Abstract

Production of high yielding hybrid cultivars is among the main objectives of breeding programs in SUNFLOWER and on evaluation of the COMBINING ABILITY of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. This study was conducted to investigate the general and specific COMBINING ABILITY and the mode of inheritance for agronomic and SEED QUALITY traits in some inbred lines of SUNFLOWER. Nine inbred lines of SUNFLOWER were each crossed with three male sterile inbred lines and then their hybrids (27 hybrids) evaluated for agronomic and SEED QUALITY traits. The data were analyzed based on the factorial model (Design II of Comstock and Rabinson) in a randomized complete block design of two replications. The results indicated that the additive genetic effects were more important than the non-additive effects of genes in the genetic control of days to flowering, days to maturity and seed oil content. The specific COMBINING ABILITY values for days to maturity and seed oil content varied from -3.67 to 4.50 days and from -2.89 to 2.42%, respectively. Both additive and non-additive effects of genes were important in inheritance of plant height, head diameter, 1000-seed weight, seed and oil yields with the range of specific COMBINING ABILITY (in hybrids for these traits) being -10.40 to 14.5 cm, -2.38 to 2.49 cm, -9.83 to 7.70g, -802 to 836 kg/ha and -320 to 343 kg/ha, respectively. The existing genetic variation for general and specific COMBINING ABILITY for agronomic and SEED QUALITY traits indicate that this genetic variation can be well used for production of high yielding and high SEED QUALITY hybrid cultivars.
