Title

EVALUATION OF COMBINING ABILITY AND HETEROSIS OF PHENOLOGICAL AND MORPHOLOGICAL TRAITS AND SEED YIELD IN BREEDING LINES OF SUNFLOWER USING LINE×TESTER ANALYSIS IN SUMMER CROPPING CONDITION

Pages

  1-17

Abstract

 Combining ability and heritability of yield and yield components of SUNFLOWER (Helianthus annuus L.) breeding lines was studied using line×tester analysis. Eight lines and six testers which were tolerant to plasmopara (Plasmopara halstedii) disease were crossed in line × tester method.48 F1 single cross combinations along with their parents and two checks including Azargol and SHF81-85 were planted in simple LATTICE DESIGN with two replications. The results of analysis of variance revealed significant differences among the genotypes for all the traits including plant height, life-cycle duration, duration of flowering, grain yield, seeds per head and OIL YIELD. Line×tester analysis based on Comstock and Robinson design II displayed significant effects of genotypes, parents and hybrids for all the studied traits. For growth period, RF81-25, AF80-488/1/2/1 had significant negative general combining ability effects. For duration of flowering, RF81-30, AF80-533/1/1/1 had also significant negative general combining ability effects. For seeds per head, RF81-25, AF80-488/1/2/1 and also for seed yield and OIL YIELD, RF81-150/1 and AF80-488/1/2/1 maintained significant positive general combining ability effects. The crosses including AF80-460/2/1/1× RF81-25 and AF-6937×RF81-30 had significant positive specific combining ability for seed and OIL YIELD. Maximum heterosis effects for seed yield were belonged to AF80-960×RF81-25.
