Selection of Chilean potato clones for tuber yield, frying quality, plant vigor and vegetative cycle

ABSTRACT The objective of this study was to evaluate the yield potential, frying quality, plant vigor, and vegetative cycle of Chilean potato clones, aiming to identify those with potential to become new cultivars or to be used in breeding programs. The experiments were conducted in Pelotas-RS and Canoinhas-SC, Brazil, in spring 2017. A set of 37 advanced potato clones belonging to the Agricultural Research Institute of Chile (INIA) was compared to commercial cultivars Agata, Asterix and Atlantic. A randomized complete block design with three replications of two rows with 10 plants each was used. Tuber yield, frying quality, plant vigor and vegetative cycle traits were evaluated. The data were submitted to analysis of variance, test for grouping means, and the selection differential. In this set of clones there are some presenting superior quality in relation to marketable tuber yield and frying quality, but the vegetative cycle was not shorter nor plant vigor was lower. Clones CH 27 and CH 44 were the best for marketable tuber yield and frying quality at both locations.

ABSTRACT The demand for cultivars suitable for processing, especially as frozen French fries, is increasing in Brazil. The Canadian expertise is high regarding the development of cultivars with processing characteristics; however, the growing conditions in Canada are quite different from those observed in Brazil. Thus, the aim of this work was to evaluate the performance of Canadian potato clones for their tuber yield, frying quality, plant vigor, and plant cycle, as potential new cultivars or to be used as a new source of variability for crosses. The experiments were conducted in Pelotas-RS and Canoinhas-SC, Brazil, in spring 2017. A set of 12 advanced Canadian potato clones from the Centre de Recherche Les Buissons, QB, Canada, were compared to three control cultivars used for processing. A randomized complete block design with three replicates, with two rows of 20 plants each per plot was used. Tuber yield, frying quality, plant vigor, and plant cycle traits were evaluated. Data were submitted to analysis of variance, grouping of means, and selection gains. It is possible to select genotypes with higher tuber yield and better frying quality, but it is difficult to add also a short cycle. In an attempt to select productive genotypes, with good frying quality, a not so long cycle, and vigor at least equivalent to the control cultivars, clones 15 and 16 were the best at both sites.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

ABSTRACT The usual application of high 4-14-8 NPK fertilizer rates in the potato planting furrows, independently of the soil fertility or nutritional cultivar requirements, has become a paradigm in Brazil. However, the 4-14-8 NPK formula does not always meet the crop needs, and can unbalance the availability of nutrients in the soil. The objective of this study was to evaluate the tuber yield and economic results of ‘Atlantic’ potato as affected by rates of 4-14-8 and 6-30-6 NPK formulas applied in the planting furrows. The rates of both NPK formulas were calculated to reach P2O5 rates of 210, 420, and 630 kg ha-1. At each P2O5 rate, the 6-30-6 formula resulted in less 30% N and 65% K2O in the planting furrow compared to 4-14-8 formula. A randomized complete block design in a factorial scheme (2×3)+1, including an unfertilized furrow control, with three replications was used. Only the use of 6-30-6 formula increased the total tuber yield of ‘Atlantic’ potato. The marketable tuber yield reached higher levels (29.8 t ha-1) with higher P2O5 rate (440 kg ha-1) using the 6-30-6 than 4-14-8 formula. The fertilizer rates and formulas NPK did not affect specific gravity of marketable tubers. Therefore, the use of a fertilizer more concentrated in P2O5 that favors smaller contributions of N and K (as the 6-30-6 formula studied in this work) provides lower costs, and greater operational efficiency and profits in relation to the 4-14-8 formula traditionally used for the potato crop.

Abstract:The objective of this work was to characterize the performance of elite wheat genotypes from different Brazilian breeding programs for traits associated with grain yield and preharvest sprouting. The study was conducted in 2010 and 2011 in the municipality of Capão do Leão, in the state of Rio Grande do Sul, Brazil, in a randomized complete block design with three replicates. Thirty-three wheat genotypes were evaluated for traits related to preharvest sprouting and grain yield. The estimate of genetic distance was used to predict potential combinations for selection of plants with high grain yield and tolerance to preharvest sprouting. The combined analysis of sprouted grains and falling number shows that the TBIO Alvorada, TBIO Mestre, Frontana, Fundacep Raízes, Fundacep Cristalino, and BRS Guamirim genotypes are tolerant to preharvest sprouting. Combinations of TBIO Alvorada and TBIO Mestre with Fundacep Cristalino show high potential for recovering superior genotypes for high grain yield and tolerance to preharvest sprouting.

ABSTRACT Development of Brazilian potato cultivars adapted to different growing conditions, production systems and regions of the country is very important to increase the competitiveness of the national potato chain. In this sense, the objective of this work was to verify the performance of advanced potato clones for tuber yield traits, vine maturity and frying quality. An experiment was carried out in Pelotas-RS in spring, 2014. A set of nine advanced potato clones and two control cultivars were evaluated using a randomized complete block design with four replicates. Plots consisted of single rows of 20 plants spaced at 0.80 m between rows and 0.30 m between plants. The data of each trait were submitted to the deviance analysis, estimated the genetic values and selected the best genotypes using selection indices of the sum of ranks and the lowest distance from the ideotype. Clones F131-08-26 and F183-08-01, and the check ‘Asterix’ were distinguished for yield of marketable tubers. F183-08-01 and the control stood out for specific gravity and average tuber weight. Clone F161-07-02 ranked among the best for specific gravity, frying color and vine maturity. F97-07-04 and F183-08-01 and the check ‘Asterix’ were the best according to the selection indices, however, would result in losses in the frying color and vine maturity traits.

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.

An experiment was conducted to study characters associated with higher yield potential of potato genotypes at the Directorate of Agricultural Research, Tarahara, Nepal during two consecutive winter seasons of 2018 and 2019. A total of eleven potato genotypes (CIP 394600.52, CIP 396012.266, CIP 393371.159, PRP 266265.15, CIP 395443.103, CIP 393371.164, PRP 336769.1, PRP 136368.9, PRP 25861.11, CIP 377957.5 and PRP 225861.5) were evaluated in a Randomized Complete Block Design with four replications. Each treatment received a 7.2 m2 plot area with 60 cm row to row and 25 cm plant to plant spacing, accommodating 48 plants per plot. Cultural practices were done as per the recommendations and fungicide was not applied for late blight of potato (Phytophthora infestans) control. The observed data were subjected to variance, correlation and cluster analysis. Analysis of variance showed significant differences for some plant and tuber characteristics. From the pooled analysis of two years’ data, the genotype 'PRP 266265.15' was found to be a suitable genotype in plains due to its higher yield (21.91 t/ha) and other yield characteristics. The higher quantity of over seed-size and under seed-size tuber contributed to the highest tuber yield of PRP 266265.15. The weight (r = 0.928**) and number (r = 0.483**) of the over seed-size tuber had a positive significant correlation with tuber yield per hectare. Further research is needed to study yield stability of the genotype 'PRP 266265.15' in various locations with similar production environments.

ABSTRACT Potato genotypes were evaluated in their performance, according to the genotype values for tuber yield traits. The experiments were carried out in Canoinhas and Pelotas, Brazil, in spring 2014. Eleven advanced clones and two commercial cultivars (Agata and Asterix) (check cultivars) were evaluated. A randomized complete block design with four replicates was used. Plots were harvested 110 days after planting, and evaluated for tuber yield components. The data were submitted to joint deviance analyzes using the REML/BLUP method. Clones F102-22-07 and F32-02-06 stood out positively for tuber yield. F102-22-07 showed high marketable tuber yield and average tuber weight, while clone F32-02-06 exhibited high marketable and total tuber yield. The superiority of these advanced clones in relation to the check cultivars, suggests their potential to be evaluated in other environments, aiming their release as new cultivars.
