Abstract

One of the weaknesses of the groundnut is the easiness to be infected by fungi, especially Aspergillus flavus that produces aflatoxin. Seed from the field experiments for all step of selection (F5 until to multilocation yield test) after processed then stored for 3 and 6 months, further tested their respons to A. flavus using a standard method. Examined for seed coat resistance to colonization of A. flavus were carried out in laboratory ILETRI (Indonesian of Legume and Tuber Crops Research Institute) since years of 2002 to 2006. Stability performance of resistance to A. flavus was analyzed with regression technique. Performance of resistance to A. flavus of selected lines tested were not consistant among 16 of testing envoronments. Among genotypes were also sigficantly different response to A. flavus invasion from location to location, indicated that those performance of some lines were not stable, except line of MHS/91278-99-C-180-5. The highest pod yield was occupied by line of J/91283-99-C-90-8 and stable, however its resistance to A. flavus did not stable. The resistance of J/91283-99-C-90-8 to A. flavus antil to three months after after seed strored similar with variety of J-11. Keywords: groundnut, Aspergillus flavus, aflatoxin

Abstract

The status of whitefly (Bemisia tabaci Genn.) as a major pest of groundnut had increased in the past few years. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. So far there has been no resistant groundnut genotypes identified as indicated by the number of whiteflies observed on each of groundnut genotype (256 whiteflies per accession). The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield. In this study, the pod yield criteria for resistance to whitefly were set up as follow: >1.2 t/ha = resistant (R); 1.0 to 1.2 t/ha = moderately resistant (MR), and <1.0 t/ha = susceptible (S). Based on these criteria and selection limit of 50% pod yield, 15 groundnut genotypes were found resistant to whitefly with pod yields ranging from 1.2-2.0 t/ha dry pods. Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Among these varieties, Takar 1 was the most resistant variety to whitefly. In order to maintain the resistance and to avoid the development of new strains of whiteflies, it is suggested that the planting of resistant groundnut should be integrated with selective use of insecticides.

Abstract

Salinity is a major abiotic stress limiting mungbean production worldwide including Indonesia. Since mungbean plant is very sensitive to salt condition, selection of salinity tolerant genotypes becomes important for mungbean improvement. The objective of this study was to evaluate the tolerance of eight mungbean genotypes to salinity at seedling stage under different levels. The experiment was arranged in a randomized complete block design with two factors (mungbean genotypes and salinity levels) and triplicates. Observation variables were germination percentage, vigor index, germination rate, hypocotyls length, epicotyls length, root length, number of root, seedling fresh weight, and seedling dry weight. The result showed that increasing level of salinity concentration inhibited the speed of germination, germination percentage, vigor index, normal seedling fresh weight, and number of lateral roots. Murai and Vima 1 were identified as tolerant genotypes, while Vima-2 and MLGV 0180 were identified as salinity sensitive genotypes at seedling stage. Currently, mungbean varieties with special characters, such as saline-tolerant is not yet available. The availability of saline-tolerant variety of mungbean is a cheaper and easier technology for farmers to anticipate the expansion of the saline area. The tolerant genotypes may be further tested at the later stage to obtain promising genotype tolerant to salinity that effectively assist mungbean breeding program.

Abstract

Soil-borne disease caused by fungus infection is one of the disease that causes the death and crop failure of mungbean. The aim of this study was to identify the performance, yield component and respons of plant to the disease. Performance of 25 genotypes were observed in installations research and assessment of agriculture technology (IPPTP), Jambegede of Indonesian Legumes and Tuber Crops Research Institute (ILETRI)at dry season 2018 using RCBD with three replications. The result showed that each variety has different characteristic. The plant with the highest number of plant height was genotype 15 and 18, while the total branches of 25 genotypes were generally similar (4).The highest number of grown and harvested plant was genotype 15. The genotypes with shorter flowering, maturity and harvesting age were 23, 20, 18, 15 and 10. The highest average number of filled pods was genotype 11 and empty pods was genotype 13. There were 8,10 and 2 genotypes with seeds weight of >7, >6 and <6 respectively. The highest yields were obtained from genotype 19 and 3 by total of yield of 2.0 t/ha and 1,9 ton/ha respectively. Resistance test against soil-borne diseases resulted 5 genotypes that were moderate resistant observed at 2 DAP. This research contributed to gave information about new genotypes of mungbean that potentially produce new superior varieties.

Abstract

Tingkat produktivitas kacang tunggak ditentukan oleh proses fotosintesis pada daun tanaman dan fotosintat yang dihasilkannya. Sebagai organ tanaman yang utama dan merupakan source, daun menjadi bagian yang paling penting dalam meningkatkan produktivitas tanaman. Kacang tunggak mempunyai macam bentuk daun antara lain: segitiga, trullate sempit, trullate sedang, bulat telur (ovate) dan hastate-lanset Penelitian ini dilakukan untuk mengetahui pengaruh bentuk daun terhadap produktivitas kacang tunggak. Percobaan disusun menggunakan Rancangan Acak Kelompok satu faktor dengan bentuk daun sebagai perlakuan dan diulang sebanyak enam kali.  Bentuk daun yang diuji ada empat macam, yaitu: Bentuk ovate/bulat telur, yang diwakili oleh varietas KT 4, bentuk lanset yang diwakili oleh varietas KT 5, bentuk trullate sempit yang diwakili oleh galur KT5/1716 (F1), dan bentuk trullate lebar yang diwakili oleh galur KT4/KT5 (F1). Tipe bentuk daun kacang tunggak mempengaruhi bobot biji per tanaman. Tipe lanset mempunyai bobot paling tinggi diikuti ovate dan trullate. Bentuk daun tipe trullate cenderung  mempunyai bobot biji lebih rendah dibandingkan bentuk daun ovate dan lanset..

Abstract

The peanut pod shell is composed of cellulose, lignin, and hemicellulose. It has pore channels that can give the seeds direct contact with the environment, resulting in the seeds quickly deteriorating due to temperature fluctuations. This research aims to determine the porosity of the pod shell of several peanut varieties, its relationship with the level of shell hardness, and its effect on seed deterioration that is indicated by seed viability. The research was designed using a randomized block factor design, with the first factor being the type of variety, consisting of Kidang, Hyphoma 3, Landak, Talam 1, Tasia 1, and Takar 1. The second factor was the length of storage, consisting of 1, 2, 3, and 4 months, in quadruplicates, and the hardness of the pods was measured using a digital grain hardness tester meter. Porosity (P) was determined using the volume method. Viability testing includes germination viability (GV), germination rate (GR), and germination rate index (GRI). Pod hardness had a low correlation (r = 0.43) with pod thickness and had no effect on shell porosity level; however, pod porosity level had a strong negative correlation (r = -0.75) with pod shell thickness. Pod shell porosity, GR, and GRI have an influence on seed germination following the regression equation GR = 145-1.85P - 0.41VG+29.93GRI with a coefficient of determination R2 = 0.50, meaning that these variables only have a contribution of 50% and other factors influence the other 50%. The shell thickness affects the level of seed germination. The Tasia and Landak varieties with a shell thickness of >0.75 mm produced lower porosity levels and had the least deterioration seed than the other four varieties. Keywords: germination viability, peanuts, pod hardness, porosity
