Combining ability for PNHI, yield and yield components of restorer and maintainer lines selected for high (nine lines) and low (nine lines) combining ability for PNHI, in test cross nurseries grown under terminal drought stress at ICRISAT-Patancheru.

	PNHI (%)	Grain yield (g m−2)	Grain no (103 m−2)	Seed mass (mg seed−1)
RESTORER LINES
High PNHI selections	64.8	218	31.1	6.86
Low PNHI selections	59.8	192	29.5	6.38
SED	0.4	2.7	3.7	0.69
MAINTAINER LINES
High PNHI selections	63.6	189	29.7	6.31
Low PNHI selections	60.4	173	28.9	5.93
SED	0.4	2.8	3.9	0.57

Data are means of three test crosses per line and 3 years of replicated evaluations in managed terminal stress environments in the dry season at ICRISAT-Patancheru. [SED, standard error of the difference; Adapted from Bidinger et al. (2000)].
