What makes sorghum drought tolerant?

Its tolerance to drought is a consequence of heritable morphological, and anatomical characteristics (such as thick leaf wax and deep root system), physiological responses (such as osmotic adjustment and stay green trait) and adaptive mechanisms that allow tolerance under extreme drought conditions (reviewed in [14]).

Is sorghum more drought tolerant than maize?

Moench.] is a candidate bioenergy feedstock in the Midwest, US. Research suggests that biomass sorghum is more drought tolerant and has higher water-use-efficiency (WUE; the ratio of cumulative biomass production to total evapotranspiration; g kg-1) than Zea mays (maize) in water-limiting environments.

Are sorghum and millet drought resistant?

Millets and sorghum are grains that are nutrient-rich, drought-tolerant crops and can support communities around the world.

What is sorghum breeding?

In sorghum, breeding procedures for self-pollinated crop are followed as it is predominantly a self-pollinated crop. It allows cross-pollination to some extent, and availability of male sterility sources made it easy for breeder to exploit heterosis in the form of hybrids.

Where can I find sorghum breeding and genetics?

SORGHUM BREEDING AND GENETICS – PURDUE UNIVERSITY The sorghum improvement program at Purdue University is very comprehensive encompassing the genetic improvement and management of several essential traits of the crop.

How is sorghum used in the developing world?

We conduct interdisciplinary research in the improvement of sorghum for biotic (diseases and parasitic weeds) and abiotic (drought and cold tolerance), as well as nutritional quality and biofuel efficiency traits of a uniquely versatile crop that has immense potential value in both developing countries and the developed world.

What are the effects of gene action on sorghum?

The effects of gene action on sorghum for yield and protein quality are essential for researchers and plant breeders for their breeding programmes aiming to develop hybrids and for further genetic improvement. Moreover, outcomes of nutritional quality studies are of paramount importance to scientists in various research disciplines.

What makes corn more tolerant to the drought?

Drought tolerance is an important attribute of commercial corn. The plant hormone ethylene is known to play a key role in drought tolerance; in particular, lower ethylene levels result in higher drought tolerance.
