The evaluation of yield and effective characteristics on yield of promising potato clones

Author(s): Samaneh Behjati*, Rajab Choukan, Hassan Hassanabadi and Babak Delkhosh

In order to evaluate the yield and yield components on promising potato clones a field experiment was conducted in Seed and Plant Improvement Institute of Karaj, Iran, in the summer of 2011. The study design was a randomized complete block with four replications. Treatments include 11 new potato clones with three witnesses called Agria, Lady Rosetta and Marfona. During growth and after harvest, average traits such as main stems per plant, number of tubers per plant, single tuber weight, and yield per plant were measured. Analysis of variance showed a treatment effect on all traits was significant at 1% level. Clone No. 397031-1, had the highest yield and Lady Rosetta variety had the lowest yield compared with other varieties. The lowest and highest average number of main stems per plant, related to Lady Rosetta and clone No. 397067-2. Lady Rosetta variety had the highest number of tube per plant and clone No. 397067-2 had the lowest number of tubers per plant. The lowest and highest average tuber weight per plant related to clone No. 397067-2 and Lady Rosetta variety respectively.
