Heterosis for Yield and Yield Components in Basmati Rice

Aditya Kumar, Surendra Singh and Sumer Pal Singh

Abstract:
Basmati rice varieties are well known for their pleasant aroma and good grain and cooking quality characteristics. These varieties are in general, poor yielders. The yield potential of basmati varieties can be enhanced by the exploitation of heterosis as also reflected by the huge success of PRH 10. Keeping in view, the significance of heterosis, 28 F1 S excluding reciprocals were developed using 8x8 diallel. Mid parent, better parent and standard heterosis were estimated for yield and its components. Crosses Pant Sugandh Dhan 15 x UPR 2845-6-3-1, Pant Sugandh Dhan 15 x UPR 3003-11-1-1 and Pant Sugandh Dhan 17 x UPR 3003-11-1-1 had shown high standard heterosis for grain yield (309.53, 244.45 and 255.56%), biological yield (158.47, 150 and 124.58%) and for harvest index (58.6, 37.8 and 58.4%).
