Eight Saltol quantitative trait locus (QTL) linked simple sequence repeat (SSR) markers of rice (Oryza sativa L.) were used to study the polymorphism of this QTL in 142 diverse rice genotypes that comprised salt tolerant as well as sensitive genotypes. The SSR profiles of the eight markers generated 99 alleles including 20rare alleles and 16 null alleles. RM8094 showed the highest number (13) of alleles followed by RM3412 (12), RM562 (11), RM493 (9) and RM1287 (8) while as, RM10764 and RM10745 showed the lowest number (6) of alleles. Based on the highest number of alleles and PIC value (0.991), we identified RM8094 as suitable marker for discerning salt tolerant genotypes from the sensitive ones. Based upon the haplotype analysis using FL478 as a reference (salt tolerant genotypes containing Saltol QTL), we short listed 68 rice genotypes that may have at least one allele of FL478 haplotype. Further study may confirm that some of these genotypes might have Saltol QTL and can be used as alternative donors in salt tolerant rice breeding programmes. © 2016 Prof. H.S.

Genetic Resources and Crop Evolution

During survey and field collection of crop genetic resources in diverse parts of north east India, the authors came across Plukenetia corniculata Sm. under cultivation at field as well as homestead level for use as a leafy vegetable, a species otherwise known under cultivation from Southeast Asia. Its preference over other leafy vegetables by the Naga tribes was noted during market survey in Dimapur and Mokokchung districts of Nagaland. Apart from being delicious and easy to cultivate, higher nutritive values in the edible portion indicate its potential for popularization. Detailed information on botany, ecology, cultivation and utilization is provided here. Collecting more diverse germplasm, identifying elite types and their biochemical characterization, and developing standard cultivation practices would aid in popularising the crop at the country as well as regional level. © 2015, Springer Science+Business Media Dordrecht.

The study of the Trichosanthes cucumerina group from India based on field investigations, followed by herbarium and literature-based study, distinguishes four taxa, two of which are new combinations. Trichosanthes lobata Roxb. is synonymized to T. cucumerina L. subsp. cucumerina. Also associated with the autonymic subspecies, the cultivar 'Anguina' is newly recognized as T. cucumerina subsp. cucumerina 'Anguina' K. Pradheep, D. R. Pani & K. C. Bhatt [≡ T. anguina L.]. Trichosanthes brevibracteata Kundu var. sublobata Kundu is transferred as T. cucumerina subsp. sublobata (Kundu) K. Pradheep, D. R. Pani & K. C. Bhatt. Trichosanthes villosula Cogn. is transferred at reduced rank as T. cucumerina subsp. villosula (Cogn.) K. Pradheep, D. R. Pani & K. C. Bhatt [≡ T. villosula Cogn.], and T. perrottetiana Cogn. is synonymized to this subspecies. Source

Ninety lowland rice cultivars of the eastern region of India were collected and screened for submergence and water logging tolerance and further used for validating the efficiency of molecular markers and their combinations for submergence tolerance. Submergence tolerance and elongation ability of the tested genotypes were measured in screening tanks along with tolerant and susceptible checks. The genotypes FR13A, Khoda, CR Dhan 300, Savitri Sub1, IR64 Sub1, IC-568009 and IC-568842 exhibited high submergence tolerance may be used as donor in the breeding program. Landrace 'Khoda' showed tolerance to submergence with moderate elongation ability for adaption. Boitalpakhia, Gayatri, Atiranga, Aghonibora, Chakaakhi, Moti, IC-567993 and IC-568921 possessed both characters of moderate elongation ability and moderate tolerance to submergence. Both of these traits are required for lowland varieties of eastern India to survive under flash flood and accumulated stagnant water conditions. RM8300, Sub1A203, AEX, Sub1BC2 and Sub1C173 were employed for molecular screening to identify the submergence-tolerant genotypes. Sub1A203 was capable of differentiating the tolerant and susceptible genotypes into groups. RM8300 and Sub1BC2 could also differentiate the genotypes with inclusion of some susceptible genotypes. The AEX and Sub1C173 marker could not show discrimination among the genotypes with respect to the traits. Using Sub1A203+Sub1BC2 was better amongst the combinations studied. The results of the study indicated a trend toward a negative association of Sub1BC2 with submergence tolerance while AEX and Sub1C marker did not show any significant association. The donors identified can be useful as parental lines while the molecular markers can be used for marker-assisted breeding work. © 2015 Académie des sciences. Source

Genetic Resources and Crop Evolution

The subterranean parts of many wild plants form an important constituent of traditional diet of the tribal inhabitants of Similipal Biosphere Reserve, Odisha especially in times of food scarcity during critical periods. However, no specific study has been made so far on this aspect. The present study was conducted during 2008-2012 as a search for sources of food and to assess the dietary diversity, consumption pattern, culinary uses and prioritized species of wild tuberous plants sustained by local tribes. The exploration and germplasm collection missions along with intensive botanical survey, focus group discussions, structured household interview and market survey were conducted in 30 villages interacting with 102 key informants of core and buffer zones. A total of 55 wild edible tuberous species representing 37 genera and 24 families were inventoried including 17 species used during food deficiency to meet seasonal shortages. The analyzed data contributed 5 use categories, 4 preparation methods, 7 kinds of food items, 10 species as children snacks, 35 species of pharma-foods and 20 prioritized species. Ten species were domesticated by tribes thus reducing threats on wild tubers and 20 species were traded in local markets to generate additional income exemplifying economic benefits from wild tubers. Seventeen species were identified as novel uses of food items from India. The findings suggested that the nutritional profile along with pharmaceutical attributes of preferred wild food plants be analyzed for recommending suitable species for better nutrition and development of nutraceuticals. Further, many genetic resources of these wild tuberous species of agri-horticultural importance constitute the wild genepool hence their economic and breeding potential along with desirable attributes need to be investigated for utilization in crop improvement programmes. © 2013 Springer Science+Business Media Dordrecht.
