| description | In the present investigation g x e interaction of twenty seven feed barley genotypes were evaluated at fifteen locations by
non parametric measures. Results based on nonparametric measures do not require distributional assumptions for testing of
effects. JB322 was high yielder followed by PL890 & HUB250 among studied genotypes. CMR and CSD measures
pointed towards HUB113, NDB1634 and UPB1054, JB322 as desirable genotypes by respective measures. Si
1 and Si
2
measures identified JB322 and UPB1054 along with UPB1054 & HUB 113 as of stable yield performance. Values of the
sum of Zi
1 and Zi
2 denoted significant differences among feed barley genotypes across 15 studied environments. Genotypes
UPB1054, HUB113, BH1005 based on Si
3 and Si
6 were identified as the stable genotypes whereas KB1436 & RD2552 were
unstable. First two NPs were very similar for unstable performance of RD2552 and last two NPs for similar behaviour of
HUB250. Biplot analysis observed highly significant negative rank correlation of yield with corrected mean yield, SD and
no significant correlation with MR. |
