Other claims from this paper (19)
- Observation Hybrids and parents differed significantly across studied traits.
- Observation P5 x P6 had mid-parent heterosis for early yield of 98.51 %.
- Observation P1 x P4 had mid-parent heterosis for early yield of 90.24%.
- Observation P1 x P6 had better-parent heterosis for early yield of 78.95 %.
- Observation P5 x P6 had better-parent heterosis for early yield of 73.91 %.
- Observation P4 x P6 had mid-parent heterosis for total yield of 75.0%.
- Observation P5 x P6 had mid-parent heterosis for total yield of 60.38%.
- Observation P4 x P5 had mid-parent heterosis for total yield of 59.65%.
- Observation P4 x P6 had better-parent heterosis for total yield of 61.77%.
- Observation P4 x P5 had better-parent heterosis for total yield of 46.77%.
- Observation P5 x P6 had better-parent heterosis for total yield of 37.10%.
- Observation General combining ability was significant for most traits, except early yield and shape index.
- Observation Specific combining ability was highly significant for most traits, except node number of female flower and early yield.
- Observation GCA estimates exceeded SCA estimates for most studied traits.
- Observation Both additive and non-additive gene actions were positive for all traits.
- Observation Broad-sense heritability ranged from 72.95 to 99.46 %.
- Observation Narrow-sense heritability ranged from 28.49 to 81.94 %.
- Recommendation P1, P2 and P3 are recommended as good combiners for fruit weight, vitamin C, fruit number and yield.
- Recommendation P5 and P6 are promising parents for growth, flowering and soluble solids traits.
