Abstract

Abstract. The efforts to increase rice production at East Borneo apart from the improvement of cultivation systems also could be done by using superior variety. Hybridization of rice plants has been done between the female local variety Pandan Ungu and the male local variety Roti. The research toward F2 progeny to find out the segregation patterns of inheritance of the characters number of tillers, plant height, stem leaves color, and palea-lemma color has been done at the paddy field at Desa Sidomulyo, Kecamatan Anggana, Kabupaten Kutai Kartanegara since October 2016 until March 2017. The F2 identification method that was used is single plant selection methods, based on Standard Evaluation Systems (SES) for Rice. Suitability test between observed value and expected value used Chi-square test, and to see the characters segregation pattern ratio used Mendelian genetics analysis. The inheritance character of stem leaves color was managed by two pairs of genes followed segregation ratio 9:6:1 with the action epistatic genes with cumulative effect, the inheritance of palea-lemma character was managed by two pairs of genes followed Mendelian ratio 13:3 with the action epistatic dominant-recessive, while the characters plant height and number of tillers was managed by polygenes so the inheritance patterns was not following Mendelian ratio.

Abstract

Coconut water can increase the growth and yield of plants because itcontains plant growth regulator (PGR): auxin, cytokinin and gibberellin, vitamin, and mineral.The research was carried out to know: 1) the effect of coconut water concentrations on the growth and yield of mungbean and 2) concentration of coconut water that provide the best growth and yield of mungbean. The experiment was conducted during three months, from September until November 2017, located in Samarinda.The experiment was arranged in Completely Randomized Design (CRD) wasa single factor experiment, concentration of coconut water, consisted of four treatments: 0; 20; 40; and 60% of coconut water and each treatment was replicated six times. The data were analyzed by analysis of variance (anova) and continued by Least Significant Difference (LSD) test at significantlevel of 5%.Variables that observed were plant height, number of branches, number of pods, number of seeds, number of unfilled pods, weight of filled pods, andweight of seedsper plant.The result showed that the effect of coconut water concentrations was highly significant on plant height at 4, 6 weeks and at harvest time, number of pods, number of seeds, weight of filled pods, and weight of seeds per plant,howeveritwas significantly different on plant height at 2 weeks and number of branches, and it was no significantly different on number of unfilled pods. The best growth and yield of mungbean obtained by concentration 40% of coconut water.
