Detection of QTLs for Yield Heterosis in Rice Using a RIL Population and Its Testcross Population

Table 4

Broad-sense heritability (%) of the six yield traits.

NP	NGP	NSP	SF	TGW	GY
RIL	54.53	30.82	26.64	54.92	94.50	45.93
TC	60.51	32.63	12.27	66.17	84.93	51.22

, recombinant inbred line; TC, testcross F₁.
, number of panicles per plant; NGP, number of grains per panicle; NSP, number of spikelets per panicle; SF, spikelet fertility; TGW, 1000-grain weight; GY, grain yield per plant.
