Cytoplasmic genome of Indian potato varieties and breeding lines vis a vis prospects in potato breeding

Lutein and zeaxanthin are becoming established as carotenoids beneficial for protection against common age-associated eye diseases. Thus, 15 potato (Solanum tuberosum subsp. tuberosum L.) breeding lines, cultivars Atlantic, Spunta, and Yukon Gold; and orange flesh OR-4 were surveyed for carotenoid profiles. Seven carotenoids, including violaxanthin, neoaxanthin, antheraxanthin, lutein, zeaxanthin, β-cryptoaxanthin, and β-carotene, were identified in the 19 genotypes. Violaxanthin and lutein were the prominent carotenoids detected in all genotypes studied. Neoaxanthin and antheraxanthin were found in 26% and 63% of the genotypes, respectively. β-Cryptoaxanthin, zeaxanthin, and β-carotene were found in only 5%, 10%, and 16% of the genotypes, respectively. Lutein varied from 19.8 to 119.0 μg·100 g-1 fresh weight across the 15 white- or yellow-flesh breeding lines. In contrast, zeaxanthin was detected at a low level in only one breeding line and at high level in OR-4. The three cultivars had profiles typical of yellow-flesh potatoes `Spunta' and `Yukon Gold'; while `Atlantic' had a typical white-flesh profile and a trace of zeaxanthin. The carotenoid baseline data established in this study provide information for activities to enhance potato for lutein and zeaxanthin.

Relevance. Potato ladybug is a polyphagous pest. Its distributed throughout the Far East, in India, Korea, Japan and the countries of South America. Most affected by it are potatoes, tomatoes, eggplant, zucchini, peppers, cucumbers, pumpkin, melon, beans. Leaving the veins intact pest eats the soft tissue of the leaf. Such leaves die quickly. Potato ladybug is a carrier of some diseases of potato and it also causes damage to plants. But insecticides pollute products and sustainable insect populations. The use of varieties with high resistance to pest damage eliminates the need for mass application of insecticides.Methods. The data on a preliminary assessment of potato varieties of domestic and foreign selection for resistance to a twenty-eight-point potato ladybug Henosepilachna vigintiomaculata Motch. (Fabricius, 1775) in the Primorye Territory. This work aim work was a preliminary assessment of the traditional potato breeding resistance factors to pest damage. The experiment out using generally accepted methods for the study and evaluation of potato varieties for pests with minor modifications was carried.Results. As a study result it was found that Belmonda, Labella, Red Lady, Queen Anna, Lilly, Sante varieties were the least suitable for passing the stages of ontogenesis and nutritional nutrition of the pest. The most tolerant to the pest – varieties Smak, Casachok, Yantar. The maximum mortality of potato ladybug larvae was observed in varieties Belmonda, Dachny, Augustin, Yubilyar, Labella, Sante, Koroleva Anna, Laperla in laboratory experiment. Minimum on varieties Smak, Casachok, Yantar, Red Lady. The data indicate the manifestation of an antibiotic barrier in potatoes, which must be confirmed by a field experiment.

In-row spacing studies have been conducted with `Beauregard!, `Hernandez' and some promising seedlings in the LSU Agricultural Center sweet potato breeding program. May, June and early July plantings are evaluated on 1 m rows with in-row spacings of 23, 30, 38, and 46 cm. With the variety `Beauregard' early May plantings (1-15th) yields of U.S. No.1 grade roots are higher at the 30 cm spacing. From mid-May to June 20th higher yields of No. 1's are produced at a 23 cm spacing. Higher yields are obtained in the late June-early July plantings at the 30 cm spacing. Highest yields overall are produced in late May-early June plantings with `Beauregard'. With the `Hernandez' variety the highest yield of U.S. No.1 grade roots have been produced at a 38 cm in-row spacing during all three planting seasons, with the highest yields overall being produced in the May plantings. Days to maturity are reduced in early `Hernandez' plantings. Results of limited in-row plant spacing with the seedling `LU7-59' are identical to the `Beauregard' variety.

In Vitro Preservation

At EVIKA, we have been preserving potato varieties, breeding lines and land-races in vitro as meristem plants for more than 30 years. Various experiments have been conducted to determine the effects of medium components, growth conditions and other factors on regeneration and the sub-culturing interval of in vitro plants. Based on these experiments, the optimal preservation medium and long-term preservation conditions in vitro for many varieties have been developed. Every 3.0-3.5 months, the potato plants regenerated from meristems are transferred onto growth-regulator-free propagation medium. At present, there are 454 potato varieties, breeding materials, land-races and 1026 meristem clones in our gene bank. The interest in varieties as genetic resources and in those with coloured flesh tubers is increasing. In EVIKA’s test field we have been testing meristem clones of variety ‘Blue Congo’. We have demonstrated the use of that variety for making salads; baked, boiled, mashed potato and even for French fries. In addition, the use of the genetic resources was started in a farm, where. 2000 kg seed tubers were produced from 4580 meristem plants of variety ‘Väike verev’ in 2012. The main interests are: dark yellow flesh, content of antioxidants and use as a source for functional diet.
