Abstract

The use of salicylic acid as resistance inducers agents in several plants species was well known. Salicylic acid has been believed to play an important role in inducing resistance against some pathogen. This research was aimed to study the role and effectiveness of salicylic acid as inducers for the resistance of some rice variety against bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae. The experiment was arranged in completely randomized factorial design with three factors i.e. rice variety, salicylic acid, and pathotypes, each treatment was replicated three times. The results showed that salicylic acid could prolong the latent period of X. oryzae pv. oryzae pathotypes IV and VIII in paddy rice varieties Conde and Ciherang,  induce the resistance of rice varieties as well as reducing the rate of infection of the two mentioned pathotypes. Salicylic acid was also able to induce the resistance of Conde and Ciherang varieties in order to suppress area under disease progress curve (AUDPC)  of X. oryzae pv. oryzae pathotypes IV and VIII.

Abstract

The F1 hybrid sterility in indica/japonica crosses is the major barrier in developing hybrid rice varieties between these two diverse germplasm. The sterility problem in japonica/indica hybrids can be overcome by using wide compatibility genes. The objective of this study was to identify wide compatibility varieties (WCVs) in some tropical japonica rice. Twenty five tropical japonica varieties as male parents were crossed with indica (IR64)and japonica (Akitakomachi) testers as female parents. The crosses were planted following a randomized complete block design with three replications. Varieties having average spikelet fertility of more than 70% with both the indica and japonica testers were rated as WCVs. Result from this study showed that six tropical japonica varieties were classified as WCVs, i.e., Cabacu, Grogol, Kencana Bali, Klemas, Lampung Lawer, and Napa. Hybrid sterility is caused by partial sterility of male and female gametes. The WCVs from the present study can be used in hybrid rice breeding program to solve hybrid sterility in indica/japonica hybrids.

Abstract

Sorghum development in Indonesia is directed towards cultivation in dryland and acid soil with low P availability. This research was aimed to obtain information on the performance of sorghum traits for selection in P deficient environment at early vegetative phase (3 weeks after planting), agronomic and yield potential traits in both P sufficient and P deficient environments, also to select high productivity sorghum genotypes which could tolerate P deficiency. The genetic materials used were 19 F7 recombinant inbred lines from a cross of B69 x Numbu developed under optimum condition (indirect breeding) by single seed decent. Variety Numbu and B69 used as checks. This research was conducted at The Indonesian Center for Biotechnology and Agriculture Plant Genetic Resources experimental field, Bogor, from May to September 2017. The experiment used a randomized complete block design with 3 replicates. The results showed that agronomic and yield traits varied among inbred lines under low P condition and optimum P condition. Adaptive lines showed better growth and yield compared to sensitive ones under low P condition. Plant height, panicle weight, and grain weight per panicle had high estimates of broad sense heritability. Selection based on stress tolerance index was able to identify inbred lines 286-6, 115-9, 114-7, 331-8, 170-9, 151-8, 104-7, 413-7, 68-5, 315-6, and 341-7 as tolerant to low P condition.Keywords: heritability, indirect breeding, optimum P condition, stress tolerance index

Abstract

A study to explore the agronomic response of some soybean genotypes to temporary flooding in the type-B overflow tidal swamp and to obtain the adaptive genotype to the environment was arranged in a split-plot design at coordinates 2°64?46.77? S and 104°75?27.75? E with an altitude of 3.5 m above sea level. The main plot was subject to short-term flooding with a variety of cultivation technologies consisting of saturated soil culture (SSC) for one month without flooding, SSC for one month with flooding, SSC during plant growth without flooding, SSC during plant growth with flooding and non-SSC/dry cultivation. The subplot was soybean genotype consisting of 6 genotypes: Tanggamus, Karasumame (Naihou), M652, Anjasmoro, M100-47-52-13, and Tachinagaha. The result showed that impaired soybean growth at the beginning of the growth stage caused pressure on the later growth stage and decreased soybean yield. Short-term flooding reduced the soybean yield. The non-tropical genotypes of Karasumamae (Naihou), M652 and Tachinagaha produced the lowest yield of seeds; 20% lower than the tropical genotypes of Anjasmoro, M100-47-52-13 and Tanggamus with SSC during plant growth without flooding treatment. The Karasumame (Naihou) genotype produced the highest seed yield of the three non-tropical genotypes. Anjasmoro and M100-47-52-13 produced the highest seed yield at temporary flooding.

Abstract

Twenty-nine soybean genotypes originating from various countries were evaluated on the tidal swamp of Indonesia to obtain information of agronomic character diversity as the soybean response to the environment and to obtain adaptive genotypes that can be used to develop soybean genotypes for the land. This study was conducted in a complete randomized block design with 3 replications. Diverse genetic backgrounds, countries and climatic regions of the 29 soybean genotypes were responsible for the difference in agronomic responses among the genotypes. All temperate and sub-tropical genotypes were able to produce seeds in the tropical type-B overflow tidal swamp. Adaptability based on seed yield resulted in 1 highly adaptive, 17 adaptive, 5 moderately adaptive and 6 non-adaptive genotypes. Adaptive and highly adaptive genotypes produced 1.56 - 2.58 tons ha-1 of seeds. Karasumame (Naihou), a subtropical genotype, produced the highest seed yield which was 65% higher than Indonesia average soybean productivity and 225% higher than soybean productivity with non-saturated soil culture technology on the tidal swamp. This study concluded that temperate and subtropical genotypes could be used as germplasm sources for soybean development in the tropical type-B overflow tidal swamp in Indonesia.

Abstract

A study was conducted to study correlation between some characters of upland rice and path coefficient analysis, which will be helpful for further selection process to improve upland rice in acid soils. The results of evaluation of lines for Al-tolerant in acid soils revealed that number of tillers and filled grain per panicle were inherited with high heritability and directly affected grain weight and contributed indirectly to the correlation between grain weight and other characters. However, indirect selection through number of tillers and filled grain per panicle was less efficient than direct selection through grain weight.

Abstract

Development of Crops Variety Tolerant to Low-light Intensity for Intercropping. The effort to increased food crops production is limited by the lack of arable land. Therefore, there is a need to utilize marginal areas such as land under estate crops which is partly shaded and hence have low light intensity as well as high acidity and drought condition. Production increase is marginal areas, such as lands under canopies of estate crops, could be achieved by improvement in (1) crop adaptation to abiotic stresses and resistance to biotic stress, (2) yield potential, and (3) cultural techniques which are based on knowledge in plant physiology and ecophysiology. A collaborative research on plant physiology, molecular biology and plant breeding is affected to be able to create approviate technologies to overcome those problems. Food crops which are potential to be produced under shaded condition as intercrops are upland rice, soybean, taro, elephant foot yams, and legume crops. Plant adaptation to low-light intensity is achieved through efficiency in light interception (avoidance) and utilization (tolerance). Through integrated research of interdisciplinary approach several promising lines of soybean having high productivity under 50% shading were selected.

Abstract

As a tropical country, Indonesia certainly is not the most suitable place for producing wheat. Wheat flour consumption however, had increased tremendously during the last three decades, that import of wheat grain in 2012 reached 7.2 million ton. Producing wheat had been attempted since 1990’s, utilizing lands at high elevation with drier climate. However, crops competition, especially with the high land vegetables, had put wheat cropping become prohibitive. As early as in 1880, G Wallace experimented of growing wheat in the high land of Timor island. However the crop was never economically established. Selection for genotypes and varieties of wheat for the tropical area had been attempted since 1980’s, and adaptable varieties to the high land had been released, but farmers did not adopt the crop on their cropping system. Breeding research to develop tropical wheat varieties was revived in 2009. By using the modern breeding techniques, including biotechnology, cellular somatic mutation, as well as applying the conventional breeding techniques, varieties adaptable to the lowland tropics are expected to be identified.
