Data were recorded on tillers m-2, grains spike-1, 1000-grain weight (g), biological yield (kg ha-1), grain yield (kg ha-1) and harvest index (%).
Path coefficient analysis revealed that plant height, peduncle length, tillers per meter, spikelets per spike, spike weight, number of grains per spike, harvest index and biological yield had positive direct effect on grain yield.

The mean squares due to treatment x genotype interactions were also significant for all these traits except that plant height, productive tillers/plant, grains/ spike and harvest index were non-significant.
1]) and harvest index (%) were measured by the ratio of fruit dry mass and total plant dry mass.
The harvest index reflects the ability of the genotypes to partition its dry matter into seed and straw, and the ability to maintain the right balance between seed and straw yield.
Yield potential was increased by improving energy interception efficiency and almost doubling the harvest index.
