High Yield Potential

Tidal swampland at present and in the future is very strategic as one of the national food barns considering sloping of productive land. In South Kalimantan, for example, tidal swamp paddy fields are available which is quite large, but the most are still planted with local varieties. More than 70% of rice cultivation in the tidal swampland is planted with various local varieties. The existence of local rice varieties is inseparable from its adaptability and acceptability factors. Among local varieties that are popular and widely planted by farmers are Siam Saba and Siam Mutiara varieties. Siam Saba and Siam Mutiara were released as local-improved varieties. Both of these varieties have their respective advantages, both from the distribution of plant adaptation and the potential benefits of yield. Siam Saba variety is widespread in tidal swampland of acid sulfate soil types and soils that are seawater intrusion in the dry season (near the coast) with A/B overflow type, while Siam Mutiara in acid sulfate tidal paddy fields with B / C overflow type. Some of the advantages of Siam Saba compared to other local varieties are high yield potential of 4.70 t / ha, a large number of tillers, small and slender grain shape, white rice color, and amylose content of 81.69%. Whereas improved of Siam Mutiara is high yield potential of 4.80 t / ha, the color of clean yellow grain, the color of clear and translucent rice such as pearl, and amylose content of 48.88%. Both varieties showed uniform in growth, flowering time, and ripening simultaneously, in mature panicles with almost no green grains, and a high percentage of unfertile grains. Local rice cultivation technology (Siam Saba and Siam Mutiara) indigenous knowledge here includes seedbed, transplanting, land preparation, fertilizing, pest disease control, harvest, and post-harvest processing or yields carried out by indigenous farmers. This indigenous cultivation technology until now in tidal swamp paddy fields of South Kalimantan is still widely practiced by farmers, especially for ownership of narrow or limited rice fields. There were advantages and disadvantages of each in the practice of indigenous cultivation technology.

Reduced productive rice fields to non-paddy fields, most possible extension of the nationalrice cultivation area to the suboptimal lands reaching ± 91.9 million ha. Technologypackages that can be applied include the use of new improved rice varieties through theassembling of varieties that have high yield potential, resistant to suboptimal soil stress. Theobjective of the research is to produce new superior rice varieties that are available invarious environments. The study used a split-plot design, as the main plot is an environmentconsisting of rice paddies and gogo, as a subplot is the genotype of rice. The treatment ineach environment is prepared using the Randomized Complete Block Design (RCBD). Thetreatment consisted of 10 new rice strains and four varieties as a comparison. Variablesobserved (1) plant height; (2) the maximum number of shoots; (3) number of productiveshoots; (4) long panicle; (5) the number of grains per panicle; (6) the amount of graincontent of each panicle; (7) the number of empty grains per panicle; (8) weight of 1000grains of grain; (9) grain yield of each clump; (10) grain yield per hectare. Data wereanalyzed by variance if there was a difference between mean, median treatment, followed byLsd test at 5% level. The adaptability and yield stability of each strain was determined basedon the value of the coefficient of diversity (KK) (Francis and Kenneberg, 1978) in Syukur etal., (2012). The results showed that seven new rice strains had adaptations both planted asupland rice and lowland rice, namely strains B3, B4, F2, F3, H1, H4, and L2.

The experiment was conducted at the Bangladesh Rice Research Institute Farm, Gazipur, in boro season to determine the optimum planting date and to select the varieties having high yield potential. Traditional aromatic photoperiod sensitive fine rice varieties; Kalijira, Kataribhog, Chinigura and Badshabhog were transplanted from 10 December and continued up to 25 January, both in 2000 and 2001 years, at an interval of 15 days. Forty-day old seedlings were transplanted spaced at 20 cm x 20 cm. Results exhibited that plant tallness, number of tillers and dry matter increased with the advancement of planting dates. On the contrary, the number of panicles, grains panicle-1, panicle length, grain yield, straw yield and growth duration decreased with delaying of planting dates. The intermediate short stature plant type of Chinigura exhibited higher number of panicles (300-331 m-2) and comparatively heavier individual grain (12.25-12.31 g), consequently gave higher grain yield (2.79-3.53 t ha-1 ) planted with in December. However, in late planted situation in 10 January Kalijira exhibited higher number of panicles, grains panicle-1, resulted higher grain yield than the rest of the varieties. Thus, cultivation of traditional aromatic fine rice Chinigura and Kalijira have the potentiality to produced higher grain yield when planted in early December in Boro season.

In developing new superior rice varieties, farmers’ preferences are important things to study and high yield potential. The study aimed to obtain new superior varieties of adaptive rice based on plant growth and productivity performance and determine respondents’ preferences for the varieties studied. The study was conducted in rainfed rice fields, Majalengka Regency, West Java Province, from April to August 2020. The study used a randomized block with 6 treatments: Inpari 32 varieties, Inpari 39, Inpari 42, Inpari 43, Pajajaran, and Siliwangi, and repeated 5 times. The observed parameters consisted of: growth, yield components, and yields were analyzed by ANOVA followed by Duncan’s Multiple Range Test at a 5% level. The respondent’s preference test for grain and rice and organoleptic characters used a Likert scale and analyzed non-parametrically (Friedman test). The results showed that the Inpari 43 variety gave the highest yield. Still, farmers preferred the Inpari 32 variety to be developed because it has characters favored by farmers (respondents), namely short plant height, a large number of tillers, thin grain shape, white rice color, and fluffier rice taste.

The experiment was conducted with different Basmati rice varieties at the Bangladesh Rice Research Institute (BRRI) farm, Gazipur during 1999 and 2000 T.aman season. Four rice genotypes (Basmati PNR, Basmati 370, Basmati 375 and Basmati-D) were tested with 0, 25, 50, 75 and 100 kg N/ha to determine the optimum N level as well as to find out the genotype having high yield potential. The plant height, tiller number, number of panicles, panicle length, spikelet sterility and straw yield increased with the increase of nitrogen levels upto 75 kg N/ha. Maximum plant growth at the highest level of N caused lodging of plant which increased spikelet sterility and lower number of grains per panicle and ultimately decreased grain yield. Genotype Basmati PNR having dwarf plant characteristics performed well at higher level of nitrogen (100 kg N/ha), while other genotypes having medium plant height responded well at lower level of nitrogen (52-56 kg N/ha).

Cooking And Eating Quality

The primary goals of rice breeding programs are grain quality and yield potential improvement. With the high demand for rice varieties of premium cooking and eating quality, we developed low-amylose content breeding lines crossed with Samgwang and Milkyqueen through the marker-assisted backcross (MABc) breeding program. Trait markers of the SSIIIa gene referring to low-amylose content were identified through an SNP mapping activity, and the markers were applied to select favorable lines for a foreground selection. To rapidly recover the genetic background of Samgwang (recurrent parent genome, RPG), 386 genome-wide markers were used to select BC1F1 and BC2F1 individuals. Seven BC2F1 lines with targeted traits were selected, and the genetic background recovery range varied within 97.4–99.1% of RPG. The amylose content of the selected BC2F2 grains ranged from 12.4–16.8%. We demonstrated the MABc using a trait and genome-wide markers, allowing us to efficiently select lines of a target trait and reduce the breeding cycle effectively. In addition, the BC2F2 lines confirmed by molecular markers in this study can be utilized as parental lines for subsequent breeding programs of high-quality rice for cooking and eating.

Secondary traits from high-throughput phenotyping could be used to select for complex target traits to accelerate plant breeding and increase genetic gains. This study aimed to evaluate the potential of using spectral reflectance indices (SRI) for indirect selection of winter-wheat lines with high yield potential and to assess the effects of including secondary traits on the prediction accuracy for yield. A total of five SRIs were measured in a diversity panel, and F5 and doubled haploid wheat breeding populations planted between 2015 and 2018 in Lind and Pullman, WA. The winter-wheat panels were genotyped with 11,089 genotyping-by-sequencing derived markers. Spectral traits showed moderate to high phenotypic and genetic correlations, indicating their potential for indirect selection of lines with high yield potential. Inclusion of correlated spectral traits in genomic prediction models resulted in significant (p < 0.001) improvement in prediction accuracy for yield. Relatedness between training and test populations and heritability were among the principal factors affecting accuracy. Our results demonstrate the potential of using spectral indices as proxy measurements for selecting lines with increased yield potential and for improving prediction accuracy to increase genetic gains for complex traits in US Pacific Northwest winter wheat.
