Screening and Evaluation of Initial Clonal Generations of Potato Hybrids for Yield and Yield Attributing Characters

A field experiment was conducted during Rabi 2015-16 and 2016-17 at ICAR-Central Potato Research Station, Patna Bihar. In this experiment F1 with initial clonal generations viz F1C1, F1C2 and F1C3 were evaluated. The screening and selection of these generations were done in randomized block design for the character like early bulking, tuber size, tuber shape, depth of eye, tuber colour and resistance to late blight of potato etc. A total of 12,360 True Potato Seeds of 17 successful crosses and 7,322 True Potato Seeds of 23 successful crosses were sown and seedlings were transplanted, out of these 610 and 187 clones were selected during 2015-16 and 2016-17 respectively. Large number of potato cultures were planted for further evaluation in next generations. In F1C3 the cultures were planted along with more than six check varieties of potato. Cultures were evaluated and selected considering total tuber yield, shape, colour and disease reactions for further evaluation in PYT.
