of 984.37 kg/ha and coefficient of variation 39% (Table 1). 48.5% of the accessions showed above the mean value
(Figure 7). Accessions such as acce # 10 067, 10 061, 10 084, 10 069, 13 755, 10 070, 10 054, 10 068, 241 826,
10 064, and 10 150 were high yielding, which ranged between 1 592 kg/ha to 1 990 kg/ha. Similarly, Wakjira
(2011) reported high variation in yield per plant. Significant variation in seed yield was also reported by ottai et al.
(2012).
1.8 Correlation analysis
Correlation coefficient analysis is presented (Table 2). This analysis depicted that seed yield had highly significant
postive association with plant height (0.215 9), number of secondary branches (0.204 8), and number of capsule
per plant (0.384 6), while it recorded significant negative relationship with days to maturity ( -0.142 6) and number
of primary branches (-0.298 2). Similar results were recorded on days to maturity, number of secondary branches,
and number of capsule, but the opposite for number of primary branches (Savita, 2006). Number of capsule had
also significant positive association with seed yield (Popescu et al. 1999; Belete and Wolde Yohanes, 2013). Days
to maturity showed significant postive correlation with number of primary branches (0.142 9). Number of
secondary branches recorded significant postive association with plant height (0.147 8), number of primary
branches (0.203 7), and number of capsule per plant (0.515 3).

2 Materials and Methods
The present study was carried out at Holetta Agricultural Research Center in 2012 cropping season. The
experiment was laid out using augmented design with no replication, and 202 accessions including checks were
grown in two rows of 3 m length and 30 cm between rows. All the management practices were followed as per the
