Abstract Seedling characteristics such as leaf emergency, chlorophyll content, and height
are important for early growth and also associated with seed size. Quantitative
trait loci (QTLs) for rice (Oryza sativa L.) seedling characteristics (leaf
length, chlorophyll content, seedling height) and seed size were identified with
an attempt to explore the relationship between seedling characteristics and seed
size, using a recombinant inbred population derived from a cross between
Zhenshan 97A and Minghui 63. Two, one, five, four, four, and nine QTLs were
detected for chlorophyll a content, total chlorophyll, length of the second
seedling leaf, length of the third seedling leaf, seedling height, and seed
size, respectively. The results indicated that four QTLs for seed size and four
QTLs for seedling characteristics shared several similar regions (G359-RG532,
C567-RG236, RZ403-R19, C371-C405a), respectively, suggesting a close association
between seedling characteristics and seed size. Several chromosomal regions
influencing seed size, however, had no effects on seedling characteristics,
suggesting that it was possible to improve seedling vigor without increasing
grain size.
