PENAMPILAN POPULASI F3 HASIL SELEKS

PENAMPILAN POPULASI F3 HASIL SELEKSI PEDIGREE DARI PERSILANGAN PADI MERAH KARAJUT DENGAN FATMAWATI



Abstrak


Penelitian ini bertujuan untuk mengetahui parameter populasi dan menghitung parameter genetik, karakter hasil dan komponen hasil serta melakukan seleksi individu pada populasi F3 berdasarkan sifat yang diinginkan khususnya warna beras, bobot 1000 butir, jumlah gabah per malai dan bobot gabah per rumpun. Penelitian telah dilaksanakan pada bulan Januari sampai Juni 2014 yang bertempat di UPT Farm Fakultas Pertanian Universitas Andalas Padang. Material genetik yang digunakan adalah benih F3 dari persilangan padi merah Karajut dengan Fatmawati (KF5, KF33 dan KF42) serta benih kedua tetuanya dengan metode Head to Row (Rumpun ke baris). Dari hasil penelitian didapatkan umur panen pada populasi F3 cenderung mendekati tetua Fatmawati yang tergolong genjah. Pada umumnya tingkat keragaman populasi lebih besar dari keragaman famili, akan tetapi kisarannya luas. Heritabilitas berkisar dari sedang sampai tinggi dan kemajuan genetik harapan (KGH) dengan intensitas seleksi 5% pada populasi F3 tergolong tinggi untuk semua karakter kecuali umur panen. Famili KF42 sudah didapatkan 100% warna berasnya merah sedangkan famili-famili lainnya masih mengalami segregasi. Individu-individu terpilih pada diferensial seleksi dengan intensitas 5% diharapkan dapat membawa sifat superior dari kedua tetuanya.

The APPEARANCE Of PEDIGREE SELECTION RESULT F3 POPULATIONS FROM CROSSES Of RED KARAJUT RICE With FATMAWATIAbstractThis research aims to know the parameters of the populations and genetic parameters, characters count results and component selection as well as do individual results on population based on the desired properties of the F3 in particular colors, weighs 1,000 grains of rice, the amount of grain per panicle and grain weight per clump. Research has been carried out in January to June 2014 at UPT Farm Faculty of agriculture Andalas University, Padang. The genetic material used is the seed of red rice mixture F3 Karajut and Fatmawati (KF5, KF33 and KF42) as well as the second seed tetuanya with the method of Head to Row (Clumps down the line). Of research results obtained age harvest on populations tend to approach elders Fatmawati F3 SL genjah. In general the level of diversity of a population larger than Araceae, but diversity is kisarannya wide. Heritabilitas range from moderate to high genetic progress and hope (KGH) and the intensity of selection 5% in populations belongs to the high F3 for all characters except the age harvest. The family had obtained 100% KF42 color red berasnya while the other family-family still had segregation. The individuals elected on differential selection with an intensity of 5% is expected to bring the superior properties of both tetuanya.Keywords: red rice, head to row, heritabilitas, differential selection.

APPEARANCE OF POPULATION F3 Pedigree SELECTION OF RED RICE cross KARAJUT Fatmawati Abstract This study aims to determine the parameters and calculate population genetic parameters, yield and yield components of character and conduct individual selection F3 populations based on the desired properties, especially the color of rice, 1000 grain weight, number of grains per panicle and grain weight per hill. The study was conducted from January to June 2014 were held at the Faculty of Agriculture Farm Unit Andalas University, Padang. Genetic material used is F3 seeds of red rice crosses Karajut with Fatmawati (KF5, KF33 and KF42) and second seed parent with methods Head to Row (clumps into line). From the results of harvesting on the F3 populations tend to approach the elders Fatmawati classified as early maturity. In general, the level of population diversity is greater than the diversity of families, but the range is wide. Heritability ranged from moderate to high expectations and genetic progress (KGH) with 5% selection intensity on the F3 population is high for all the characters except for harvesting. Family KF42 has obtained 100% color red rice while the families are still experiencing segregation. Individuals elected to the selection differential with intensity of 5% is expected to bring the superior properties of the two parents.
