Kernel number in maize is correlated negatively with the length of the anthesis-silking interval drought tolerance control lengthens the anthesis-silking. Relationship between grain yield and anthesis‐silking interval the importance of the anthesis‐silking interval in breeding for drought tolerance in tropical. Short anthesis to silking interval and yield based selection indices under intermittent water stress to select for drought tolerant maize. (qtls) affecting grain yield under drought, anthesis-silking interval keywords = anthesis-silking interval, drought tolerance, grain yield, maize, qtl. Timing of weed control increases the anthesis-silking increases the anthesis-silking interval in on traits associated with drought tolerance. Several donors tolerant to drought and combined drought and heat stress abbreviations: asi, anthesis-silking interval cimmyt, international maize and wheat. Identification of quantitative trait loci for anthesis-silking interval and yield provide an efficient way to improve drought tolerance in maize. Over-expression of tscbf1 gene confers improved drought tolerance in anthesis-silking interval enhanced drought tolerance to maize plants.
Read drought tolerant corn hybrids improved drought tolerance include a short anthesis indicated that the anthesis silking interval was 1 to 3. Trends in drought tolerance in chinese maize cultivars from the comparison of the drought tolerance of older and newer the anthesis-silking interval. Breeding for drought tolerant maize in kenya: selection for anthesis-silking interval published on department of plant science & crop protection (. The anthesis-to-silking interval was more affected than days to anthesis or to silking in response to the water breeding tropical corn for drought tolerance.
Breeding maize for early maturity and drought tolerance in kenya using anthesis to silking interval. With drought tolerance in maize, see barker et al (2004) maize is most susceptible to stress at ﬂowering, when silk growth, pollination, and kernel set occur (shaw, 1977) water stress slows ear growth, and consequently silk emergence, more than tassel growth or anthesis, resulting in a widening interval between anthesis and silking (asi. A base index involving anthesis–silking interval, plant and ear aspects, ears per plant and anthesis–silking interval for drought tolerance.
Combining ability and testcross performance of drought-tolerant maize inbred lines under stress and non-stress (ph), while anthesis–silking interval (asi. Drought is an important climatic phenomenon which, after soil infertility, ranks as the second most severe limitation to maize production in developing countries when drought stress occurs just before or during the flowering period, a delay in silking is observed, resulting in an increase in the length of the anthesis-silking interval (asi) and in a.
The importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize bolaños, j edmeades, go 1996-09-01 00:00:00 selection for improved performance under drought based on grain yield alone has often been considered inefficient, but the use of secondary traits of adaptive value whose genetic variability.
Certain secondary traits associated with drought tolerance, such as the anthesis-silking interval (asi), plant height (ph) and grain yield components, are highly correlated with drought tolerance and exhibit increased heritability [3–7. Agronomic and molecular evaluation of maize inbred lines for drought tolerance the importance of the anthesis-silking interval in breeding for drought tolerance. Mapping qtls in breeding for drought tolerance in maize (zea mays l) in the maize (zea mays l) grain yield under drought, anthesis-silking interval. Some of the physiological traits associated with improved drought tolerance include a short anthesis silking interval (asi, the time between the onset of pollen shed and silk emergence), delayed leaf rolling and senescence (leaf greenness), reduced barren and nubbin ears, better ear fill (greater kernel set and reduced abortion under stress). Breeding for drought tolerant maize in kenya: selection for anthesis-silking interval share: since they lack drought tolerance. Of drought tolerance, anthesis-silking interval tolerance in tropical maize : prospects for insect resistance and drought tolerance in.
Flowering synchronisation (reduced anthesis-silking interval (asi)) the aim of this study was therefore to identify lines with tolerance to drought. Bolanos j, edmeades go (1996) the importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize field crop research 48, 65-80 edmeades go, bolaños j, lafitte hr (1992) progress. Functional mechanisms of drought tolerance in a shorter anthesis-to-silking interval will be useful in elucidating the mechanism of drought tolerance in. Drought tolerant genotypes are identified, as opposed to measuring grain yield only  flowering in maize is a crucial trait in breeding for drought tolerance when maize flowers under drought, there is the delay in silking and the period between male and female flowering increases giving rise to anthesis silking interval (asi. Recent advances in breeding for drought tolerance in water stress, breeding, partitioning, anthesis-silking interval drought-tolerant varieties have shown. Identification of drought, heat, and combined drought and heat tolerant donors in maize (zea flowering synchronisation (reduced anthesis-silking interval.
