A half diallel mating scheme of five genotypes of papaya were evaluated in the field. The combining ability analysis revealed that both the additive and nonadditive gene effects were present. Crosses between the resistance and susceptible genotypes showed intermediate disease reaction to papaya anthracnose disease (PAD) suggesting a polygenic system of resistance to the disease. Highly resistance heterosis of 51.51% at Tajur and 48.71% at Gunung Geulis were expressed in crosses between IPB5 x PB000174 . Key words: Papaya, anthracnose, GCA, SCA, heterosis

This study was conducted on basis of screening natural infection in the field and artificial infection in laboratory. The research was conducted in the field (Saree Aceh and East Aceh) and in the Plant Pathology Laboratory, Agriculture Faculty, Syiah Kuala University. The study started from March to November 2013. Results from the field and laboratory, based on artificial inoculation, showed that three genotypes originated from Saree Aceh i.e. SR 26, SR 40 and SR7 were resistant, indicated by the characters of long incubation period (more than five days), a small diameter of spot, slow growth of the spot, and low percentage of symptoms. The three genotypes had both a good wounded post-penetration and unwounded pre-penetration resistance. Conversely, cacao genotypes originated from East Aceh did not show a significant difference of post-penetration resistance.

The study was carried out in Cot Irie Village, Aceh Besar Regency, from August to November 2017. This research was designed using a non-factorial Randomized Block Design (RBD) with a factor tested: five varieties of sweetcorn (Bonanza, Secada, Royal Sweet, Sweetboy and Manise), replicated 4 times. The total was 20 experimental plots with 20 plants in each plot. The data collected were analyzed using F test and the significant differences were compared using LSD at probability level 5%. The results showed that each variety demonstrated difference character on its growth, potential and quality of yield. The results exhibited that the sweetest corn was possessed by variety Royal Sweet. There was a correlation between growth and yield characters of sweet maize, revealed by significant positive correlation on plant height, stem diameter, height of main cobs, number of cobs, cobs length, diameter of cornhusk and number of seeds per row for comparison with dry seed weight per plot. .

Soybean crop had a critical period of weeds competition so that siam weed organic mulch should be applied to control weeds at certain time. The research aims to improve the yield of soybean crop that is influenced by application times of siam weed mulch. This study had defferent time of mulch aplications treatment such as at the time of planting, 7 days after planting (DAP), and 14 DAP. The results of this reserch showed that application times had not effected significantly at all parameter. The result also showed the earlier application time of siam weed organic mulch it was on planting time had decreased weed growth then increased yield of soybean.

One of the major losses in chili farming is the pest attack, such as whiteflies (Bemisia tabaci Genn.), a virus vector. Evaluation of the resistance of pepper plant germplasm against Begomovirus infection needs to be carried out, evaluate genetic diversity, estimate heritability values, and obtain a selection character for the resistance of chili plants Begomovirus. This research was conducted at Experimental Garden, Faculty of Agriculture, Universitas Syiah Kuala, and the Laboratory of Genetics and Plant Breeding, Faculty of Agriculture, Universitas Syiah Kuala from January to May 2020.

Tissue culture is one of the alternative techniques for vegetative propagation that produce the large numbers of seedlings and uniform in a relatively short time, and also does not depend on the season. A preliminary study to induce callus and embryo somatic cocoa clones adaptive in Aceh has been carried out using immature flower parts of cocoa. The result showed that picloram was able to produce somatic embryos of staminode of various explants. Callus growth began to appear after two weeks on staminode, and then were subcultured into the same medium to produce secondary somatic embryos.
