Heterosis studies for yield and its components involving Indica/Japonica wide compatible varieties in rice (Oryza sativa L.)

摘要

Trial was conducted with forty-two hybrids involving Indica / Japonica crosses. The results revealed that the hybrid Palawan / ASD 18 and BPI 76 (G) / ASD 18 h-ad the highest standard heterosis for the number of grains panicle~(-1) and single plant yield, respectively. This shows that these hybrids can be utilized for further yield improvement.
