Embodiment 1

[0015] 1) The high-yielding rice variety "Yanhui 559" was used as the recurrent parent (R), and the high-amylose rice variety-Guichao 13 (A), the storage-resistant rice variety-Yunhui 290 (B), and the iron-rich rice variety-IR164 (C) Provide parents with the anti-premature senescence rice variety Longjing 62 (D) for the target traits, and make crosses A / B and C / D to obtain hybrid F 1 Substituted by F 1 -AB, F 1 -CD said;

[0016] 2) Plant F 1 -AB, F 1 -CD seed, flowering stage for hybrid F 1 -AB / F 1 -CD, you have to repay F 1 Substitute, with F 1 -ABCD means planting F 1 -ABCD, harvest F 2 -ABCD;

[0017] 3) Planting 2) The resulting F 2 -ABCD, a group of 800 plants, at the maturity stage, select a single plant with strong rice stalks, green leaves and no premature aging to harvest the seeds and number them. Take a part of each seed to measure the amylose content and iron content, and screen to retain the iron content higher than 25mg·kg -1 And the amylose content...

Abstract

The invention discloses a breeding method of rice noodles dedicated special rice, and belongs to the technical field of special rice breeding. The method comprises the following steps: selecting rice variety which is large in popularization area in production, high in yield and good in quality as a recurrent parent, using the rice variety with premature senility resistance, endurable storage, high iron and high amylase as a target trait to provide the parent, hybridizing, multiple-crossing and back-crossing introducing and verifying and screening the target traits, breeding the special rice variety which has similar agronomic trait and yield with the recurrent parent, and has high amylose content, high iron, premature senility resistance, and endurable storage and is suitable for processing nutrient rice noodles.

Description

technical field [0001] The invention specifically relates to a method for breeding special rice for rice flour, and belongs to the technical field of special rice breeding. Background technique [0002] Ground rice has another name called rice noodle, is the traditional food that my country has long history, and it is liked by broad masses with soft and refreshing taste, instant. However, the processing of rice flour has certain requirements on raw materials. Not all rice is suitable for making rice flour. Edible rice mainly requires moderate amylose content, a high percentage of polished rice, crystal clear appearance, and good taste. Rice flour processing does not need to pay attention to appearance. , using varieties with relatively high amylose content as special rice for rice flour. About 1,000,000 tons of rice are used for rice flour processing in my country's mainland every year, accounting for about one-third of the total amount of rice used in food processing. Bre...
