ABSTRACT
Heterosis study was conducted using 28 hybrids developed by 8 x 8 diallel analysis (excluding reciprocals) at Main Wheat Research Station Vijapur, S.D. Agricultural University, Sardarkrushinagar during rabi 2008-09. Out of 28 crosses eight crosses manifested significant and positive heterobeltiosis for grain yield per plant. The range of heterobeltiosis for grain yield was wide (-53.95 % to 66.98%). The hybrid GW 399 x GW 404expressed the highest heterobeltiosis for grain yield per plant (66.98 %) and grains per spike (55.08 %). The hybrid GW 392 x GW 397 expressed highest heterosis over better parents for grain protein (9.61 %) and sedimentation value (11.7 %).
Key words :
Diallel analysis, heterosis and heterobeltiosis, Triticum aestivum, wheat.
