Abstract

The research was aimed to characterize agronomic characters and physico-chemical tubers of early maturating cassava clones. Total of 10 cassava clones and five varieties (UJ 3, UJ 5, Adira 1, Adira 4 and Malang 6) were evaluated in two locations, namely at the experiment station of Muneng, Probolinggo and at farmer’s land in South Malang. The experiment was planted in April to November 2009, using a completely randomized block design with three replications. Each clone was planted in plots measuring 5 m x 4 m with plant spacing of 100 cm x 80 cm. Fertilization was applied in three stages by using 10 t/ha of manure and 200 kg urea + 100 kg SP36 + 100 kg KCl/ha. Manure was given at the time of land preparation, while urea, SP36, and KCl were given at one month after planting (MAP) (100 kg of urea, 50 kg of KCl, 100 kg of SP36/ha), and three MAP (100 kg of urea and 50 kg of KCl/ha). Observations on the agronomic characters included: plant height, number of fresh leaves, number of node and diameter of stem conducted at 3 WAP until the harvest, at intervals of 1 month. Yield and yield components, and physical-chemical characters of tuber were measured at harvest. Combined analyses of two locations showed that the interaction between clones and locations were significant on all observed agronomic characters. OMM 9076 clone was consistently out yielded at two locations. Based on physicochemical characters, CMM 03001-10, CMM 03094-12, CMM 03009-6, CMM 03097-11, CMM 03013-11, CMM 03094-13, CMM 03018-10, M4-p, OMM 9076 and Adira 1 clones were considered suitable for food. Clone M4p was also suitable for starch or flour industries, and CMM 03013-11 was suitable for ethanol.

Abstract

Tolerance to shade among mungbean genotypes were assessed based on their environmental stress tolerance indices (ITC). Through an approach of direct and indirect relationships between quantitative characters, quantitative characters that play roles in mungbean tolerance to shade was identified. The trial was conducted at Kendalpayak Experimental Farm, Malang. Treatments were without shading and with a 52% shading using 12 mungbean genotypes representing 9 genotypes tolerant to shading and susceptible genotypes. Under each shaded environment, the treatments were arranged in a randomized block design with three replications. Observations were carried out on plant morphology (leaf number, leaf area, specific leaf area, leaf hairs number, plant height, stem diameter, age of flowering and harvesting, number of pods, pod dry weight, seed weight and seed size) and leaf anatomy (thickness of leaves, epiderm cells, palisade tissue length, and number of leaf stomates). Mungbean genotypes that were tolerant to shading had different plant morphology and leaf anatomy from those of susceptible genotypes. The tolerant mungbean genotypes had larger leaves, less number of leaf hairs, thicker leaves, thinner leaf epidermal cells, longer palisade tissue, more number of stomates, higher contents of chlorophyll a and b, larger diameter of stem, higher pod dry weight, larger seed size, and higher grain yields than those of the susceptible genotypes. Three characters of mungbean plants that need to be taken into account in determining tolerance to shade were the leaf area, number of leaf hairs, and seed weight per plant. Selection of the immatured beans can be done using indirect selection based on the three characters, namely stem diameters at 2 and 4 weeks after planting (WAP), plant height at 4 WAP, and weight of 100 seeds.
