Heritability Analysis of  Local Corn Cultivars from Kisar Island Southwest Maluku After Induced with Colchicine

In the plant breeding program, selection is one process which aimed to obtain some varieties with superior traits. Within this process, one of criteria that must be consider is the wide genetic diversity of the plant which was selected, and how these traits are inherited. The purpose of this research was to determine (1) the influence of cultivar differences and the colchicine concentration towards the growth and production of local corn cultivar from Kisar Island Maluku, (2) to determine the heritability of growth and production variables after induced with colchicine. Completely randomized block design was used in this research with factorial design that consist of two factors i.e corn cultivar and colchicine concentration. The research procedure starts from field and seed preparation, immersion of seed into the colchicine solution, transplantation of seed into the field, plant maintenance, and harvesting. The variable measured including growth and production variables of corn. The analysis of variance showed a significant effect of cultivar differences on all growth and production variables (p value > 0.05), while colchicine concentration only showed a significant effect toward the plant height and number of seed per ear. The heritability analysis result showed that all variables observed were in high category. The different corn cultivars have a significant effect on all the growth and production, while the colchicine concentration only affect the plant height and number of seed per ear, and the heritability were in high category. This research provides useful information to farmers how to use colchicine to trigger plant growth and production. It can be used as an information in selecting corn cultivars with high yield potential.

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.

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.

Tungro disease is one of the important diseases of rice because it has a high potential for causing damage. The use of varieties resistant to the tungro disease effectively prevent an explosion tungro disease. Testing of promising lines resistant to the tungro at several locations is a stage in the breeding program before a line is released as a new variety that has resistance to tungro disease, as well as having the potential for high yields and good adaptation at several locations. Six of tungro resistant promising line (OBSTG02-137, OBSTG02-124, OBSTG02154, OBSTG02-130, OBSTG02-56, dan OBSTG02-37) and four check varieties (Inpari 9 Elo, Tukad Unda, Ciherang, and IR64) were evaluated for their yield potential and adaptability at 16 locations in tungro endemic area during the dry season of 2011-2013. The experiment was arranged in a randomized block design with 3 replications. Each line were transplanted in 4 m x 5 m plot size with plant spacing 25 cm x 25 cm. Observation were made on yield, 50% flowering date, plant heights, panicle number per hill, number filled and unfilled spikelets per panicle, and weigh of 1000 grains in gram. The results showed that effect of genotype x location interaction was significantly different for all component observed. Based on the performance of grain yield and yield components obtained, four lines i.e. OBSTG02-137 (6.74 t/ha), OBSTG02-124 (6.20 t/ha), OBSTG02-154 (6.37 t/ha ), and OBSTG02-130 (5,92 t/ha) has a high yield with the support of filled grain number and weight of 1000 seeds is high. Based on the combined value of bi and the general average of yield, then line OBSTG02-137, OBSTG02-154, and OBSTG02-130 were suitable to adapt to all environments, OBSTG02-124 is adapted in an optimal environment, OBSTG02-56 and OBSTG02-37 were adapted to the less productive environment.
