The anthesis to silking interval anthesis to silking interval usefulness in developing drought tolerant usefulness in developing drought tolerant maize. Drought-induced changes in anthesis-silking interval are related to silk expansion: resulting in an increased anthesis-silking interval anthesis and silk. Analysis of variance for anthesis-silking interval (asi) revealed significant mean squares due to general combining ability (gca) and specific combining ability. 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.

Octa journal of biosciences anthesis-silking interval (asi) are some of the major initial traits indicating drought tolerance/ resistant nature of the crop. Hall et al 1981 1982 suggested that an increased anthesis silking interval from aec aec 302 at kentucky. 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. Qtl mapping for controlling anthesis-silking interval based on ril population in maize xiaohong liu1, zuping zheng2, zhenbo tan1. In maize, a major effect of water stress is a delay in silking, resulting in an increase in the anthesis-silking interval, which is an important cause of yield failures diverse strategies are used by breeding programs to improve drought tolerance.

The 95% genetic confidence interval of mqtl for grain yield and anthesis silking interval are shaded in green and pink colors, respectively, while those shaded in black coincided for both traits the mqtl detected in 4 populations are indicated on the right side of each chromosome. Pollination underway in april planted corn author(s): this shorter anthesis silking interval mitigates the impact of drought stress during pollination. We have determined the chromosomal locations of quantitative trait loci (qtls) affecting grain yield under drought, anthesis-silking interval.

Flowering time is a critical aspect of maize production that has been shown to impact crop yield, and drought is a major abiotic stress that can cause early arrest of maize flower drought increases the anthesis-silking interval (asi), resulting in. Abbreviations: asi, anthesis–silking interval blup, best linear unbi - ased predictor esa, eastern and southern africa h, broad-sense heri-tability 2 s. Identification of quantitative trait loci for anthesis-silking interval and yield components under drought stress in maize li xin-hai, liu xian-de.

anthesis silking interval Influence of drought on corn and soybean july 21, 2017 when combined with heat stress this delay could result in poor anthesis silking interval (asi.

A shorter anthesis silking interval should thus contribute to the pollination of a large number of differentiated florets (uribelarrea et al, 2002. Genetic analysis of selection response in maize populations we will focus on three morphological phenotypes, silking-anthesis interval, leaf angle.

Stress caused by early weed competition is known to delay the rate of maize development which may result in a decrease in kernel number kernel number in maize is correlated negatively with the length of the anthesis-silking interval (asi. Interval, anthesis-silking interval, silking-silk senescence interval of the hybrids have been examined dissecting the pp into four equal parts (percent. The duration of phase 3, between the end of cell division and the arrest of cell growth in silk apex, considerably increased with water deficit it corresponded to the anthesis-silking interval used by breeders to characterize the response of cultivars to stress. Read the importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize, field crops research on deepdyve, the largest online rental service for scholarly research with thousands of academic publications available at.

The interval is the difference in days between anthesis (also knowns as tassel emergence or pollen shed) and silking (or emergence of silk from the ear) heat and moisture stress is typical during august in ohio, which could delay both tassel and silk emergence and decrease pollination and yield (cicchino et al, 2010 edreira et al. Under combined stresses, which shortened the anthesis-silking period and interval (asi) that caused more kernel setting than suwan 4452), pioneer 30b80 failed to complete 100% silking under pbd silking was more affected than anthesis by both stresses especially under pbd. The anthesis-silking interval (asi) was determined as the days from silking to anthesis in the field of kaes, the plants were sown on 16 may in. In over 90% of the trials, ears plant−1, kernels plant−1, weight kernel−1, anthesis-silking interval (asi), tassel branch number and visual scores for leaf angle, leaf rolling and leaf senescence were determined low scores indicated erect, unrolled or green leaves.
