DIVERGENCE AND CLASSIFICATION ON OF DWARF AND NON-DWARF PEARL MILLET ACCESSIONS

Published on

To Identify parenti for crossing, the dlvenlty In a sample of dwarf and non-dwarf
Inbred lines, using 11 morphological traits was studied In summer season 1994 (El)
IDd rainy Muon 19M (EZ) at ICRISAT Asia Center, Patancheru, india. Significant
dlvenlty WU ObMrved In this Mt of 10 Inbred lines and five control entries.
Inter-eluster and lntra-cluster dlstmces were calculated using Mahalanobls 02 statistic.
TheM 15 ace_OBI were grouped Into 4 clusten In El and E2, as well as across
(pooled over) environments. The grouping was fairly consistent and largely
Independent of environmental Influence. The traits that mainly contributed to
groupInss were time to 50% stigma emergence, panicle length, effective tIllen, leaf
blade width and 1,000 BraIn mus. The set of Inbreds ICMP 85410, ICMP 91205,
ICMP 83503 and ICMP 89024 were selected for Intercrosslng since those fell Into
different groupe.
