Key Cultivation Techniques for the Two-Line Hybrid Japonica Rice Wandao 48
To meet the demand of the high-quality japonica rice market, the Rice Research Institute of the Anhui Academy of Agricultural Sciences developed the high-quality two-line japonica hybrid combination Wandao 48 (also known as 70 You Shuang Jiu) by crossing 7001S with 2277. Through experimental demonstration and grain quality evaluation, it has shown high quality, high yield, and multi-resistance. 1 Characteristics and Traits: It belongs to the early-maturing late japonica type, with a whole growth period of 128 days (double-cropping late rice) to 140 days (single-cropping late rice). Plant height is 93 cm. Plant type is moderately compact. Leaf color is light green. Main stem has 15 to 17 leaves. Panicle is umbrella-shaped. Panicle length is 19.8 cm, with more than 110 total grains per panicle and a seed-setting rate of 85%. Grains are oval. Awnless. Hull is thin and light yellow. 1000-grain weight is 24 to 26 g. Strong photoperiod sensitivity. Requires above-medium fertility. Strong tillering ability and high productive tiller rate. Fast grain filling and good color retention at maturity. Relatively easy to thresh. Tolerant to low temperatures. According to artificial inoculation identification by the Plant Protection Institute of the Anhui Academy of Agricultural Sciences, it is moderately resistant to rice blast (grade 3) and bacterial leaf blight (grade 3). Brown rice rate 83.1%, milled rice rate 75.3%. Head rice rate 74.0%, grain length 5.3 mm, length-to-width ratio 1.9; chalky grain rate 7%, chalkiness degree 0.9%, transparency grade 1. Gelatinization temperature is low (grade 6.9), gel consistency is soft (80 mm), amylose content 18%, protein 9.3%. Good eating quality. Good grain elongation.

A Complete Analysis of the Key Points of High-Yield Cultivation Techniques for Two-Line Rice
Two-line rice has characteristics such as early and rapid growth in the early stage, smooth color transition in the middle stage, a long late-maturing period, tolerance to fertilizer and disease resistance, large panicles with many grains, relatively good grain quality, stable and high yield, and a more obvious yield-increasing advantage over three-line rice. Therefore, in recent years it has been promoted and applied over relatively large areas in various places. In practice, we earnestly implemented the "six improvements" measures for high-yield cultivation, gave play to the high-yield advantages of two-line rice, and achieved gratifying results. 1. Improve seedling-raising techniques and cultivate strong seedlings. According to the characteristic that two-line rice has little flexibility in seedling age, carry out classified seedling raising.

Two-line hybrid rice once again sets a world record
In 2013, the two-line hybrid Y Liangyou 900 reached a yield of 988.1 kg per mu in a 100-mu demonstration, once again setting the world record for the highest yield per unit area of hybrid rice over a relatively large area. The two-line hybrid Y Liangyou 900 reached a yield of 988.1 kg per mu in a 100-mu demonstration. This is the 12th Five-Year Plan undertaken by the Hunan Hybrid Rice Research Center
