ABSTRACT
COLEOPTILE LENGTH AND MATURE PLANT HEIGHT ASSOCIATION IN DURUM WHEAT, Triticum durum Desf.

Carmen Sanz de Cortázar1, Ernesto Hacke E.2, Ignacio Ramírez A.3
 
Coleoptile length and mature plant height association was studien in 154 mutant durum wheat lines, selected in the M3 and M7 generations of the cultivar Candealfen 5 (Triticum durum Desf.) treated with chemical mutagenics (EMS and DS),and 23 non treated durum varieties and experimental lines. No positive correlation and no significant chi square for independence were found between coleoptile length and mature plant height in the mutant lines. On the contrary a highly significant correlation (P = 0.01) and a statistically significant chi square value (P = 0.05) were obtained between the two studied characters in the non treated material.
