durum wheat, agronomic characters, accessions, correlations
Abstract
The correlations between the yield and the elements which determine it in 10 accesions of durum wheat have been studied. A positive correlation has been established between plant height and the last internode length (r=0.72). It was established that the length of the top /1 st / internode take about 40% of the total stem length. A positive correlation was found between the weight of seeds per plant and the productive tillering (r=0.81). The correlation between number of seeds per spike and weight of seeds per spike, number of spikelets per spike and weight of seeds per spike and the weight of seeds per spike and per plant is - 0.86, 0.83 and 0.76.Moderately the correlations exists between the weight of seeds from the main spike and from the rest stems and correlation between spike length and weight of seeds per spike (r=0.45 and r=0.36). A negative correlation between the weight of seeds per plant and mass of 1000 seeds was established (r=-0.51).
