SILVA, Giovani O da et al. Agronomic performance of elite potato clones. Hortic. Bras. [online]. 2012, vol.30, n.3, pp.557-560. ISSN 0102-0536.  https://doi.org/10.1590/S0102-05362012000300034.

The aim of this work was to verify the growth cycle, yield components and specific gravity of advanced potato clones as compared to the main varieties grown in Brazil. The experiment was carried on at the Embrapa Clima Temperado experimental field, in Pelotas, Rio Grande do Sul state, Brazil. Eight advanced potato clones developed by the Embrapa Potato Breeding Program, and two commercial cultivars were evaluated in the autumn season of 2011. A randomized complete block design with four replications was used, the plots being constituted by a line of 20 plants. Growth cycle was assessed 95 days after planting. Plants of each plot were harvested at 110 days, followed by evaluation of yield components and specific gravity. After checking for normality of error distribution, the data were submitted to analysis of variance and to means grouping by the Scott & Knott test. CL02-05, CL69-05, CL27-05 and 2197-15 clones showed higher commercial tuber number, percentage of commercial tubers and average tuber weight than the check varieties. CL02-05 clone showed, besides, the highest yield potential of commercial tubers of all four clones. CL69-05 and 2197-15 presented specific gravity and growth cycle similar to Asterix, but had higher yield potential and larger tuber size than it.
