摘要

评价了传统水稻品种为地区农民提供补助型和气候适应型高产作物。选定的水稻品种维持了该地区的粮食生产和安全。在**研究大学农业研究农场进行了一项试验,以评估选定的传统水稻品种的性能。采用随机区组设计,对来自**和其他邦的12个传统水稻品种(即Anjali、Hauska稻、Namsai Local稻、Gandhakasala 1号、Khamti Lahi、Sali、Ambing、Taker、Gandhakasala、Bora、Bihari Dhan和Jeerakasala)在2020年农作季进行了3个重复评价。各品种的生长和产量参数均有显著差异。分蘖数(11.83)和株高(62.97)分别由安平和南赛两种生境记录,而卡姆提高原的分蘖数(31.3)和株高(97.13 cm)最高。作物持续时间在Bora(90天),其次是Ambing和Namsai Local(100天),以及Jeerakasala(138天)、Gandhakasala 1、Sali和Gandhakasala(137天)。报告产量在Khamti Lahi (1.81 kg/ 6 m2,存续期130.67天),其次是Sali (1.74 kg,存续期100.67天)和Ambing (0.58 kg,存续期103.33天)。短生育期品种如Bora(生育期90天,产量1.10公斤/块)和Taker(生育期103天,产量1.23公斤/块)的产量为解决农民的作物问题引入了双产。相关分析表明,株高、营养期持续时间、有效分蘖数和每穗粒数是影响产量的主要因素,这些性状在选择方案中具有重要意义。该调查还建议进一步研究香稻或特色水稻品种的利用以及对传统品种进行遗传改良以提高其生产力的可能性。

Performance of selected traditional rice varieties under Namsai conditions of eastern Himalayas 
The traditional rice varieties were evaluated for furnishing complimentary and climate adopted high yield crop to the district farmer. The selected rice varieties maintain food production and security in the district. An experiment was conducted at the Agricultural Research Farm of the Arunachal University of Studies to assess the performance of selected traditional varieties of rice. Twelve traditional varieties of rice from Arunachal Pradesh as well as from other states (viz., Anjali, Hauska rice, Namsai Local, Gandhakasala 1, Khamti Lahi, Sali, Ambing, Taker, Gandhakasala, Bora, Bihari Dhan and Jeerakasala) were evaluated in a randomized block design with three replications during Kharif season of 2020. The varieties differed significantly for all the growth and yield parameters studied. The growth parameter of Tillers per hill (31.3) and plant height (97.13 cms) were observed in the Khamti Lahi, whereas the number of tillers (11.83) and the plant height (62.97 cms) were recorded by Ambing and Namsai Local respectively. The crop duration was seen in Bora (90 days), followed by Ambing and Namsai Local (100 days), and in Jeerakasala (138 days), Gandhakasala 1, Sali and Gandhakasala (137 days). The yield was reported in Khamti Lahi (1.81 kg/ 6 sq m and 130.67 days duration) followed by Sali (1.74 kg yield and 100.67 days duration) and Ambing (0.58 kg yield and 103.33 days duration). The yield of short duration variety like Bora (90 days duration and yield of 1.10 kg/ plot), and Taker (103 days duration and 1.23 kg yield) were reported to introduce double production for overcoming farmer’s crop problem. The correlation analysis showed that plant height, duration of vegetative phase, productive tillers and grains per panicle are the major factors contributing to yield, and these characters are important in a selection programme. The investigation also suggests further studies on utilization of scented or specialty rice varieties and possibility of genetic improvement of traditional varieties to enhance their productivity.
