Traditional rice varieties

In addition to traditional methods, advanced biotechnologies, especially CRISPR/Cas9-mediated genome editing, have emerged as effective tools for improving important agronomic traits in rice. However, the critical step for utilizing these systems is to develope an effective system for rice transformation and regeneration.

Coastal Odisha is one of the most flood prone areas of India where the paddy crop in the wet season is often devastated by flash floods with an average productivity of only 0.5–0.8 t ha⁻ ¹. The present study showed that farmers preferred to cultivate low yielding traditional land races owing to their better flood tolerance and the unavailability of flood tolerant high yielding varieties (HYVs).

Cooking and eating quality of rice is predominantly influenced by various physio-chemical characteristics of starch. This study was aimed to characterize the physio-chemical properties of starch in commercially and traditionally cultivated rice varieties using Rapid Viscosity Analyser (RVA) in relation to identify the genotype with prominent starch composition to maximize the consumer’s acceptability.

Prior to the introduction of the modern varieties, the rice crop survived for centuries with traditional varieties with robust plant type but low yield. The farmers started applying higher doses of fertilizers in general and nitrogen in particular as these varieties were fertilizer responsive and these changes in rice cultivation resulted in an altered microclimate, which led to the accentuation of the insect pest and disease problems. Many diseases such as sheath blight, sheath rot, false smut and leaf scald have become severe in several parts of the country.

Paddy is a predominant kharif crop of Uttar Pradesh as well as the country and plays a major role in augmenting the income of small and marginal farmers of Chandauli district of Uttar Pradesh. One of the major constraints of traditional paddy cultivation is low productivity due to non-adoption of recommended package of practices and improved varieties.

The KVK, Mangan, North Sikkim conducted On Station Trials and Frontline Demonstrations to evaluate the suitability and profitability of high yielding rice variety Abhishek over local variety Attey as check in different locations. Improved organic cultivation practices were followed for the Abhishek variety and traditional farmer practices for the local check variety. The results indicated that the yield increase of 46.34 to 51.72 percent in Abhishek variety was recorded over local variety. Highest yield of 37.70 qt/ha with net return of Rs. 1,22,500 and C:B ratio of 2.

An investigation was carried out at ZARS, VC Farm, Mandya during 2015 to study the variability produced in two F2 populations of rice viz., ‘Rajamudi × BR-2655’ and ‘Rathnachoodi × BR-2655’ with 500 single plants to estimate the variability, heritability, genetic advance and genetic advance as percentage. The results showed that PCV values in general were higher than GCV for various characters studied. The high PCV and GCV values was obtained for grain yield per plant and low PCV and GCV was observed for thousand grain weight and panicle length.

Rice is known as the ‘grain of life’. It is the staple food for more than half of the world’s population. Due to processing, alteration of nutritional quality takes place either by changes in nutrients or by an improvement in digestibility of nutrients. Hurum, komal chaul, bhoja bora, puffed rice, popped rice, flaked rice, korai, sandahguri are the rice products obtained from specialty rice varieties of Assam. A unique characteristic of these rice products is that the products can be used instantly.

The diagnosis of places of varietal diversity of rice in Guinea was made from survey data from several farms in 41 villages themselves distributed in the 2 natural regions of Lower Guinea and Forest Guinea. The descriptors used are the number of known varieties and varieties cultivated at different scales, as well as their utilization rate. The latter makes it possible to classify the Sativa and Glaberrima varieties at the village level and to identify improved and local varieties of notoriety.

With the advent of the Green revolution high yielding varieties had their upper hand and the medicinal properties of landraces and the traditional rice varieties became an ignored experience. Traditional rice varieties are a consortium of desirable traits such as high yielding, tolerance to extreme stress conditions and also are rich in nutritive and therapeutic value. They have reduced sugar content and are preferred by people who are trying to regulate their sugar intake or suffering from diabetics, overweight. They are rich in vitamins, fibre and glutamic acid.

Bhagalpur district of Bihar has been a traditional aromatic rice growing area, where the varieties, like Katarni, Tulsi Manjari, Badshahbhog, Br-9 and Br-10 are most common. This variety has been given Geographical Indication (GI) due to its unique and special quality trait which develops only in its GI territory area. Despite its uniqueness katarni rice is facing the threat of extinction, mainly due to declining irrigation facility, adoption of other high yielding rice varieties and adulteration by traders of non- aromatic rice grains with katarni with the profit motto.
