Abstract

To create genetic variations in potato during four years of study (2007-11) and use than in breeding programs, some 105 HYBRIDs were selected from cresses of Agria, Savalan, Boren, Kennebek and Ceaser cultivars as HYBRIDs parents, and planted in augmented design at the Agricultural and Natural Resources Research Station of Ardabil during 2010-2011. The marketable tuber yields produced by the parents and HYBRIDs were 42-52 t.ha-1 and 10.4-138.8 t.ha-1, respectively. The marketable tuber yields of HYBRIDs exhibited 23.81% over dominance, 52.38% incomplete dominance, 13.33% reduction dominance and 10.48% interval dominance. Almost 24% of all HYBRIDs selected produced higher marketable tuber yield than their parents. HETEROSIS for marketable tuber yield was found to be 58%. Based on the traits considered like marketable tuber yield, tuber uniformity, shallow eye depth, short stolon and yellow flesh and skin color, HETEROSIS and DOMINANCE DEGREEs some 28 HYBRIDs were selected. Among HYBRIDs selected, 14 belonged to ♂ Ceaser × ♀Savalan cross (021, 022, 023, 025, 026, 049, 057, 081, 087, 088, 095, 098, 0104 and 0105), four to ♂ Savalan × ♀ Agria cross (0500, 0502, 0503 0508), five to ♂ Ceaser × ♀ Agria cross (0611, 0613, 0616, 0618 and 0623) with early to mid-early maturity group, one to ♂ Boren × ♀ Savalan cross (0205), two to ♂ Savalan × ♀Ceaser cross (0300 and 0303) and two to ♂ Ceaser × ♀ Kennebek cross (0401 and 0403) with mid-late maturity group.
