Heterosis in Soybean [Glycine max (L.) Merrill]

摘要

Ninety soybean hybrids derived from a line x tester analysis along with their parents were evaluated at the Research Farm of Kisan (PG) College, Simbhaoli, to estimate heterosis over mid- and better-parent. Heterosis was positively significant for yield m 15 hybrids over better-parent and in 24 hybrids over mid-parent. Heterosis for yield was generally accompanied by heterosis for number ot seeds/pod, number of pods/plant and pod length. For protein 16 and for oil 31 hybrids exhibited significant positive heterosis over better parent. In view of the availability of genetic male sterility, the study revealed good scope for commercial exploitation of heterosis for yield and oil contents in soybean.
