Ecological Region

North east hilly eco-region of India is characterized by highly undulating topography and fragile ecology. Here the cultivation of rice on upland and medium land is not a profitable venture to farmers. Therefore, to find out alternative crop with high yield potential cultivars a three year field study from 2008 to 2010 on agronomic evaluation of groundnut cultivars under sub-tropical climate of North East hilly Agro-ecological region was carried out. The experiment consists of fourteen groundnut cultivars (V1- ICGS-76, V2- GG-2, V3- GG-13,V4-TG 37 A, V5-FeESG-10, V6-FeESG-8,V7-K-134,V8-GG-6,V9-SB XI, V10 GG-11,V11-KAUSHAL,V12-GG-4,V13-GG-2,V14-GG-8) as treatment in randomized block design and replicated thrice. Results revealed that highest plant dry weight was produced by cultivar “KAUSHAL” (32.99 g/plant), while lowest was recorded with cultivar “FeESG-10” (16.32 g/plant). However, the highest numbers of pod (25.32) were observed with “ICGS-76”. Cultivar GG-11 had produced highest pod and seed weight (34.80 g/plant and 20.62 g/plant, respectively) as compared to other cultivars, while lowest pod and seed weight (8.96 g/plant and 6.39 g/plant, respectively) with “FeESG-8”. Maximum pod yield (2.06t/ha) was produced by GG-11 cultivars, although highest stover yield (2.37 t/ha) was produced in cultivar KAUSHAL. Cultivar GG-11 had also recorded highest shelling percentage. Therefore, it is suggested that GG-11 a better option for substituting the upland and medium land rice during kharif season for enhancing the farmer’s income.

Biodiversitas 21: 3929-3937. Bambara groundnut (Vigna subterranea (L.) Verdc.) is a potential grain, which can be considered as an alternative source of protein and carbohydrate. Due to unavailability of commercial bambara groundut cultivar in Indonesia, the characterization of bambara groundnut landraces is an important step before developing cultivar with traits of interest. The objective of the research was to access genetic variability of Indonesian landraces of bambara groundnut with different seed coat colors based on morphological and molecular markers. The experiment was arranged as split-plot in a complete randomized block design with the main plot was cultivation methods and the sub plot was landraces. There were differences in leaf shape and pod shape among the landraces. There were two main clusters of Indonesian landraces of bambara groundnut with 88.28% similarity. The first cluster was Cream, Brown Sumedang, Black Sumedang and Black Tasikmalaya, and the second cluster was Black Sukabumi, Brown Gresik, Black Madura, and Black Gresik. The result based on SSR marker with capillary electrophoresis indicated Black Gresik and Black Madura landraces were different from other Indonesian landraces. Cream Sumedang or Brown Sumedang from the first cluster and Black Gresik or Brown Gresik from the second cluster have the farthest distances for developing improved variety of bambara groundnut.

The Stability

The phenotypic analysis of new candidate varieties at multiple locations could provide information on the stability of their genotypes. We evaluated the stability of 11 maize hybrid candidates in five districts in East Java Province, Indonesia. Maize hybrids with high yield potential and early maturity traits derived from a diallel cross were planted in a randomized complete block design with two checks (Srikandi Kuning and BISI-2) as a single factor with four replicates. The observed traits were grain yield per hectare and harvest age. The effects of environment, genotype, and genotype × environment interaction on yield were highly significant (P < 0.01). KTM-1, KTM-2, KTM-4, KTM-5, and KTM-6 showed higher average grain yield per hectare than the checks (Srikandi Kuning = 8.49 ton ha−1 and BISI-2 = 7.32 ton ha−1) at five different locations. The average harvest age of 11 candidates was less than 100 days. KTM-4 and KTM-5 had production yields that were higher than the average yield of all genotypes in all environments (Yi > 7.78 tons ha−1) and were considered stable on the basis of three stability parameters, i.e., Finlay–Wilkinson, Eberhart–Russell, and additive main effect multiplicative interaction (AMMI). KTM-2 had the highest yield among all tested genotypes (9.33 ton ha−1) and was considered as stable on the basis of AMMI but not on the basis of Finlay–Wilkinson and Eberhart–Russell. KTM-1 performed well only in Pamekasan, whereas KTM-6 performed well only in Sampang. Thus, these two genotypes could be targeted for these specific locations.

Rice (Oryza sativa L.) is the most important crops commodity in Indonesia because it is the main staple for the people of Indonesia but currently, in Indonesia, the production of rice is still not maximal so it can not meet the demand of Indonesian people for national food needs. Therefore, it is necessary for rice plants that have high production and tolerant to various stresses. Plant breeding is one of the ways that can be done to increase the production of rice, one of which is the method of cross-recurring selection. Genetic diversity is a variation of characteristics that are inherited in the same species population. This study aims to obtain information about genetic diversity and agro-morphological characters of 50 genotypes rice derived from the recurrent selection. This research was conducted from August until December 2017 in Rawa Makmur Village, Bengkulu Province with the height of place from sea level ± 2 m. The study used a Completely Randomized Block Design (RAK) with 3 replications. The seeds used were 50 genotypes of rice from previous cross-selection results from Bugis/N-22 crossbreeds, Bugis/IR-7858-1, Sriwijaya/N-148, Sriwijaya/IR-7858-1. The results showed that the genetic diversity of rice is quite narrow to moderate, but there are some rice characters that have medium to high heritability value that was plant height, harvesting age, flowering age, the total number of tillers and panicle length, so that character can be used for the next generation rice selection. The genotypes produced by Bugis/IR-7858-1 crosses have panicle length, filled grain per panicle, and high grain weight/hill resulting in high yield potential.
