Identification of quantitative trait loci under drought conditions in tropical maize 1 flowering parameters and the anthesis-silking interval. Female flowering, male flowering, anthesis-silking-interval, yield, ears per plant, and plant and ear height were measured except for male and female flowering and anthesis-silking interval at aya65, acid soil environments tended to have less the genetic variance. Anthesis and silking were defined according to borr s et al (2007) in each year, gy p was corrected to 0% moisture content for each plant, r6 tb.

Crop science abstract - crop physiology & metabolism modeling anthesis to silking in maize using a plant biomass framework. Elsevier field crops research 48 (1996) 65-80 field crops research the importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize j bolafios , go edmeades maize physiologists, cimmy~, apdo 6-641, 06600, mdxico df, mexico received 7 december. The corny news network was created by rl (bob) nielsen, extension agronomist at purdue university the articles written for the cnn pertain primarily to corn production & management issues important for indiana corn growers and their consultants. Ing, resulting in an increase in the anthesis-silking interval (asi), which is an important cause of yield failures in fact, typical visual symptoms of drought stress in maize  are a change in color from green to greengray, and rolling of the lower leaves followed.
Length of the anthesis-silking interval (as i), and yield losses are more severe (grant et al, 1989) selection for grain yield under drought condition has often been considered ineffi-cient because of the low heritability especially as yield de. Correlation and path coefficient analysis for yield contributing and quality traits in quality protein maize (zea mays l) ramesh kumar 50 per cent silking, anthesis silking interval, days to 75 per cent brown husk, plant height, ear height, ear length. Genetic variation, heritability, genetic advance and agronomic character association of yellow elite inbred lines of maize data were collected on days to anthesis and silking, anthesis-silking interval, plant and ear heights, number of ears per plant, leaf area. Article modeling anthesis to silking in maize using a plant biomass framework the capacity to predict time to silking relative to anthesis in maize (zea mays l) has important implications for breeding and seed production we developed a theoretical. Abbreviations: asi, anthesis-silking interval dap, days after planting gdd, growing degree days lai, leaf area index nie, nitrogen internal use efficiency nre, nitrogen fertilizer recovery efficiency nue, nitrogen use efficiency postdm, post-silking dry.
Length of the anthesis-silking interval and yield losses are more severe (grant etal, 1989) selection for gram yield under drought condition has often been considered ineffi- cient because of the low heritability especially as yield de.

Seedling emergence, anthesis-silking interval, days to anthesis and silking had high heritability but the genetic coefficient of variations was low this indicates that though, the character is highly heritable.
Term name: anthesis silking interval term accession: to:0000463 aspect: plant_trait_ontology synonyms (3) antskit, asi, flwslkinter definition. Stress, anthesis - silk interval and corn yield potential july 2, 2012 icm news by roger w elmore to tasseling and silking (vt and r1) as of july 1st one of the best indicators of how plants respond to stress during flowering is the anthesis silk interval. 106951 early drought can reduce maizeggrain yield by shifting both the time of pollen shedding and silking without extending the anthesis silking interval. Pollination underway in april planted corn you are here 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.
View rebekah arnold's profile on linkedin obtained silking-anthesis notes of hybrid fields conducted a research project focusing on the effects of plant density on the silking-anthesis interval of inbred production fields. There is a strong positive relationship between all of the measured traits, except anthesis-silking interval (asi) this pattern approximately repeated during three years also, correlation coefficient between grain. When maize (zea mays l) is stressed at flowering because of deficits of water, light, nutrients, and sometimes by long photoperiods and lack of thermal adaptation, ear growth slows in relation to tassel growth and the anthesis-silking interval (asi) increases this appears to be a general. Preferred name: anthesis silking interval synonyms: asi antskit flwslkinter definitions: a difference of the average number of days between the maize tassel flowering and the first visible silk (stigma) on the maize ear.
