Consequences of different levels of terminal stress tolerance on pearl millet panicle components and panicle harvest index (PNHI; Source: hypothetical data extracted from Bidinger, 2002).

Genotype level of tolerance	Panicle structural part (g)	Grains per panicle (no.)	Single grain mass (g)	Total grain mass (g)	Total panicle mass (g)	PNHI (%)
Non-stress conditions	5.0	1500	0.0100	15.0	20.0	75
Escape: early flowering	5.0	1500	0.0085	12.8	17.8	72
Tolerant	5.0	1350 (−10%)	0.0085 (−15%)	11.5	16.5	70
Intermediate	5.0	1200 (−20%)	0.0070 (−30%)	8.4	13.4	63
Susceptible	5.0	1200 (−20%)	0.0050 (−50%)	6.0	11.0	55
