Abstract

Maize (Zea mays L., 2n = 20), a valuable crop, comes from Mexico to Central Africa and is a cross-pollinated, monoecious, annual plant in the family Poaceae. According to modern concepts, heterosis is the bringing of favourable genes from two different parents into the progeny to overcome barriers and obtain a better genotype with better yield. WINPOP-3×HKIPC-7 cross can be used in developing early maturing lines and WINPOP-8×HKIPC-7, WINPOP-8×HKIPC-5 for heterotic combination of yield per plant, is useful in developing high-yield superior lines with good popping quality. The best heterotic combination of yield per plant was WINPOP-8×HKIPC-7, WINPOP-8×HKIPC-5 over standard checks, which can be further exploited in developing high yielding and popping quality.

Keywords

Heterosis, Popcorn, Popping Volume, Early Maturity

Conclusion

The WINPOP-3×HKIPC-7 cross can be used in developing early maturing lines as this corss combination showed heterbleitosis and standard heterossis for days to 75% maturity, days to 50% anthesis, and days to 50% silking.
