Fig. 1. Ranked estimates of general combining ability effects for (a) grain yield per season, (b) grain yield per day, (c) time to flowering, and (d) plant height based on evaluation of 11 pearl millet parental populations and their 55 crosses across five environments in peninsular India during 1993 to 1995. For each character, the 11 parental populations are arranged along the x-axis in rank order (from lowest to highest) of the sums of their ranks for general combining ability effects for that character across all five environments. Deviations from a 1:1 line are indicative of rank-change-type genotype x environment interactions for that character. Key: = ranked sum of ranks across all five environments; = ranked sum of ranks across three rainy season environments (not irrigated) at Patancheru; • = ranks in one irrigated hot dry season at Patancheru; = ranks in one irrigated cool dry season at Bhavanisagar.
