Rank based non-parametric measures of grain yield for rainfed barley genotypes evaluated in northern hill zone

Simple descriptive statistics based on ranks of 19 genotypes evaluated at 8 locations in northern hills of country showed HBL723 and HBL737 as stable genotypes, while BHS400 and UPB1044 based on MR, VLB118 and HBL113 based on SD and VLB118 and BHS400 based on CV were unstable genotypes. Huehn's non-parametric measures based on original values indicated HBL72315, BHS43720 and HBL73716 were genotypes of stable performance, while VLB11811, HBL11319 were unstable genotypes. NPi⁽¹⁾ pointed towards VLB144 and VLB118 as stable and UPB1043 along UPB1044 unstable while, NPi⁽²⁾ showed VLB144, BHS352 and UPB1044 as sable and unstable, NPi³ found out HBL723 VLB144 and BHS400 and NPi⁽⁴⁾ identified VLB144 HBL723 and BHS400 as the stable genotypes and overall by most of measures VLB144 HBL723 and BHS400 VLB118 were stable and unstable genotypes. Highly significant positive rank correlation of yield with CV, Si³ and Si⁶ and highly significant negative with MR and Med were observed. Yield expressed highly significant positive relationship with NPi⁽²⁾, NPi⁽³⁾ and NPi⁽⁴⁾.
