Judul ArtikelANALISIS JALUR DAN SELEKSI INDEKS BEBERAPA KARAKTER KOMPONEN HASIL TERHADAP HASIL PADI (Oryza sativa L.) POPULASI F4 HASIL PERSILANGAN CISOKAN DAN CIHERANG
AbstrakPenelitian ini bertujuan untuk: 1) mengetahui keragaman karakter komponen hasil dan hasil, 2) mengkaji pengaruh langsung dan tidak langsung antara beberapa karakter komponen hasil terhadap hasil melalui analisis jalur, 3) menyeleksi tanaman padi populasi F4 hasil persilangan Cisokan dan Ciherang berdasarkan seleksi indeks. Penelitian ini dilaksanakan di lahan sawah di Desa Pasir Kulon Kecamatan Karanglewas Kabupaten Banyumas pada bulan November 2016 sampai Juni 2017. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap Berblok (RBD) dengan rancangan perlakuan Augmented Design yang terdiri dari 3 blok. Variabel yang diamati yaitu kerapatan stomata kandungan klorofil saat pengisian bulir, kandungan klorofil sebelum panen, tinggi tanaman, jumlah anakan total, jumlah anakan produktif, waktu pengisian bulir, umur panen, panjang malai, jumlah gabah per malai, persentase gabah isi per malai, bobot 1000 biji, dan bobot gabah per rumpun. Hasil penelitian menunjukkan bahwa karakter komponen hasil dan hasil padi populasi F4 hasil persilangan Cisokan dan Ciherang beragam. Karakter komponen hasil yang memiliki pengaruh langsung yang nyata terhadap variabel hasil adalah kandungan klorofil sebelum panen, jumlah anakan produktif, waktu pengisian bulir, panjang malai, jumlah gabah per malai, dan persentase gabah isi per malai. Tanaman padi populasi F4 hasil persilangan Cisokan dan Ciherang yang dapat dilanjutkan untuk seleksi F5 adalah CSXCH-5-4-37, CSXCH-5-4-34, CSXCH-5-7-44, CSXCH-5-1-87, CSXCH-5-4-31, CSXCH-5-1-1, CSXCH-5-7-32, CSXCH-5-6-22, CSXCH-5-6-34, CSXCH-5-4-40, CSXCH-5-5-29, CSXCH-5-5-36, CSXCH-5-1-44, CSXCH-5-5-32, CSXCH-5-5-53, CSXCH-5-1-17, CSXCH-5-7-31, CSXCH-5-6-48, CSXCH-5-6-56, dan CSXCH-5-7-12.
Abstrak (Inggris)This research aims to: 1) know the diversity characters of yeild component and yeild, 2) Assessing the direct and indirect effects some characters of yeild component and yeild through path analysis, 3) select the rice crop of F4 population from Cisokan and Ciherang crossbreed based on index selection. This research has been conducted in paddy field at Pasir Kulon Village Karanglewas Subdistrict Banyumas Regency in November 2016 until June 2017. The experimental design used was a randomized complete block design (RBD) with an Augmented Design treatment design consisting of 3 blocks. The materials used are 417 genotype F4 of Cisokan and Ciherang crosses, and 3 check varieties (Cisokan, Ciherang, and Inpago Unsoed 1). The variables research were stomatal density, chlorophyll content during grain filling, chlorophyll content before harvest, plant height, number of total tillers, number of productive tillers, grain filling time, harvesting days, panicle length, number of grains per panicle, filled grain percentage per panicle, 1000 grain weight, and grain weight per clump. The results showed that the character of yield and yield components of F4 population of Cisokan and Ciherang crosses varied. Character of yield components that have a significant direct effect on yield chlorophyll content before harvest, number of productive tillers, grain filling time, panicle length, number of grains per panicle, and filled grain percentage per panicle. Rice crops of F4 populations of Cisokan and Ciherang crossbreed that can be continued for selection F5 are CSXCH-5-4-37, CSXCH-5-4-34, CSXCH-5-7-44, CSXCH-5-1-87, CSXCH-5-4-31, CSXCH-5-1-1, CSXCH-5-7-32, CSXCH-5-6-22, CSXCH-5-6-34, CSXCH-5-4-40, CSXCH-5- 5-29, CSXCH-5-1-44, CSXCH-5-5-32, CSXCH-5-5-53, CSXCH-5-1-17, CSXCH-5-7-31, CSXCH-5-6-48, CSXCH-5-6-56, and CSXCH-5-7-12.
