Title : Heterosis for Yield and Yield Components in Rice Material Type: printed text Authors: Joshi, Bal K., Author Publication Date: 2000 Article on page: 6-13 p. Languages : English (eng) Keywords: F1, heterobeltiosis, hybrid vigor, Oryza sativa, standard heterosis Abstract: It is important to know the degree and direction of hybrid vigor for its commercial exploitation.
Heterobeltiosis and standard heterosis were studied in 14 crosses between rice (Oryza sativa L.)
cultivars (improved and landraces) and three wild aborted male sterile parents. These crosses
showed marked variations in the expression of heterobeltiosis and standard heterosis for yield and
yield components. Grain yield manifested highly significant heterobeltiosis and standard heterosis
in five crosses. Heterobeltiosis ranging from –55 to 139% and standard heterosis from –11 to
369% were observed. Highest heterotic effect among the yield components was for panicle
number plant-1 followed by spikelet number and panicle length. With appropriate choice of
parental lines, it is possible to develop F1 rice hybrid possessing distinct yield superiority over the
best-inbred lines.Link for e-copy: http://elibrary.narc.gov.np/?r=86
