Tlventy six sunflower (Helianthus annuus L.) cultivars were evaluated at National Agricultural Research Centre, Islamabad. The trial was planted on March 3, July 23, and February 5, during 1984, 1985 and 1986, respectively. Data on seed yield, days to flower initiation, days to flower completion, plant height, head diameter and days to maturity were recorded. Simple correlations between all traits were worked out and direct effects of agronomic characters on seed yield from path coefficient analysis were calculated. TWo hybrids, NS-Condor from Yugoslavia and IH-173 from Hungary,werehighyielding with average seed yield of 2374 and 2184 kg/ha, respectively. Days to flower initiation, days to flower completion and days to maturity ranged from 68,4 to 78.1,73.3 to 85.0 and 96.8 to 109.7, respectively. Cuhivars Thiumph 570, Peredovik (an open-pollinated) and Citosol-Fl, Citosol-4, and NS-Flowerwere taller than all otherentries. Hybrid NK-2l2wasmostconsistent for plant height and head diameter. All cultivars grew taller, took more days to flower and maturity and also gave higher yields in 1986 than both in 1984 and 1985. Variety x year interaction was highly significant for all the traits. Days to flower initiation, days to flower completion and days to maturitywere strongly and positively correlated with eâch other. Days to maturity showed significant and positive correlation with plant height. The only significant correlation with yield was that of head diameter. Direct effects from path coefficient analysis indicated that head diameter had a strong and positive direct correlation with seed yield while days to flower completion had a strong but negative correlation with seed yield.
