AbstractAs part of measures to combat protein shortages in form of meat analogues, extrusion processing conditions for the development of Texturized Vegetable Protein (TVP) from under-utilized sources (Lima bean and African oil bean seed) are analysed. Optimum parameters for processing were established as being: barrel temperature (92.45°C), screw speed (101.48 rpm), feed moisture (59.63%) and African oil bean seed protein concentrates (AOBSPC) of 1%. Concentrations of essential amino-acids were also found to be significant (0.90-7.3%) with a near absence of anti-nutritional factors (0.0022–1.0008) g/kg. Sensory evaluation showed that TVP5 (100% LBPC) compared favourably with the control sample (cooked meat) in overall acceptability. An Acceptable and nutritious meat analogue had been developed.

The present investigation was undertaken to study the frequency of chlorophyll deficient sectors and chlorophyll mutants induced by Gamma rays at the dosage of 240Gy,300Gy,360Gy,420Gy, Ethyl Methene Sulphate (EMS) at the concentrations of 0.25%,0.50%,0.75%,1% and the Combination of both (Gamma rays and EMS) like 240Gy+1%, 300Gy+0.75%, 360Gy+0.50%, 420Gy+0.25% in the variety ‘King of Garden’ Phaseolus lunatus (lima bean).The chlorophyll mutants were observed in all the three mutagenic treatments in the lima bean. These mutants were White (Albina), Yellow (Xantha), Yellow green (Chlorina) and Light green (Viridis). They were screened after 10-15 days of old seedling and were found at the margin of the leaflet or the entire leaflet.Induced mutation in the sectors of the leaves resulted into chlorophyll chimeric plants. The scoring of chlorophyll mutation frequency in M2 generation was one of the most reliable measures for evaluating the mutagenic induced genetic altercation of the mutagen treatments used in the ideotype. The frequency of chlorophyll mutants increased with the increase in the dose/concentration of the mutants. They can be screened and enhanced through mutation breeding for enormous yield.

Lima beans are an important crop in Delaware and the Mid-Atlantic Region. In the summer of 2000, five commercial cultivars (3–28, 184–85, C-elite Sel, Butter Bean, and Jackson Wonder) of lima bean in Delaware, Maryland, and New Jersey were observed with white, appressed mycelia on infected pods that appeared distinctly different from signs of downy mildew infection caused by Phytophthora phaseoli. Isolations were made by placing diseased pods between layers of rye media (1). A fungus that produced white mycelia with sporangia was consistently isolated. All Phytophthora isolates from the infected pods were heterothallic, grew at 35°C, had as much as 100 μm long pedicles on varying shapes of caducous sporangia with tapering base and >2 papillae, and were identified as P. capsici (2). Initially, three surface-disinfected pods from cv. Early Thorogreen plants grown in the greenhouse were floated on 20 ml of sterile water in a petri dish, and each was inoculated with a disk of P. capsici. This was repeated for nine isolates obtained from lima bean. After incubation for 7 days at room temperature, all 27 pods were infected, and P. capsici was reisolated from all the pods. A pathogenicity test was performed on the same cultivars from which the original field isolates were collected. Three seedlings and two plants with mature pods were inoculated with a sporangial suspension of each of the nine isolates and placed in a dew chamber for 5 days at 20 to 25°C and 100% relative humidity. White mycelial growth was observed on seedlings and mature pods. One inoculated plant developed brown-to-black stem lesions with white mycelia. All pods on the mature plants showed appressed, white mycelia identical to that observed in the commercial lima bean fields. P. capsici was consistently reisolated from all inoculated plants. In 2000, most infected pods in infested fields were observed low in the plant canopy or touching the soil. However, in 2001, infected pods were mostly in the lower and mid-portion of the plants observed in baby lima bean fields in Kent County, DE. References: (1) C. E. Caten and J. L. Jinks. Can. J.

Objective. This study has been conducted to determine the protein efficiency ratio (PER) of selected indigenous legumes, namely pigeon pea (Cajanus cajan) and lima bean (Phaseolus lunatus), as alternative protein sources. Methods. Experimental diets (pigeon pea-based and lima bean-based) and control diet (casein-based) were formulated and standardized using proximate analysis to have 10% protein basal diet based on the Association of Official Analytical Chemists (AOAC) guidelines. Diets were given to corresponding groups (2 experimental, 1 control) using 30 albino Sprague-Dawley weanling rats aged 21 days old, over a 28-day growth assay. Results. Results showed that the mean final weight and weight gain were significantly higher in rats fed with caseinbased diet (p<0.05 for both parameters) compared to those fed with pigeon pea-based diet and lima bean-based diet. The two experimental groups showed no significant difference between their mean final weights and weight changes (p=1, p>0.05). The PER of the casein (3.37 ± 2.71) is higher than that of the pigeon pea (1.87) and lima bean (1.32). These results can be attributed to the presence of anti-nutritional factors (ANFs) in the seeds of pigeon pea and lima bean. Reduced protein intake (due to bitter taste), toxicity, and interference with protein digestibility (through interaction with digestive enzymes) imparted by these ANFs can explain the weight loss among the experimental groups and consequently the low PER. Heat treatment done in the study were not adequate to remove the ANFs. Conclusion. The study shows that pigeon pea and lima bean as protein sources alone are not as adequate and efficient in providing necessary protein requirements for weanling rats. Proper processing and treatment should be done to remove inhibitors of protein digestibility and quality.

The Cost

Three species of pod borers, Maruca testulalis (Geyer), Etiella zinckenella (Treitschke), and Fundella cistipennis (Dyar), were found commonly in 1985-36 infesting wild and cultivated leguminous plants in all parts of Puerto Rico. E. zinckenella and M. testulalis were about equally numerous, but the latter, because it confined its attacks almost entirely to cultivated plants, was by far the most important economically of the two. F. cistipennis was the least abundant of the three species, and although it was found largely in cultivated plants, it was much less destructive than either of the other species. In addition to various legume crops the insects attacked several wild legumes, particularly Crotalaria incana L., one of the Island's commonest Crotalarias, and Canavalia maritima (Aubl.) Thou., commonly called the bay been. Some wild legumes, such as the wild lima bean (Phaseolus lunatus L.), and one of the commonest Crotalarias, (C. retusa L.), appeared to be highly resistant, if not inmune, to attack. The pod borers deposit their eggs on or near the blossoms and blossom buds, thereby assuring ample food for the newly hatched larvae. Most of the injured blossoms drop to the ground, and it is not uncommon to find hundreds of them on the ground under bean plants. Experiments conducted at Yauco, Isabela, and Mayagüez indicated that the pod borers could be successfully controlled by two 25-pound-per-acre applications of dust containing 80 percent of natural cryolite. Similar applications of pyrethrum dust were moderately effective, but the cost of the material was prohibitive. Dusts and sprays containing rotenone failed to provide satisfactory control. Observation of various varieties and types of lime beans indicated that the small-seeded lima bean, particularly the variety Carolina, was highly resistant to pod borer attack.

Callosobruchus Phaseoli

An invasive seed-beetle species cowpea weevil Callosobruchus phaseoli (Gyllenhal, 1833), was found in the south-eastern Kazakhstan (Almaty city) for the first time. Its areal includes India (species origin), South and Central America, Europe, Middle East (Israel), North Africa, Arabian Peninsula, Far East, China, Japan, Sri Lanka, Indonesia, Burma, Philippines, Hawaiian Islands, Australia, and Oceania. Damaged plants are adzuki bean Vigna angularis (Willd.) Ohwi &amp; H. Ohashi (1969), mung bean Vigna radiata (L.) R. Wilczek, broad bean Vicia faba Linnaeus, 1753, pea Pisum sativum Linnaeus, 1753, pigeon pea Cajanus cajan (L.) Huth, 1893, hyacinth bean Lablab purpureus (L.) Sweet, 1826, Wisteria sp., lima bean Phaseolus lunatus Linnaeus, 1753, common bean Phaseolus vulgaris Linnaeus, 1753 and other species of beans, chickpea Cicer arietinum Linnaeus, 1753, Sesbania sp., rattlepod Crotalaria spectabilis Roth., lupine Lupinus sp. Emerged beetles immediately mate and begin to lay eggs on the same day. Beetle damage both in field and in storage. We were not able to find the species during the monitoring of agriculture lands and natural landscapes near the city. We assumed that the invasion occurred recently and the species did not have time to spread outside Almaty. Since C. phaseoli was discovered in Almaty, which is a transit crossroad for many trade routes, further species distribution should be predicted. The most probable corridor for further invasion of cowpea weevil in Kazakhstan is the south and southeast parts of the country, namely Almaty, Zhambyl, Turkestan, and Kyzylorda oblast's.
