Inheritance Studies of Amylose Content, Yield and Grain Quality Characters in Different Rice Genotypes (Oryza sativa L.)

Aromatic rice constitutes a small but an important sub-group of rice. These are rated best in quality and fetch much higher price than high quality non-aromatic rice in international market. In spite of their importance, pace of improvement of this group of rice has been rather slow. Quality rice are characterized by not only aroma but also by several other traits like grain length and width, elongation after cooking, amylose content, gelatinization temperature etc. Grain quality in rice is very difficult to define with precision as preferences for quality vary from country to country and region to region in a country. The concept of quality varies according to the ways of preparations for which the grains are to be used. Although some of the quality characteristics desired by grower, miller and consumer may be the same, yet each may place different emphasis on various quality characteristics of rice. Physico-chemical characteristics and nutritional quality of 32 genotypes of aromatic rice (Oryza sativa L.) were analysed. A total of ten quality parameters related to grain were estimated and three nutritional estimation were also carried out using standard protocols. Maximum variations among the genotypes were observed for amylose content (AC), kernel length (KL), gel consistency (GC), carbohydrate content (CC) and protein content (PC). AC ranged from 2.97% to 20.60%, GC from 20.31 mm to 86.49 mm, CC from 29.83% to 82.18% and PC from 2.35% to 11.69%. In terms of nutritional quality analysis, Ja-Pnah (82.18%) followed by IC-465275 (81.55%) recorded the highest carbohydrate content. CT3-D-4 (11.69%) recorded the highest protein content whereas IC 137342 (0.99%) recorded the highest fat content. The promising genotypes identified in this study by emphasizing upon genotypes for various grain quality and nutritional traits can be utilized according to the choice of the breeder in further improvement of aromatic rice.

The Impact

Essential plant nutrient elements are generally applied to crops through soil to achieve more economic yields. Of the methods followed soil application is common and efficient for nutrients required in large quantities. However, under some situations crop responds better to foliar application along with blanket doses of fertilizers. Foliar application of urea phosphate (UP), an acidic nitrogen (N) and phosphate (P) nutrient fertilizers, along with blanket fertilizer doses can influence the yield as well as nutrient uptake and grain quality characteristics of the crop rice. A field experiment was conducted to study the impact of urea phosphate on yield, nutrient uptake and grain quality of rice (Oryza sativa L.) in acid Inceptisols of Odisha, India. Different treatments were thus framed to test the hypothesis as T1-control (no nutrient); T2- 50% recommended dose of fertilizer (RDF); T3 -75% RDF; T4 -100% RDF; T5 -50% RDF + twice foliar spray (FS) of 1% UP; T6 -50% RDF + twice FS of 2% UP; T7 -75% RDF + twice FS of 1% UP; T8 -75% RDF + twice FS of 2% UP; T9 -100% RDF + twice FS of 1% UP and T10 -100% RDF + twice FS of 2% UP. Growth parameters like plant height (107.60 cm), panicle length (25.72 cm) and number of effective tillers per hill (13.58) were found to be highest in the plots where twice FS of 2% UP along with 100% RDF was applied. The grain (4579.33 kg ha-1) and straw yield (5121.90 kg ha-1) of rice were also observed highest with T10 over T9, where 100% RDF + twice FS of 1% UP was applied. Uptake of nutrients like N (63.45 kg ha-1), P (18.36 kg ha-1 ) and K (96.85 kg ha-1) were found to be numerically higher in T10 where 100% RDF + twice FS of 2% UP was applied. The grain quality parameters of rice like protein content (R² = 0.624), alkali value (R² = 0.622) and amylose content (R² = 0.618) were significantly varied among the treatments.

Abstrak. Beras (Oryza sativa L.) merupakan salah satu tanaman pangan yang berfungsi sebagai tanaman pokok selain gandum dan jagung di Indonesia, dikarenakan mengandung nutrisi yang dibutuhkan tubuh seperti karbohidrat, protein, air dan lemak. Meningkatnya jumlah penduduk maka permintaan terhadap beras semakin meningkat. Permintaan tersebut sangat ditentukan oleh selera konsumen yang dipengaruhi oleh kualitas beras yaitu mutu fisik (ukuran dan bentuk butiran, rendemen dan pengapuran), mutu tanak (kadar amilosa dan suhu gelatinisasi) dan mutu rasa (tekstur dan aroma). Penelitian ini bertujuan untuk mengetahui kualitas beberapa galur padi mutan M4 hasil iradiasi sinar gamma. Penelitian ini dilaksanakan di Laboratorium Ilmu dan Teknologi Benih, Laboratorium Analisis Pangan dan Hasil Pertanian, Laboratorium Ilmu Nutrisi dan Teknologi Pakan dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala, serta Laboratorium Departemen Ilmu dan Teknologi Pangan Fakultas Teknologi Pertanian Institut Pertanian Bogor, yang berlangsung pada bulan April hingga Juli 2018. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) pola non faktorial dengan 3 ulangan. Perlakuan penelitian ini berupa galur (G) dengan 5 taraf, yaitu i-Snb (G0) kontrol, O-39e (G1), O-57d (G2), O-57e (G3) dan O-88j (G4). Parameter yang diamati yaitu sifat fisik beras (densitas kamba, derajat sosoh, dimensi beras rendemen beras giling, dan warna). Hasil penelitian menunjukkan bahwa galur mutan M4 berpengaruh sangat nyata terhadap kualitas sifat fisik rendemen beras giling dan warna nilai L (kecerahan). Rendemen beras giling terbaik galur O-39e (70,33%) dan warna nilai L (kecerahan) galur O-88j (117,90). Perlakuan terbaik secara kumulatif untuk sifat fisik beras yaitu pada i-Snb.. Physical Quality of Rice (Oryza sativa L. ) M4 Mutant Results of Gamma Ray IrradiationAbstract. Rice (Oryza sativa L.) is one of main food which the function is to be staple food beside wheat and corn in Indonesia because it contains nutrients such as carbohydrates, protein, water, and fat. Towards the increasing populations, the demand of rice is increasing as well. The demand is largerly depends on the consumer taste affected by the quality of rice which are physical quality (size and grain shape, rendemen, and calcification), cooked quality (amylose content and gelatinization temperature) and flavor quality (texture and smell). The purpose of this research was to investigate the quality of rice from several M4 mutant line resulting from gamma ray irradiation. This research was conducted at the Laboratory of Seed Science and Technology and Laboratory of Food and Agricultural Analysis, Faculty of Agriculture, Syiah Kuala University, Banda Aceh, from the month April to July 2018.
