- Abstract
Development of F1 combinations for improvement of yield and quality, need identification of good specific and general combiners. The investigationwas carried out at Experimental Farm, Mata Gujri College, Fatehgarh Sahib during 2018-2019. Experimental materials comprised 15 F1s from a line × tester mating design involving 8 parents and 1 check (Punjab Upma) with the objective of estimating heterosis and combining ability. Crosses 'EC-164863 × H-24' and 'EC-249504 × Azad T-5' had significant positive heterosis for total yield/plant. The general combining ability of parent 'EC-620395'exhibits positive significant effects for most traits followed by 'EC-914104' and 'EC-164863'. Of 15 three cross combinations 3 exhibited positive, significant, specific combining ability (SCA) effects for total yield/plant. The greatest SCA effect was for hybrid 'EC-620395 × H-24' followed by 'EC-165690 × H-24' for and 'EC-165690 × EC- 914104' were specify that these crosses may be further used for commercially and 'EC-620395' 'EC-914104' 'EC- 164863' tested for hybridization program.
