Abstract

Planting pepper hybrid varieties offers an alternative strategy to meet needs of chili pepper in Indonesia. The aim of the experiment waere to evaluate and select nine pepper hybrids thus obtained peppers hybrid potential to be released as hybrid varieties of chili pepper. The experimental design used was Randomized Complete Block Design (RCBD) with one factor and three replications. Plant mateterials were nine pepper hybrid and five commercial hybrid of chili peppers. IPB CH3, IPB CH50 and IPB CH28 pepper hybrid  produced higher selection index value than comercial hybrid of chili pepper. The IPB IPB CH3, IPB CH50 and IPB CH28 pepper hybrid were potential to be released as hybrid varieties of chili pepper.

Abstract

Increased phenotypic diversity is needed to increase the economic value of Aglaonema. However, information on increasing phenotypic diversity of Aglaonema using gamma-ray irradiation has not been widely known. This study aimed to investigate the effect of gamma ray irradiation treatment to the performances of two varieties of Aglaonema. This research was arranged factorially using randomized group design (RKLT) of two factors consisting of 8 combinations of treatments that are 4 level of irradiation dose and 2 Aglaonema varieties. The results showed that the induction of gamma ray irradiation decreased the % viable of the plants, the number of leaves, leaf length, leaf width, and the % green color as well as increased the % blue on the leaves of Aglaonema Butterfly and Aglaonema Siam Aurora. The interaction between dose of irradiation and aglaonema varieties was obtained in the % red of leaf color. Both of Aglaonema varieties had a high radiosensitivity with LD50 values ranged of 16.70 - 17.14 Gy

Abstract

Penelitian ini bertujuan untuk membandingkan beberapa galur harapan cabai bersari bebas (OP) hasil pemuliaan Laboratorium Pemuliaan IPB dengan varietas cabai OP komersial dan mendapatkan galur yang memiliki karakter-karakter yang lebih unggul dibandingkan dengan varietas pembanding tersebut. Penelitian ini dilaksanakan pada bulan Juli 2010 sampai Januari 2011 di Kebun Percobaan Leuwikopo IPB. Percobaan dilaksanakan dengan menggunakan Rancangan Kelompok Lengkap Teracak dengan tiga belas perlakuan dan tiga ulangan sehingga seluruhnya terdapat 39 satuan percobaan. Galur yang diuji yaitu F6001004-5, F6002003-9, F6002005-4-76, F6002046-2, F6015002-8, F7002001-4, F7009002-1, F7009015-4, F7009019-1, dan F7015008-5, selanjutnya dibandingkan dengan tiga varietas cabai komersial yaitu varietas Trisula, Gelora, dan Tit Super. Peubah yang diamati meliputi tinggi tanaman, tinggi dikotomus, diameter batang, lebar kanopi, lebar daun, panjang daun, umur berbunga, bobot per buah, bobot buah layak pasar, dan bobot buah total. ?Berdasarkan peubah yang diamati menunjukkan bahwa galur F6002046-2, F6001004-5 dan F7009015-4 berpotensi sebagai calon varietas unggul.
