Abstract

Pea genotypes developed by national breeding program exhibit wide geographical adaptation. To identify the best high yielding and wide adaptive genotypes, fourteen garden pea genotypes (13 improved and commercial) were studied for their phenotypic traits at two locations (Horticulture Research Station, Dailekh and Agriculture Research Station, Dhankuta) during 2018–2019. Field experiments were conducted at randomized complete block design with three replications in both locations. Combined analysis over the locations revealed that genotypes had highly significant (p ≤ 0.01) effect on pod length, pod diameter, seed number/pod, pod weight and fresh pod yield. HRSDGP-11-18-1 produced the highest (12.5 t/ha) fresh pod yield, followed by HRSDGP-11-18-11 (12.3 t/ha) and the lowest (8.2 t/ha) fresh yield was recorded in HRSDGP-11-18-9. HRSDGP-11-18-1 and HRSDGP-11-18-11 had 25.0 and 23.0% higher yield advantage over Sikkim Local variety, respectively. Pod length, pod diameter and seed number/plot were significantly (p ≤ 0.01), and positively correlated with fresh pod yield, and selection of these traits aid for the improvement of yield in garden pea genotypes. HRSDGP-11-18-1 and HRSDGP-11-18-11 were found superior at both locations and can be recommended to evaluate them at on-farm condition for further verification.

多地点评估园豌豆基因型的豆荚特征和产量

国家育种计划开发的豌豆基因型具有广泛的地理适应性。为了确定最佳高产且适应性广的基因型，2018-2019年期间，在两个地点（Dailekh园艺研究站和Dhankuta农业研究站）对14个园艺豌豆基因型（13个改良型和商业型）的表型性状进行了研究。两个地点的田间试验均采用随机完全区组设计，三次重复。各地点的综合分析表明，基因型对豆荚长度、豆荚直径、种子数/荚、豆荚重和鲜荚产量的影响非常显著（p ≤ 0.01）。HRSDGP-11-18-1 的鲜荚产量最高（12.5 吨/公顷），其次是 HRSDGP-11-18-11（12.3 吨/公顷），而 HRSDGP-11-18-9 的鲜荚产量最低（8.2 吨/公顷）。与锡金本地品种相比，HRSDGP-11-18-1 和 HRSDGP-11-18-11 的产量优势分别为 25.0% 和 23.0%。荚长、荚直径和种子数/株与鲜荚产量呈显著正相关（p ≤ 0.01），选择这些性状有助于提高园豌豆基因型的产量。HRSDGP-11-18-1和HRSDGP-11-18-11在两个地点均表现优异，建议在农场条件下对其进行评估，以进一步验证。
