Abstract

Characterization is the first stage in plant breeding that aims to reveal the morphological character and selection of the genotypes that adapt to low-altitude of area. To fulfill caisin consumption demands in Indonesia, extensification was needed from high altitude grounds which is the natural habitat of caisin to low-altitude. Randomize Complete Block Design (RCBD) is used and genotype as a single factor. 15 genotypes were used from collection of PKHT BRP 004, BRP 002, BRP 009, BRP 022, BRP 007, BRP 020, BRP 010, BRP 012, BRP 021, and those given the induction of mutations in BRP 004 R, BRP 002 R, BRP 009 R, BRP 003 R, and BRP 019 R. The data were analyzed by analysis of variance then Tukey test as the advanced test. BRP 010 genotype has the heaviest total harvest mass and harvest mass without the root, yet BRP 009 R genotype has the highest harvest index score which means it has the highest percentage of edible part. BRP 002 R, BRP 009 R, and BRP 019 R, are genotypes from the irradiation process that has color diversity. The result of analysis of variance showed that from 11 quantitative characters from 15 caisin genotypes, 3 characters was found not showing a true statistical difference, there are quantity of leaf, leaf width, and height ratio (NLP), and stalk width. BRP 022 Genotypes has the narrowest and the shortest leaf, the shortest leaf stalk, and the narrowest leaf diameter. BRP 002 has the highest plant height and Sri Tanjung genotype has the shortest plant height. BRP 010, BRP 004 R, BRP 002 R, BRP 019 R and BRP 009 R genotypes have potential to submitted for new varieties candidate that adaptive to low-altitude ground.

形态形态和能量测试结果15种Caisin (Brassica rapa L.Cv)。Caisin组)
鉴定是植物育种的第一步,旨在揭示植物的形态特征和选择适应低海拔地区的基因型。为了满足印尼对酪素的消费需求,需要从作为酪素自然栖息地的高海拔地区向低海拔地区扩展。采用随机完全区组设计(RCBD),基因型为单因素。从PKHT收集的brp004、brp002、brp009、brp022、brp007、brp020、brp010、brp012、brp021基因型,以及诱导brp004 R、brp002 R、brp009 R、brp003 R和brp019 R基因型中选取15个基因型,采用方差分析,并以Tukey检验为高级检验。brp010基因型的总收获质量和无根收获质量最重,而brp009 R基因型的收获指数得分最高,即可食用部分的百分比最高。brp002 R、brp009 R和brp019 R是辐照过程中产生的基因型,具有颜色多样性。方差分析结果表明,15个柴豆素基因型的11个数量性状中,有3个性状的叶片数量、叶宽高比(NLP)和茎宽不存在真正的统计差异。brp022基因型叶片最窄、最短,叶柄最短,叶径最窄。brp002株高最高,Sri Tanjung株高最低。BRP 010、BRP 004 R、BRP 002 R、BRP 019 R和BRP 009 R基因型具有候选低空适应品种的潜力。
