 ABSTRACT

This investigation was carried to study the inheritance of pollen colour in sunflower (Two crosses for pollen colour). F1 selfed seeds of two crosses were raised during kharif season 2013 at Main Agricultural Research Station, Raichur (Karnataka). Inheritance of pollen colour in sunflower (Helianthus annuus L.) using two distinct colour morphs, yellow and white pollen colour. The two parents used in the study are 104B and 17B had yellow and white pollen respectively. The study consists of two crosses direct and reciprocal cross CMS17A x 104B (white pollen x yellow pollen) and CMS104A x 17B (yellow pollen x white pollen). The F1 plants showed yellow pollen in all the plants in both direct and reciprocal crosses which revealed that yellow pollen colour is dominant over white. The F2 generation of direct cross CMS17A x 104B exhibited 726 yellow colour pollen plants and 239 white colour pollen plants out of 965 total number of plants scored and in the reciprocal cross CMS104A x 17B out of 1017 F2 plants scored, 761 plants had yellow pollen and 256 plants had white pollen. In both the crosses the data showed good fit into 3:1 ratio indicating with dominance of yellow pollen over the white pollen with monogenic inheritance.
