Yield, frying quality, plant vigor, and maturity of potato clones

Abstract

The objective of this research was to evaluate advanced potato clones for tuber yield, frying quality, plant vigor, and maturity, grown from minituber seeds, and to assess correlations between these traits. Eight advanced potato clones of Embrapa Potato Breeding Program (F11-09-03, F05-11-03, F54-11-06, F141-11-01, C2718-12-09, C2718-24-09, C2743-09-09, and CL308) and three commercial cultivars (Agata, Asterix and BRSIPR Bel) were evaluated. Experiments were carried out in autumn 2017, in Canoinhas-SC and Pelotas-RS. A randomized complete block design with four replicates was used. We used tuber seeds type IV (minibubers). We evaluated plant vigor, maturity, yield and number of marketable tubers, yield and number of total tubers, average tuber weight, specific gravity, and frying color. Individual and joint variance analyses revealed significant differences (p <0.05) among genotypes for all traits at both locations. The GxE (genotype x environment) interaction was significant for all traits. For the two locations together, clones F05-11-03, C2718-12-09, C2718-24-09 and the control cultivar BRSIPR Bel showed higher marketable tuber yields. The first two clones also showed tubers with high average tuber weight. Clone F54-11-06 showed the later maturity at both locations. Regarding the frying quality characteristics, only clone F141-11-01 showed a pattern comparable to that of the control cultivar Asterix. Also, clones with higher plant vigor had higher tuber yield, but late maturity. Frying quality traits were not correlated between them and among other traits.

Effect of the plant growth-promoting bacteria strain Bacillus mojavensis I4 on potato growth, physiology, tuber yield and quality under salt stress conditions

“…Higher dry matter provides advantages of higher processing yield, less fat absorption, better texture without affecting the taste. On the other hand, low sugar contents prevent the darkening of the processed potato products, which compromises the appearance and avor of the fried product (Silva et al 2019;Kammoun et al 2022). Tubers obtained in this study from BmI4-treated plants showed the lowest reducing sugars and higher dry matter (19.5%) compared to tubers of non-inoculated plants under salt stress conditions (12.59%).…”

Determining Adaptability of Potato Genotypes in Mount Elgon Region of Uganda

“…Plant vigor is influenced by nutrient uptake and utilization by the different genotypes. Numerous studies have reported correlations of medium magnitude between plant vigor and plant size, tuber number and tuber yield, indicating that the more vigorous plants produce larger, higher number and higher yield of tubers [20,21,22]. According to Salas, [14], genotypes with weak plant vigor have few leaves and thin stems.…”

“…The season had sufficient rainfall to support proper plant growth. Differences in tuber size influence growth and processing qualities [21]. According to Tessema et al, [27], large tubers have more sprouts and produce more stems per plant.…”

Performance of tetraploid biofortified potato clones in Rwanda

“…The plant vigor is an important trait for farmers’ selection process of a good potato variety. In the study to determine the correlations between plant vigor and plant size, tuber number, and tuber yield, it was found that the more vigorous plants produce larger number and high tuber yield (Silva et al., 2019).
