Reciprocal effects in potato (Solanum tuberosum L.) x AndigenaTuberosum intergroup hybridization under shortdays

Published on

Six Tuberosum and five Andigena parents were used to
generate 23 Tuberosum × Andigena direct and 23 reciprocal
progenies. These progenies were evaluated for total yield,
marketable yield, tuber number, average tuber weight and
per cent tuber dry matter in second and third clonal
generations. Evaluation of progenies in field was done in
Randomized Complete Block Design with split plot taking
direction of cross (Andigena versus Tuberosum as female)
as sub-plot and parental combination as main-plot.
Significant variation was recorded in progenies for the
characters studied. Results revealed that that reciprocal
cross differences in inter group crosses were in general
not significant for all the characters. The lack of reciprocal
cross differences in short-day length environment in Indian
plains shows that crosses can be attempted in either
direction while breeding cultivars for Indian plains.
