Stability analysis for grain yield and it's components in sunflower
Author(s): Patil DS, Rajmane VB, and Shinde SR
Abstract: A field experiment was carried out at four environmental condition to study their stability during kharif 2014, with twelve sunflower hybrids. G×E interactions were found to be significant, indicating presence of sufficient genetic variability among hybrids and environments studied. The data was recorded and subjected to analysis of stability as per Eberhart and Russell (1966). The hybrids SVSH-501, SVSH-481 and SVSH-497 were found to be superior and average stable, SVSH-495 was exhibited below average stability, SVSH-508 was exhibited above average stability for days to 50 per cent flowering. The hybrid SVSH-487 was found to be superior and having average stability for days to maturity. The hybrid SVSH-454 showed average stability, while SVSH-495 was exhibited below average stability for plant height. The hybrid SVSH-501 was found to be superior and with average stability for head diameter. The hybrid SVSH-481 was found to be superior and with average stability for no. of seeds/head. The present study indicates that sowing of sunflower hybrids on the date E1 (1st June) followed by E2 (15th June) found to be most favourable for expression of yield and yield contributing traits. It is concluded that SVSH-481 from high yielding group and SVSH-480, SVSH-501 and SVSH-497 from average yield group were observed to be stable for yield and yield contributing characters.
