Abstract

Potato is an important crop in Turkey. Along with modern cultivars, there are some potato landrace cultivars grown mainly for their superior taste. ‘Baçiftlik Beyazı’ is such a landrace cultivar grown in the Mid-Black Sea region of Turkey and used as baked potato. Since this cultivar is not registered, certified seed is not available. Therefore, tuber production suffers from serious yield and quality losses mainly due to viral diseases. The aim of the present study was to determine a main genotype and different genotypes within the cultivar using 16 SSR markers. SSR analyses were conducted over 191 ‘Baçiftlik Beyazi’ plants. Nine of the 16 SSR markers were polymorphic. The data showed that landrace cultivar ‘Baçiftlik Beyazi’ consisted of 23 different genotypes. The same marker profile was present in 150 of the 191 plants. SSR analyses conducted on some modern and landrace cultivars grown in the region showed that the different genotypes were not the remnants of the previous years’ potato crop. This variation could be directly used in potato breeding. SSR marker data also indicated that three local cultivars with different names were actually the same.

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
