Heterosis is a phenomenon whereby hybrids of inbred lines produce favourable phenotypes that exceed those of their parents. Traits of interest are higher yield and stronger stress tolerance. The two‐line super‐hybrid rice ‘Liangyoupei9’ (LYP9) shows superiority to both its elite inbred line ‘93‐11’ and ‘Pei'ai64s’ (‘PA64s’) parents and conventional hybrids. However, the genetic basis of its hybrid...

AbstractTo discover new resistance genes to rice stripe virus disease (RSVD), quantitative trait loci (QTL) analysis was conducted by using 162 recombinant inbred lines, derived from a cross between ‘Guichao 2’ and ‘Koshihikari’, RSVD resistances were evaluated using both artificial inoculation and natural infection methods by scoring the ratio of the disease rating index...
