19 May 2025 - The 𝐔𝐏𝐋𝐁 𝐂𝐫𝐨𝐩 𝐁𝐫𝐞𝐞𝐝𝐢𝐧𝐠 𝐚𝐧𝐝 𝐆𝐞𝐧𝐞𝐭𝐢𝐜 𝐑𝐞𝐬𝐨𝐮𝐫𝐜𝐞𝐬 (𝐂𝐁𝐆𝐑) 𝐋𝐚𝐛𝐨𝐫𝐚𝐭𝐨𝐫𝐲 is happy to welcome 𝐭𝐰𝐨 𝐁𝐒 𝐀𝐠𝐫𝐢𝐜𝐮𝐥𝐭𝐮𝐫𝐞 𝐬𝐭𝐮𝐝𝐞𝐧𝐭𝐬 majoring in 𝐂𝐫𝐨𝐩 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 (specializing in 𝐀𝐠𝐫𝐨𝐧𝐨𝐦𝐲) from Don Mariano Marcos Memorial State University - North La Union Campus — 𝐌𝐫. 𝐑𝐨𝐬𝐬𝐛𝐞𝐥𝐭 𝐎. 𝐀𝐦𝐚𝐝𝐞𝐨 and 𝐌𝐬. 𝐉𝐞𝐧𝐧𝐲 𝐅. 𝐃𝐚𝐨𝐚. They will be joining us as interns until 𝐉𝐮𝐧𝐞 𝟐𝟎𝟐𝟓.
They were accompanied on their first day by 𝐒𝐢𝐫 𝐈𝐬𝐨𝐧 𝐂𝐚𝐥𝐢𝐦𝐩𝐚𝐧𝐠, a 𝐟𝐚𝐜𝐮𝐥𝐭𝐲 𝐦𝐞𝐦𝐛𝐞𝐫 of the 𝘊𝘳𝘰𝘱 𝘚𝘤𝘪𝘦𝘯𝘤𝘦 𝘋𝘦𝘱𝘢𝘳𝘵𝘮𝘦𝘯𝘵 at the 𝘊𝘰𝘭𝘭𝘦𝘨𝘦 𝘰𝘧 𝘈𝘨𝘳𝘪𝘤𝘶𝘭𝘵𝘶𝘳𝘦, 𝘋𝘔𝘔𝘔𝘚𝘜 and an 𝘔𝘚 𝘗𝘭𝘢𝘯𝘵 𝘎𝘦𝘯𝘦𝘵𝘪𝘤 𝘙𝘦𝘴𝘰𝘶𝘳𝘤𝘦𝘴 𝘊𝘰𝘯𝘴𝘦𝘳𝘷𝘢𝘵𝘪𝘰𝘯 𝘢𝘯𝘥 𝘔𝘢𝘯𝘢𝘨𝘦𝘮𝘦𝘯𝘵 (𝘔𝘚 𝘗𝘎𝘙𝘊𝘔) 𝘨𝘳𝘢𝘥𝘶𝘢𝘵𝘦.
Their internship began with an 𝐨𝐫𝐢𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧 that covered the 𝘳𝘦𝘴𝘦𝘢𝘳𝘤𝘩 𝘢𝘤𝘵𝘪𝘷𝘪𝘵𝘪𝘦𝘴 of the 𝘊𝘉𝘎𝘙 𝘓𝘢𝘣, 𝘢 𝘭𝘦𝘤𝘵𝘶𝘳𝘦 𝘰𝘯 𝘎𝘰𝘰𝘥 𝘓𝘢𝘣𝘰𝘳𝘢𝘵𝘰𝘳𝘺 𝘗𝘳𝘢𝘤𝘵𝘪𝘤𝘦𝘴 (𝘎𝘓𝘗), and a 𝘨𝘶𝘪𝘥𝘦𝘥 𝘵𝘰𝘶𝘳 𝘰𝘧 𝘵𝘩𝘦 𝘭𝘢𝘣𝘰𝘳𝘢𝘵𝘰𝘳𝘺 𝘢𝘯𝘥 𝘰𝘳𝘤𝘩𝘢𝘳𝘥. The session was led by 𝘊𝘉𝘎𝘙 𝘪𝘯𝘵𝘦𝘳𝘯𝘴𝘩𝘪𝘱 𝘤𝘰𝘰𝘳𝘥𝘪𝘯𝘢𝘵𝘰𝘳𝘴 𝐌𝐚’𝐚𝐦 𝐃𝐚𝐧𝐢𝐞𝐥𝐥𝐞 𝐂𝐚𝐛𝐚𝐫𝐨𝐧𝐠 and 𝐒𝐢𝐫 𝐆𝐢𝐨 𝐉𝐞𝐧𝐞𝐥 𝐔𝐦𝐚𝐥𝐢, who provided insights and technical guidance throughout the day.
They also attended the 𝐔𝐏𝐋𝐁 𝐂𝐞𝐧𝐭𝐞𝐧𝐧𝐢𝐚𝐥 𝐏𝐫𝐨𝐟𝐞𝐬𝐬𝐢𝐨𝐧𝐚𝐥 𝐂𝐡𝐚𝐢𝐫 𝐋𝐞𝐜𝐭𝐮𝐫𝐞 by 𝐃𝐫. 𝐑𝐚𝐧𝐳𝐢𝐯𝐞𝐥𝐥𝐞 𝐌𝐚𝐫𝐢𝐚𝐧𝐧𝐞 𝐋.

07 April 2025 - The UPLB Crop Breeding and Genetic Resources Laboratory is pleased to welcome its two BS Biology interns from Southern Luzon State University Main Campus: 𝐒𝐞𝐚𝐧 𝐏𝐚𝐮𝐥 𝐑. 𝐁𝐮𝐠𝐡𝐚𝐰 and 𝐋𝐢𝐚𝐧 𝐀𝐧𝐠𝐞𝐥𝐨 𝐂. 𝐃𝐞𝐥𝐨𝐬 𝐑𝐞𝐲𝐞𝐬. They will be joining us and assisting with our work until May 2025.
Today, they had their 𝐨𝐫𝐢𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧, which included a lecture on 𝐆𝐨𝐨𝐝 𝐋𝐚𝐛𝐨𝐫𝐚𝐭𝐨𝐫𝐲 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞𝐬 (𝐆𝐋𝐏), as well as a 𝐭𝐨𝐮𝐫 of the 𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐨𝐫𝐲 and 𝐨𝐫𝐜𝐡𝐚𝐫𝐝. The activity was led by Assoc. Prof. Renerio Pelegrino Gentallan, with support from the CBGR lab internship coordinators, Ma’am Danielle Cabarong and Sir Gio Jenel Umali, who helped with the technical details and ensured everything went smoothly.
We are excited to have 𝐒𝐞𝐚𝐧 and 𝐋𝐢𝐚𝐧 on board and look forward to the contributions they will make during their time with us!

After careful examination of the Vitex trifolia complex in the Philippines, we propose reinstating V. elmeri Moldenke and delineating V. arvensis Gentallan, Sengun & M.B.Bartolome as a new endemic species predominantly found under cultivation.
This newly delineated species graced the volume cover of PhytoKeys.
The following are our key findings.
1. We do not have 𝘝𝘪𝘵𝘦𝘹 𝘯𝘦𝘨𝘶𝘯𝘥𝘰 s. str. in the Philippines.
2. We predominantly use 𝘝𝘪𝘵𝘦𝘹 𝘢𝘳𝘷𝘦𝘯𝘴𝘪𝘴 Gentallan, Sengun & M.B.Bartolome, a newly delineated endemic species in the Philippines.
3. We use all five species of the 𝘝𝘪𝘵𝘦𝘹 𝘵𝘳𝘪𝘧𝘰𝘭𝘪𝘢 complex as medicinal "lagundi", and the dichotomous key to identify these species is presented.
