Abstract:

The present investigation was conducted at Tirhut College of Agriculture (Bihar); without replication each plot measuring 1.5 x 1.0 meter in size and comprising 77 germplasm accessions. At 10 per cent selection intensity only 8 superior germplasm accessions including two check viz; C-29, UP-1, UP-3, C-1-92, C-6-92,White Gauria (LC), Jhingri and Shri Palavi (NC) were selected by combination of 10 quantitative traits with a certain range limits of each trait like plant size(cm), leaf length :breadth ratio, leaf type (width) (cm), petiole: leaf length ratio, petiole type, sheath type, corm size, cormel size and yield/plant. These accessions may be use full for further breeding programme. Petiole type exhibited significant and positive correlation with yield/plant (0.277*) while negative and highly significant correlation with sheath type (-0.353**). Sheath type had negative and significant correlation with yield/plant (-0.295*) while significant and positive correlation was observed with Corm size (0.234*). Corm size recorded positive and highly significant correlation with yield/plant (0.385**). Selection based on these traits may be effective for further improvement programme of taro. Most of the accessions collected from different regions were placed in all cluster except for cluster VII and IX in which only one accession was found in each cluster from different region. Due to geographical diversity they may be placed in different cluster and indicates that they are not genetically identical with each other.
