Evaluation of sunflower lines and their crossing combinations for morphological characters,yield and oil contents

The present study investigates sunflowers parental lines viz.,ts-1,t-4,ts-7,ts-11,tr-1,tr-2,tr-120,smtr-17,tr-6023 and their crossing combinations for their morphological characters and oil content. the experiment was laid out in rcb design with four replications at agriculture research institute (ari),tarnab,peshawar,kpk. significant (p<0.05) variations were observed for all the parameters under investigation. maximum seed yield (1.2 ton ha-1) was produced by tr- 6023 when compared with parental lines. among the crossing combinations,maximum seed yield (2.8 ton ha-1) was recorded by ts-7 x tr-6023 while minimum (1.08 ton ha-1) in ts-11 x smtr-17. maximum oil content (42.00%) was noted in tr-120 while minimum (35.00%) in tr-6023. in case of crossing combinations,maximum oil content (49%) was recorded in hybrid ts-7 x tr-6023 while minimum (31.00%) in ts-11 x tr-120.
