Understanding the genetic mechanisms of soybean rust resistance is important for effective selection and breeding procedures. This study was hence conducted to determine the combining ability and gene action controlling soybean rust using a 10×10 half diallel mating design. The F2 segregating populations along with their parents were evaluated for rust severity and sporulation level at two reproductive stages (R4 and R6) in screen house and field conditions during the second season of 2016 and first season of 2017 at MUARIK using an alpha lattice design replicated thrice. Significant differences were observed among the parents and F2 generations for both disease severity and sporulation level. General and specific combining abilities were highly significant. The GCA/SCA ratio (1.50-2.30) and the Baker’s ratio (0.75-0.82) showed the predominance of additive gene action in the inheritance of soybean rust resistance. The broad-sense (0.94-0.99) and narrow-sense (0.73-0.82) heritability estimates indicated the possibility of improving resistance to soybean rust through selection in the early generations. UG 5, Maksoy 3N, Maksoy 4N and Maksoy 5N had negative GCA effects. The F2 populations derived from these parents crossed with Wonder soya and Nam 2 had also negative SCA effects. The use of these parents and F2 populations can, therefore, increase the response to selection for improving resistance to soybean rust.

The wheat aphid species individually and collectively cause severe damage to the wheat crop qualitatively and quantitatively. The incidence of these aphids is influenced by a number of biotic factors such as host plant resistance, availability of the natural enemies and the major abiotic factors such as temperature, humidity and rainfall. In the present investigation, the incidence and abundance of wheat aphid species were recorded with rapeseed as a perimeter crop. The results showed that wheat was infested by two major aphid species, bird cherry oat aphid, Rhopalosiphum padi and green peach aphid, Myzus persicae with rapeseed as a perimeter crop. The results further suggested that the level of infestation in wheat with perimeter crop remained low compared to check, influenced by the presence of natural enemies, however, the level of infestation of M. persicae remained highly influenced by the high level of infestation in rapeseed. In light of the above experimental results we concluded that the rapeseed influenced the population of R. padi and deterred S. avenae, however, encouraged M. persicae to infest wheat crop.

Natural regeneration of some commercial timber tree species following selective logging in a semi deciduous forest in the east region of Cameroon|JBES

By: Seraphine Ebenye Mokake
english language editing
JBES welcome all respective authors to submit their research paper/manuscripts, thesis paper in the field of Environmental Sciences, Biology, Biodiversity, Species diversity, Ecology, Taxonomy and many more via online submission panel
A critical step in sustainable forest management is to ensure the establishment and regeneration of seedlings and sapling of exploitable tree species following logging. Since selective logging is one of the main silvicultural practices in Cameroon, a detailed understanding of regeneration following selective logging is vital. 
english language editing

This study evaluated the natural regeneration of some commercial timber species in logged and unlogged forest types in two forest management units (FMU) in the East Region of Cameroon (FMU 10052 and 10025). Two transects of 5000 x 50m each were established in logged and unlogged forest types. Eleven commercial tree species were assessed for fruit fall, the number of seedlings established and the height increment of the established seedlings. Three of these commercial tree species fruited in both forest types. Fruit fall was significantly higher (p≤0.001)in the logged forest (492 fruits/ha)than in the unlogged forest (52 fruits/ha). Comparing species that fruited in both forest types Klainedoxa gabonensis recorded the highest number of fruit fall(84 fruits/ha) and least (0.24 fruits/ha) in the logged and unlogged forest types respectively. Seedling establishment was significantly higher (p≤0.001) in the unlogged forest (404 seedlings/ha) than in the logged forest (72 seedlings /ha). Seedling performance was better in the unlogged forest compared to the logged forest (low mortality rate). Due to the low seedling establishment and performance of these species in the logged forest, seed trees should be marked and protected prior and after logging as prescribed in the sustainable forest management.

Effect of storage methods of cassava planting materials on establishment and early growth vigour | IJAAR

By: Baraka Barnabas Mdenye
"" IJAAR welcome all of you to submit your research paper for publication in the field of Agriculture, Agronomy, Horticulture etc. Please submit your manuscripts via Online submission panel.""
Cassava (Manihot esculenta Cruntz.) establishment depends on quality of planting materials. The experiment was done to determine the effects storage and variety on crop establishment and early growth vigour. Karembo and KME 4 varieties were stored in clamp under double shade (CUDS), horizontal under shade (HUS), vertical under shade (VUS) and horizontal under open ground (HOUG) as control for 16 weeks.
Planting materials was sampled from each storage methods after every 4 weeks and taken to field to evaluate their sprouting ability, number of primary shoots formation, number of leaves, rate of leaf formation and early growth vigour. Data were subjected to ANOVA and means separated by LSD. Sprouting percentage at Kabete was 54.73 % while in Kiboko had 37.78 %. The results showed that Kabete had 1.60 number of primary shoots per plant compared to 1.04 of Kiboko. The results showed KME4 had higher sprouting than Karembo in both sites. This can be due to genetic difference among varieties. The rate of leaf formation at Kiboko was higher as compared to Kabete it could be contribute difference in temperature between locations. Thus, optimum temperature and relative humidity should be factored in cassava cuttings storage to avoid increased death of stored cuttings. In case of storage cassava cuttings, should be stored in clamp under double shade methods under low temperature and moderate RH.

Mode of inheritance of resistance to the stalk-eyed fly (Diopsis longicornis) in rice


Stalk eyed flies (D. longicornis and D. apicalis) are pests of economic importance on rice. Of the two species of stalk- eyed fly, D. longicornis is the most prevalent and destructive. To determine the mode of inheritance for resistance to the stalk-eyed fly in rice in Uganda, crosses were made among eight parental lines (NERICA4, TXD306, K85, NM7-22-11-B-P-1-1, NERICA1, NERICA6, NAMCHE2 and PAKISTAN) selected on the basis of their response to the stalk-eyed fly, high yield and early maturity. Of the eight, four genotypes [NERICA4, TXD306, and NM7-22-11-B-P-1-1 and K85], exhibited lower levels of deadheart occurrence and were crossed using the North Carolina II mating design with four susceptible genotypes [NERICA1 and NERICA6, PAKISTAN, and NAMCHE2]. Studies on combining abilities were conducted on 16 F1 hybrids along with the eight parents. Narrow sense coefficients of genetic determination (NSCGD) were low to moderate (0.09 – 0.33) and broad sense coefficients of genetic determination (BSCGD) were moderate to high (0.38 – 0.89) for traits studied. Both GCA and SCA effects were significant for percentage of deadhearts. However, Baker’s ratio was less than 0.5 (0.37) for deadhearts, indicating that both additive and non-additive gene effects were involved in resistance to the stalk-eyed fly, although non-additive gene effects were more important. NERICA4 andK85 were found to be good general combiners for increasing resistance. The crosses Pakistan × TXD306 and NERICA1× NM7-22-11-B-P-1-1 were identified as promising lines for advancement.
