Abstract

Abstract:

This study evaluated 70 glutinous rice varieties (lines) to identify high-quality, high-yield varieties suitable for cultivation in the Yangzhong region, based on comprehensive assessments of growth period, yield, and rice quality. The experiment was conducted in Yangzhong city, Jiangsu province, from 2021 to 2023, using a randomized block design with three replicates. The results showed the following: (1) The growth periods of the 70 glutinous rice varieties ranged from 137 to 159 days in 2021 and from 139 to 158 days in 2023. Based on the growth period, the varieties were classified into three categories: 17 early-maturing late-japonica types, 18 mid-maturing mid-japonica types, and 35 late-maturing mid-japonica types. (2) In 2021, yields ranged from 5.19 to 9.50 t hm^-2, and in 2023, yields ranged from 5.57 to 9.64 t hm^-2. Principal component analysis indicated that the number of grains per panicle and panicle number were the primary factors influencing yield traits. (3) In 2021, the brown rice rate ranged from 80.45% to 87.35%, and the milled rice rate from 59.86% to 75.87%. Twenty varieties met the first-class quality standard, while 16 met the second-class quality standard. In 2023, the brown rice rate ranged from 81.60% to 88.50%, and the milled rice rate from 65.07% to 75.59%. Fifteen varieties met the first-class quality standard, and 18 met the second-class quality standard. In 2021, protein content varied from 7.00% to 10.77%, and total starch content from 69.42% to 92.73%. In 2023, protein content ranged from 7.00% to 10.79%, and total starch content from 68.00% to 92.68%. Molecular marker analysis revealed that 35 rice varieties carried the badh2 gene. Based on the comprehensive analysis of growth period, yield, and quality, four high-yield and high-quality glutinous rice varieties (lines) suitable for cultivation in Yangzhong were selected: Yangruannuo 2, Sunuo 7132, Yangjingnuo 2, and Yandao 93207.
