Are nonwoven synthetic pollination bags a better choice for sorghum breeding?

This work investigated the effects of seven pollination bag treatments on three varieties of sorghum for: grain loss to birds; total weight of five panicles (g); total grain weight of five panicles (g); average grain weight per panicle (g); germination per cent; and occurrence of grain mold during 2016. Varieties were: 1167048 hybrid (brown seeded); BR007B (red seeded); and P9401 (white seeded). The bag treatments were:...

Field assessment of disease resistance status of some newly-developed early and extra-early maize varieties under humid rainforest conditions of Nigeria

Periodic assessment of resistant status of genetic materials in a breeding program is an important activity to ensure its continued progress. Forty newly-developed early and extra-early maize varieties were evaluated under natural field infection conditions for two years to assess their resistance status to some common diseases prevalent in the humid rainforest agro-ecology, and to determine effect of the diseases on...
