Since the demand is for early-ripening, yellow-fleshed peaches, Alabama grow- ers must discard the white-fleshed va- rieties formerly grown for the early market. The variety situation based on the report of farmers in Chilton County, Alabama, February, 1951, changed considerably from 1946 to 1951 as giv- en in Table 2.2 TABLE 2.

Most of the varieties have been tested at Auburn, and many of the newer ones have been tested at the Chilton Area and North Alabama horticulture substations. Most of the newer varie- ties tested proved superior to older ones of the same ripening period. Recommended varieties for central and northern Alabama are given in Ta- ble 3. It will be noted that more than one variety is given for a specific ripen- ing period. Since there is a difference in the cold weather requirements of different varieties, it is desirable to plant varieties with high and low chill- ing requirements as insurance against variable weather in Alabama. No varieties ripening later than El- berta are generally recommended for planting in Alabama because of com- TABLE 3.

Grow- ers who have a good local market for late varieties, such as roadside stands, and who will follow a good spray pro- gram to control diseases and insects should plant a limited number of such varieties as Shipper's Late Red, Rio Oso Gem, and Afterglow. There has been considerable interest in peach growing on a limited scale in the southern half of Alabama. Va- rieties requiring short periods of cold weather to break their dormancy are needed for this area. Varieties with low chilling requirements recommended for planting south of Montgomery are given in Table 4. DESCRIPTION o4 VARIETIES Afterglow is a late variety, ripening nearly a week after Elberta. Its fruit is large, freestone, and has firm, yellow flesh. It has a medium to light blush. Afterglow trees are moderately vigor- ous and productive, with fairly tender flower buds. Although usually not as well-colored as Rio Oso Gem, After- glow is sometimes preferred to it be- cause of greater tree vigor and slightly greater flowerbud hardiness. Cardinal (USDA FV-101) is very early, ripening about 61/ weeks before Elberta. This variety produces medi- um, round, clingstone fruit that has a bright red blush over a yellow ground color (under color). The flesh is yel- low, firm but melting, of medium tex- ture, and has a good flavor. The trees are productive, but only moderately vigorous. Blossoms are self-fertile and medium in size. Coronet (USDA FV 126-79) is an early variety, ripening 2 or 3 days be- fore Dixigem. Fruit is medium and ovate with very light pubescence. The surface has an attractive bright red blush over yellow ground color. Its yellow flesh is firm but melting and smooth-textured, but tends to cling at the pit when not fully ripe. Flavor is good but mild. Trees are vigorous and productive, and about as susceptible to bacterial spot as Elberta. Blossoms are small-petaled and self-fertile. Dixigem is early, ripening 4 to 5 weeks before Elberta and about a week before Golden Jubilee. Fruits are me- dium-sized, light to medium red over about half the skin surface and have a bright yellow ground color. The flesh is yellow, usually free when ripe, firm and fine-textured. Dixigem is suggested as an early shipping variety and for local sale where an early yellow peach is needed. Dixired is very early, ripening 5 to 6 weeks before Elberta. Fruits are medium-sized with bright red skin. Flesh is yellow, clingstone, medium firm and melting. Dixired looks prom- ising for very early shipping or for local marketing where earliness is of prime importance and a clingstone va- riety is acceptable. Considerable acre- age of this variety has been planted in the Southeast. Elberta is a midseason variety, and by far the leading variety in the United States. Its fruits are large with red blush. Flesh is yellow, free, firm, and of fair to good quality. Elberta trees are productive, and its flower buds are tender to low temperature. Its popular- ity with growers is due to the large size, firmness, attractiveness, and ship- ping quality of its fruit, the vigor of the trees, and its suitability to many soil and climatic conditions. Although Elberta should still be considered the [3 ] principal commercial midseason vari- ety, midseason varieties superior to it in quality, hardiness, and skin color are being planted in numerous or- chards. Fairhaven is an early midseason va- riety, ripening after Golden Jubilee and about 3 weeks before Elberta. A yel- low, freestone peach, Fairhaven is good for freezing and canning, and for local marketing and commercial production. Halehaven ripens in midseason, about 2 weeks before Elberta. The fruits are large and round, and skin color is sometimes too dull. Flesh is yellow, free, and fairly firm for the season. Flower buds are fairly hardy, and the trees are vigorous and productive. Fruit often sets heavy, making detailed thin- ning necessary. Although Halehaven lacks the shipping qualities of Elberta, it has been one of the most outstanding varieties introduced in recent years for commercial planting. It may well be used for local markets and home plant- ings, also. Hiland (USDA FV 128-41) ripens 1 day earlier than Cardinal and 5 days ahead of Dixired. Fruit is clingstone, medium, and ovate, with very light pubescence; it is attractively colored with light red blush. Flesh is yellow, fairly firm, medium-textured and has good flavor. Trees are vigorous and productive. Blossoms are large-petaled and self-fertile. July Elberta is a midseason variety, ripening about 2 weeks before Elberta. Fruits are large, round and free, with fairly firm yellow flesh. Trees are pro- ductive and have short chilling require- ments. This is one of the best commer- cial varieties for its season at Auburn. Loring is midseason, ripening 1 week before Elberta. Fruits are medium to large, very attractive, and freestone with yellow flesh. Loring has not been widely tested, but is very promising in Alabama. Maygold (USDA FV 182-12) ripens 8 days ahead of Dixired. Its fruit is clingstone, medium and ovate, with very light pubescence; it is attractively colored with light red blush over yellow ground color. Flesh is yellow, firm but melting, medium-textured and has good flavor. Trees are vigorous and produc- tive, but subject to bacterial spot. Blos- soms are small-petaled and self-fertile. Chilling requirement is low enough for extreme southern Alabama. Newday is an early midseason vari- ety, ripening about 8 weeks before El- berta. Fruits are medium to large, with an attractive red blush. Flesh is yel- low and freestone, but lacks firmness for shipping. Plant for home use and local market. Redcap (USDA FV 121-58) ripens 1 or 2 days ahead of Dixired. Fruit is clingstone, medium, round, and has light pubescence - similar to Dixired. The surface is covered with a bright, attractive red blush. Flesh is yellow, firm but melting, medium-textured and has good flavor. Trees are moderately vigorous and productive with low chill- ing requirements. Blossoms are small- petaled and self-fertile. Plant in place of Dixired in southern Alabama, and with Dixired in central Alabama to avoid prolonged dormancy. Redhaven is early, ripening 4 to 5 weeks before Elberta. Fruits are small to medium and require early thinning to develop good size. Skin is bright red and attractive. Flesh is yellow and usually free when ripe. Redhaven peaches are excellent for canning and freezing. Flower buds are moderately hardy. Redskin ripens in midseason, about the same time as Elberta. Its fruits are large and round, and the skin is an attractive, almost solid, bright red. Flesh is yellow, free and firm. It is a good variety for freezing and canning, and looks promising as a commercial variety to replace Elberta, particularly because of color and quality of the fruit. Rio Oso Gem is late, ripening with Afterglow. It produces large fruit, with medium to bright blush. Flesh is yel- low, free, of good quality, and firm. [4] Trees are rather weak, moderately pro- ductive and susceptible to bacterial spot. Its flower buds are tender to low temperature. This variety is popular with many growers because of the fruit's size, firmness, attractiveness and time of ripening. Shipper's Late Red ripens 1 week af- ter Elberta. Fruit is large, with me- dium to bright red blush and freestone. The yellow flesh is firm and medium- textured with good quality. Trees are vigorous and productive. Southland is an early midseason va- riety, ripening 2 to 3 weeks before Elberta. It has fruit that is round, medium to large, and has yellow ground color with medium blush. Flesh is yel- low, free and firm. This variety has low chilling requirements. It is good for freezing and canning and is being planted extensively. Sunhigh ripens in early midseason. Its fruits are large, attractive and has light, solid red skin. Flesh is attractive, fine-textured, yellow, usually free and firm. The buds are fairly hardy to low winter temperature, but apparently tender to low temperature in early spring. Relatively short chilling is suf- ficient for Sunhigh. It is susceptible to bacterial spot. Its principal merits are firmness, size, and attractiveness of fruit. Triogem is early, ripening about 3 weeks before Elberta. Its fruit is me- dium-sized and has attractive shiny color. Flesh is yellow, fine-textured, usually free, and firm. Flower buds are tender, and fruits may be small unless thinned well and early. Triogem gives good production. CHILLING REQUIREMENTS aud PROLONGED DORMANCY Peach trees go into dormancy or be- gin their rest period in late fall. Enough cold weather is needed to break their rest period before February 15 for normal growth and blossoms the fol- lowing spring. The amount of chill- ing required depends on the variety. The number of hours below 450 F. to break the rest period of flower and leaf buds has been determined by Wein- berger 3 at the U.S.D.A. Horticultural Field Laboratory, Fort Valley, Georgia. This information for the varieties rec- ommended for Alabama is given in Table 5. When temperatures are abnormally high during the winter, peach trees do not bloom and fruit normally in early spring. This condition is called pro- longed dormancy. Such was the case following the warm winters in central Alabama during 1948-49 and 1949-50. Observations were made on 68 peach varieties in the spring of 1950 to de- termine their growth and fruiting re- sponse to the mild winter. The May- flower variety, which requires 1,150 hours chilling for flower buds, was just beginning to bloom and had no foliage on May 4. As a rule, this variety at Auburn, Alabama, ripens TABLE 5.

The Jewel variety, which requires little chilling, bloomed January 15. The fruit was killed by late spring frosts, but the tree was in normal foliage on May 4. Varieties with low chilling requirements (750 to 850 hours) had fruit ranging from 1/4 to 1 /4inches in diameter and from one- half to three-fourths their normal foli- age on May 4. Among these varieties were Afterglow, Dixigem, Elberta, Fairhaven, Halehaven, July Elberta, Loring, Newday, Redhaven, Redskin, Rio Oso Gem, Shipper's Late Red, Southland, Sunhigh, and Triogem.
