Which is drought resistance variety of rice?

Sahbhagi Dhan (IR74371-70-1-1) is a conventionally bred, drought-tolerant rice variety identified in 2009 by the Central Variety Release Committee (CVRC) and released for cultivation in India, in 2010.

Is rice drought-tolerant?

Severe reduction in germination and seedling growth is observed under drought stress due to the scarcity of water (Vibhuti et al., 2015). Unlike some other crops, rice is extremely sensitive to drought conditions during the germination and early seedling growth stage.

What is drought resistant varieties of palay?

These include Sahbhagi Dhan in India, the Sahod Ulan in the Philippines, and the Sookha Dhan varieties in Nepal. Across these varieties, the average yield advantage of drought-tolerant varieties over drought-susceptible ones is 0.8-1.2 tons per hectare under drought.

How does drought affect rice?

Across all the studies, drought significantly decreased the agronomic traits of wheat and rice (see Figure 1) with biomass and yield showing the largest decreases. Drought decreased wheat biomass and yield by 25.0% and 27.5%, respectively, and decreased rice biomass and yield by 25.2% and 25.4%, respectively.

Which one of the following is a drought resistant rice variety of India?

Suvarna as a rice seed variety has been quite popular in India for many years mainly in Andhra Pradesh, Karnataka and Tamil Nadu. IRRI, ICAR and CRRI incorporated submergence resistant properties in the traditional varieties and made a new seed which was readily accepted by farmers.

What is salt tolerant rice?

Salt-alkali tolerance in rice is defined as the ability to grow on land with a 0.3% saline-alkali concentration, with a yield of more than 4500 kg per hectare. Through years of hard work, breeders have sought out, collected, evaluated, and developed many salt-tolerant rice resources.

Which one of the following is a drought-resistant rice variety of India?

What is scuba rice?

The rice, known as scuba rice, is flood resistant. It can breathe underwater for up to two weeks and recovers once the waters subside.

Is rice sensitive to salinity?

Salinity reduced crop yields in the lower basins of a number of fields. The literature indicates that rice is sensitive to salinity, particularly during the seedling stage (Maas and Hoffman 1977).

Is rice sensitive to salt?

On the basis of tolerance ability toward salinity, rice is considered as salt-sensitive crop, and growth and yield of rice are greatly affected by salinity. In general, rice can tolerate a small amount of saltwater without compromising the growth and yield.

What are the characteristics of the drought-tolerant crops?

Characteristics of Drought Resistant Plants

• Increased photosynthetic efficiency:
• Low rate of cuticular transpiration:
• Deposits of lipid layers:
• Reduction in leaf area:
• Waxy leaf surface:
• Stomatal frequency and location:
• Effect of awns:
• Accelerating water uptake:

Which type of varieties are more drought-tolerant?

Examples of current commercial drought tolerant plants In field trials, canola with YPT had 26% more seed yield with moderate drought stress than control canola. YPT has been demonstrated in corn and petunia, and is currently being developed in soybean, rice, sorghum, cotton and turf grass.

Is scuba rice genetically modified?

The latest variety of rice to be stored successfully has been aptly named “scuba rice.” Scuba rice has been genetically modified to withstand being submerged in flood water, and has been successfully grown in the large rice producing communities of Southeast Asia and researchers are currently investigating how to grow …

What characteristic of rice enables breathing under submerged condition?

Several varieties have a “snorkel” gene, which allows a rice plant to grow quickly to escape floodwaters. The snorkel trait is useful in some areas, but only if the field stays flooded the entire growing season.

What is salt-tolerant rice variety?

Pokkali type of rice varieties are highly salt-tolerant and commonly grows in coastal areas of Kerala State, India. It is a traditional, tall, susceptible to lodging, photoperiod-sensitive rice variety with low tillering and long, broad, dark, and droopy leaves. It has red pericarp and poor grain quality.
