Chile, at the forefront of genetic incorporation

Renewal is the key in the nursery market, to respond to the demands of the fruit industry and to maintain its competitiveness. In these terms, the key aspects to which it is betting is to look for new varieties that respond to the needs of fruit load, size, appearance and time of harvest, among others. The objective is to incorporate through genetic improvement the characteristics that the market, the industry and the purchasing powers, and especially the consumers, demand.

According to José Ignacio Searle, manager of the Viveros Stoneflay business unit, the first thing to do is “define the focus of the project based on what one seeks or needs. There, a series of variables to be considered are opened and they must necessarily be included in the analysis, such as commercial, agronomic and logistic aspects".

Traveling blueberries

Marcela Zúñiga, executive director of Sunnyridge Nurseries, says that they have the license of new types of blueberries granted by the University of Florida. Among the more 15 varieties that this company manages stands emerald, along with snow chaser, scintilla, farthing and flicker.

Explain that emerald is the most productive par excellence. It adapts very well to different situations of the producers and generates large, firm fruit, good traveler and very well accepted by consumers.

The Snow Chaser variety is early par excellence. “It has behaved very well under plastic, which allows access to the window of high prices that occurs around October. It requires warm springs to express its full potential. It is earlier than emerald and very concentrated harvest".

For their part, scintilla and farthing taste good, are crunchy, firm, have very good productivity and are suitable for mechanized harvesting. “The farthing has stood out for its flavor, which has been very popular with consumers in Asia“. Meanwhile, flicker maintains the same characteristics as emerald, but offers a longer harvest window.

José Ignacio Searle reports that Viveros Stonefly manages two exclusive genetic programs in Chile, that of the University of Georgia and Fall Creek's own "breeding" in the US. He adds that work is being done at the crop level in both genetic programs to increase the varietal offer in the medium and long term in all segments of interest, from early to late varieties and new ones from the "rabbiteyes" group. All aggressive growth, high fruit load, size and firmness.

Multiple advances

In table grape, the Andes Nursery Association (ANA Chile) is using technology developed in Chile, such as INIA's PMG iniagrape-one cv (black, seedless, with extraordinary flavor and travel capacity), which is commercially planted in Chile and Peru. Luis Fernandez, executive director of ANA, explains that this year they will carry out the first plantations of stargrape2, seedless red grape, which is early, with good flavor and beautiful appearance.

In lemons, a variety that is generating great interest is the benjamin andes, from the eureka group, as it is more productive and with a higher percentage of harvest between February and May. Among the citrus fruits, clementine andes 1 cv clemenluz® also stands out, which, maintaining a very good quality, is harvested three weeks before clemenules.

The joint work of ANA and the University of Chile in the Australis Breeding has generated the series andes, which has already achieved four varieties of nectarines and a peach tree that stand out for their internal quality, appearance and especially traveling capacity. Finally, extreme® red, early nectarine, second half of December (excellent color, taste and travel capacity).

In apples, galaval is the new variety of the gala group, which is generating much attention for its extraordinary ability to color, and rosy glow is the novelty of the cripps pink band, which is also efficient in the generation of color and with a high percentage of production within the highest qualities.

Francisco García, general manager of Consorcio Viveros de Chile, highlights kiwi tsechelidis (megakiwi®), a protected variety that can only be found in Viveros Parlier and Vivero Tiempo Nuevo.

In walnut trees: “We have the last two clonal selections of paradox rootstocks from the University of California, Davis, of which we are exclusive graduates. These rootstocks have more vigor than the seed (the most used in Chile) and are a very good option for replanting conditions and soils with certain limitations".

In cherries, according to the specialized nurseries, the lead is carried by santina, which is self-fertile, early, good post-harvest and good production; lapins, self-fertile, very productive, good post-harvest, good taste; bing, very good post-harvest, good taste and very demanded in China; regina, late, very good post-harvest and good resistance to the rains (partidas), and kordia, late, resistant to rains, complement for the fertilization of regina.
