Abstract:

An experiment with 39 F1C1 clonal progenies of potato was conducted under AICRP- potato in the Horticulture Research Farm of college of Agriculture, Indira Gandhi Krishi Vishwavidalaya, Raipur, (C.G.). Analysis of variance indicated existence of large variability among the clones for all the traits. 39 F1C1 clonal progenies were grouped into five distinct clusters depending upon the similarities of their D2 values. Cluster III had the highest number of progenies (11), followed by cluster IV (11), cluster I (10), cluster II (6) and cluster V (1). Tuber weight plant-1 (27.12) had the highest contribution towards the total divergence. The maximum intra cluster distance was recorded in cluster III, followed by cluster II, cluster IV and cluster I. The maximum inter-cluster distance was observed between cluster I and V. Genetically diverse clusters showing superior mean performance of genotypes namely, CIP 304012-2 of cluster I; CIP 304146-1 and Kufri Surya of cluster II; CIP 398203-3 of cluster III; CIP 398201-19 and CIP 398068-21 of cluster IV; Kufri Ashoka of cluster V. The progenies developed from the selected genotypes within the limits of compatibility of these clusters, may produce high magnitude of heterosis of desirable transgressive segregants, which would be rewarding in a breeding programme.
