The search for novel technologies that would boost the yields of hybrid cultivars to yet new heights challenges breeders. One to date little exploited approach is the vigor of fecundation caused by allopollen. In this setting the heterosis in allopollen-induced weight gain was estimated as well as the grain preference for allopollen fecundation in relation to plant-own pollen (selfpollen). The experiment was carried out at the Universidade Federal de Lavras (UFLA) in the crop year 2004/2005. Two single-cross hybrids with white and three with yellow endosperm were crossed using the same amount of pollen. A preference of 80.06% for allopollen fecundation was observed, against 19.94% for autopollen. Heterosis obtained by allopollen in maize plants was 11.90 %, demonstrating that allopollen combined with the xenia effect contributed to a higher grain weight and consequently an increased mean plant yield. |
