STABILITY PARAMETERS IN MACARONI WHEAT

Published on

The stability parameters for six traits related to quality and productivity performed in a
U-parent diaUelmating techniques ofmacaroniwheat (Triticum durum Desf.) are reported.
The genotypes interacted significantly with environment for aU the characters. Nonlinear
components revealed highly significant difference for reproductive phase, seed hardness,
protein content, and gluten content. The parent varieties Jori 'c' 69 and Raj 911 appeared
to be more adapted as they exhibited nonsignificant deviation from regression, regression
coefficient less than unity, and high grain yield. Jori 'c' 69 also showed adaptation for
gluten content. Twenty cross combinations in Fl generation exhibited better stability for
higher grain yield in comparison to their parental performances. The hybrids Meghdoot X
WL 1002 and NP 404 x DWL 5023 were stable for seed hardness, protein and gluten content.
