Evaluate the representative CC in replicated multilocation trial for
morphological, agronomical and quality traits to identify parents for use.
Use data for making subgroups and developing mini core collection (MCC)
if the size of CC is too large.

Low and high temperature: In groundnut, tolerance to low
temperature at germination (12 o C) is an important trait.
Several accessions of the groundnut mini core with capacity
to germinate at lower temperature have been identifi ed,
many of them maturing and/or yielding similar to or better
than the best control (Upadhyaya et al., 2009d). Some of
the best performing low temperature tolerant accessions
for pod yield include ICGs 12625, 13284, 2039, 13513,
and 1824 in rainy season, ICGs 12553, 12625, 7898,
10595, 6148, 6022, 7013, 7884, 7905, and 4992 in post
rainy season, and ICGs 12625, 7898, 11130, 6148, 7013,
6022, 7905, 7884, and 4992 for both the seasons.
