Short anthesis to silking interval and yield based selection indices under intermittent water stress to select for days to anthesis days to silking patterns of population structure in maize landraces from the central anthesis-silking interval and the patterns of population structure in this region. Some of the new drought tolerant hybrids have shorter “anthesis silking intervals”, ie pollen shedding and silk emergence are more closely synchronized than hybrids more susceptible to drought this shorter anthesis silking interval mitigates the impact of drought stress during pollination. Phosphorus fertilization improves growth analysis traits and reduces anthesis-to-silking interval leading to increased grain yield in maize.

Drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected to soil water deficit. Anthesis- silking interval (qasi-6), and two for stay green characteristic (qsg-1 and qsg-4) were close to their adjacent markers, with an interval.
Anthesis — silk interval: an indicator of stress one of the best indicators of how plants respond to stress during flowering is the anthesis — silk interval, asi this measures the time in days between pollen shed and silk emergence. The longer anthesis-silking interval are undesirable for grain yield production as the male and female parents do not synchronize well on the other hand, materials .
