“…According to Silva et al (2018b), traits related to the plant vegetative growth, such as stem number, stem size and plant vigor are related to the index of vegetative area available for photosynthesis. Some studies reported direct relationship of these traits with tuber yield, such as the positive relationship between plant height and tuber yield (Khayatnezhad et al, 2011;Arslan, 2007;Fekadu et al, 2013), and plant vigor with tuber yield (Silva et al, 2007;Pereira et al, 2017).…”

Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 crop season. A randomized complete block experimental design with three replicates was used. Traits related to different plant parts of clones F183-08-01 and F50-08-01 and the cv. Asterix were evaluated as a function of time and, at the end of the cycle, for tuber yield. The two clones were found to have high tuber yields, but later development than 'Asterix'; consequently, its management must be adapted to this trait. Leaf mass, leaf number, leaf area index and root mass plus stems were correlated with each other, and leaf area index, leaf number and leaf mass can be quantified through only one of these traits, due to the high correlation between them. There were also positive and significant correlations between the height of the tallest stem and the root plus stem mass and the tuber mass, indicating that more vigorous plants have higher tuber yield.

Potato development, especially processing varieties, is constrained by the availability of seeds. Acceleration of seed supply can be done by planting apical rooted cuttings directly in the field to obtain seeds equivalent to extension seeds class. Field activity has been carried out in Brebes Regency, Central Java, in 2021, to study the opportunities for using apical rooted cuttings in the potato seed production. Apical rooted cuttings from seven potato varieties for processing purposes (i.e. AR 08, Spudy, Ventury Agrihorti, Golden Agrihorti, Medians, and Atlantik M) were transplanted in a completely randomized design with 4 replications. Plant growth and tuber production characters were influenced by genotypic factor, indicated by the variation of those characters between varieties. The tuber number per plant ranged from 8.53 (Medians) to 22.80 (Spudy). Meanwhile, the tuber weight per plant was between 215.13 g (Golden Agrihorti) to 702.67 g (Spudy). In this study, Spudy showed the highest growth performance and tuber production compared to the other six varieties. In general, plants grown from apical rooted cuttings produced tuber which is appropriate for seed purposes. It is hoped that the apical rooted cuttings can support the sustainability of potato production, and furthermore, support the domestic potato-based industry.

“…Variation in plant vigor among the genotypes is attributed to both genotype and environmental factors [19,20]. Plant vigor is influenced by nutrient uptake and utilization by the different genotypes.…”

Potato (Solanum tuberosum L.) in Uganda is mainly produced in the highland areas of Kabale and Kisoro in south western and Bugisu and Sebei areas on the slopes of Mt. Elgon in the eastern part of the country. However, the yields have continuously reduced due to lack of suitable high yielding and disease resistant varieties. The purpose of this study was to identify high yielding disease resistant potato genotypes adapted to Mt. Elgon region. Eight CIP potato clones were evaluated alongside ten commonly grown Ugandan varieties in RCBD for two seasons at Buginyanya station, Bulambuli District. Results showed significant differences (P<0.05) in tuber size, tuber uniformity, marketable tuber yield and the total tuber yield among genotypes. Potato clones 392797.22 and 398208.29 produced significantly (P<0.001) higher tuber yield 44.8 t/ha and 39 t/ha respectively compared to the local check Cruza with 34.5 t/ha. rAUDPC for LB showed significant differences (P<0.001) among genotypes in both seasons. The most resistant genotypes were Kinigi and clone 399985.39 with rAUDPC of 0.0135 and 0.025 respectively whereas Bumbamagara (0.413) and 396036.201 (0.392) were the most susceptible. 396036.201(0.051) and Kinigi were the most resistant genotypes for bacterial wilt while Shangi (0.66) and Cruza (0.46) were the most susceptible to BW. Generally, genotypes 392797.22 and 398208.29 were the highest yielding and disease resistant hence recommended for release as commercial varieties.
