Heterosis in mulbeny was studied for leaf yield and its component characters in
15 hybrids developed from 8 parents comprising of 3 females and 5 males. Analysis
of variance showed significant differences among the parents and crosses. Greater
variability in the parents indkated the possibility of getting higher heterosis in the
crosses. None of the crosses showed uniformity in the heterosis for yield components.
However, significant positive heterosis to the magnitude of 46.76 to 72.27% over
better parent, 34.7 to 149.69% over mid parent and 38.1 to 38.54% over standard
variety (SI)was observed among the crOGses for leaf yield. Heterosis breeding in
mulbuny, thus, found to be quite achievable, though mulbuny is known to be
highly heterozygous. Berhampore-l x KajIi seems to be highly promising for future
