ripe maturity, but tends toward excessive split pits. Trees are very productive, vigorous, with large blossoms. Chilling requirement for Hi- land is about 750 hours. Cardinal, Halehaven X selfed, was in- troduced by the USDA Field Station, Fort Valley in 1951. Cardinal ripens 61/2 weeks before Elberta and about 4 days before Dixired. Fruit is yellow fleshed, small, clingstone, well colored, and is fairly firm at shipping maturity. Trees are productive and moderately vigorous. Chilling requirement is about 900 hours. Cardinal is recommended for planting with Hiland. In mild winters Cardinal may exhibit prolonged dormancy since it has a higher chilling requirement than Hiland. Redcap, Southland X Dixired, was de- veloped by the USDA Field Station, Fort Valley and introduced commer- cially in 1952. Redcap ripens approxi- mately 6 weeks before Elberta and nor- mally 1 or 2 days before Dixired. Fruit is very similar to Dixired, yellow flesh, round, clingstone, medium size, well colored, and firm at shipping maturity. Redcap has good quality and requires approximately 750 hours chilling. Dixired, Halehaven X selfed, was named and introduced in 1945 by the USDA Field Station, Fort Valley. Dixi- red is the most widely planted early maturing peach. Shipping maturity is 6 weeks before Elberta. Trees are vig- orous, productive, and fruits tend to be small in some years unless thinned heavily. Very often this variety will not average 2 inches in diameter. Fruit is well colored, firm, yellow fleshed, cling- stone, and good quality. Chilling re- quirement is about 900 hours. Dixired is recommended for planting with Red- cap to offset any prolonged dormancy that Dixired might exhibit in mild winters. Coronet, (Halehaven X selfed) X Dixi- gem, was introduced commercially in 1953 from Fort Valley by the USDA Field Station. Fruit ripens 5 weeks be- fore Elberta, is well colored, ovate, med- ium size, mild flavored, yellow fleshed, smooth textured, and firm at shipping maturity. Flesh tends to cling to pit when not fully ripe but is semi-freestone when soft ripe. Trees are productive, vigorous, but susceptible to bacterial leaf spot. Blossoms are small and tend to open early. Chilling requirement is about 800 hours. Coronet is recom- mended as an early-midseason peach to replace Dixigem. Redhaven, Halehaven X Kalhaven, was introduced by Michigan State Uni- versity at South Haven, Michigan. Fruit ripens 4 weeks before Elberta and 1 week later than Coronet, yellow flesh, semi-cling at shipping maturity, skin color not as good as Dixired, firm flesh, and good quality. In some years fruit will develop a rough suture under Ala- bama conditions. Trees are productive, vigorous, and need considerable thinning to size properly. Chilling requirement is about 950 hours. Redhaven is recom- mended for the 4 weeks before Elberta season. Ranger, Raritan Rose X selfed, was introduced in 1952 by the USDA Field Station, Beltsville. Fruit ripens 3 to 31/2 weeks before Elberta, yellow flesh, large, good color, firm, ovate, nearly a free- stone at shipping maturity, and has good quality. The fruit ripens uniformly and can be harvested in three pickings. Trees are productive and vigorous. This variety has exhibited high resistance to bacterial leaf spot in Chilton County. Poorly pruned trees tend to develop weak crotches. Ranger is recommended for the same season as Keystone, and it [ 3 ] has a chilling requirement of about 950 hours. Keystone, Newday X Southland, was introduced by the USDA Field Station, Fort Valley, in 1954. Fruit is large, round, light colored, juicy, with good quality, ripening 3 weeks before Elberta. Flesh is yellow, smooth textured, and nearly freestone at shipping maturity. Trees are productive and vigorous, but do not produce heavy crops until the 4th or 5th year. Blossoms are small and tend not to set heavy crops under high nitrogen conditions. Keystone is recom- mended for a midseason peach. It has a chilling requirement of about 750 hours. Southland, Halehaven X selfed, was introduced in 1946 by the USDA Field Station, Fort Valley. Fruit is large, well colored, ripens 2 weeks before Elberta, freestone, yellow flesh, and has good quality at shipping maturity. Objections to Southland are its susceptibility to bac- terial leaf spot and unproductiveness as young trees. Older trees are vigorous, productive, and have large showy petals. Southland has a chilling requirement of about 750 hours. Redglobe, (Admiral Dewey X St. John) X Fireglow, was introduced by the USDA Field Station, Beltsville, in 1954. Fruit ripens 2 weeks before Elberta in Chilton County, is yellow fleshed, well colored, round, firm, good quality, and remains on the tree at shipping maturity. Redglobe is a freestone and ships well. Trees are moderately resistant to bac- terial leaf spot. To size properly Red- globe must be thinned. Trial plantings are recommended for partial replace- ment of Halehaven and Southland. Chill- ing requirement is about 900 hours. Loring, Frank X Halehaven, was in- troduced by the Missouri Agricultural Experiment Station in 1946. Fruit ripens 1 to 11/2 weeks before Elberta, is yellow fleshed, freestone, firm, good quality and color, medium size, and handles well for commercial packing. Trees are vigorous and productive. Loring has a chilling requirement of about 750 hours and is recommended for the season between Southland and Elberta. Blake, J. H. Hale X Primrose, was in- troduced in 1953 by the New Jersey Agricultural Experiment Station. Fruit ripens one-half week before Elberta, is freestone, yellow fleshed, has good color, quality, and firm flesh at shipping ma- turity. Trees are moderately vigorous and tend to set light crops in most years. Chilling requirement is about 750 hours. Blake is recommended for commercial planting to precede Elberta by 3 to 4 days. Redskin, J. H. Hale X Elberta, was released by the Maryland Agricultural Experiment Station in 1944. Fruit ripens at the same time as Elberta, has yellow flesh, good color, and quality, is freestone, firm, and large when properly thinned. In some years a rough suture will de- velop. Trees are moderately vigorous and productive. Blossoms tend to set fruit every year. Redskin is moderately resistant to bacterial leaf spot. Chilling is about 750 hours. Elberta, unknown, was discovered and introduced by Samuel H. Rumph, Mar- shallville, Georgia, in 1870. Fruit ripens normally about July 19 in Chilton County, is freestone, yellow fleshed, has excellent quality, and ships very well. Elberta has rather poor skin color and is susceptible to bacterial leaf spot. Trees are vigorous and productive. Regular Elberta is recommended for its popu- larity and good quality. Rio-Oso-Gem, unknown, was intro- duced in 1933 by W. F. Yerkers, Rio- Oso, California. Fruit ripens 1 week after Elberta, is yellow fleshed, has ex- cellent quality, round, firm, well colored, and good size when thinned properly. Chilling requirement is about 850 hours. Trees are vigorous, and productive. Rio- Oso-Gem is recommended for late mar- ket. [ 4] VARIETIES FOR SOUTHERN ALABAMA Varieties Springtime, Hiland, Redcap, Southland, Loring, and Redskin have low chilling requirements and commer- cial qualities. These varieties are also recommended for the southern half of Alabama or that portion of the State that lies south of Montgomery. Ripening dates should be a few days earlier in the extreme south portion. This early ripen- ing provides an early peach for market. In some years, particularly those that are mild, it can be expected that these va- rieties may not perform as described. Therefore, they are recommended as trial plantings rather than for extensive commercial operation. TABLE 2.
