Pre-breeding in Rice Development: Phenotypic-Genotypic Evaluation Associated with High Yield and Early Harvesting Traits

Phyton-International Journal of Experimental Botany 2024年第11期93卷 3073-3089页

The breeding process involves developing techniques to create cultivars that thrive in the ever-changing global climate,allowing for early harvesting and high *** study aimed to screen rice genotypes with early harvest-ing and high yield to develop new-generation *** study was conducted in aﬁeld experiment at the Department of Agronomy,Faculty of Agriculture,Universitas Gadjah Mada,Special Region of Yogyakarta,Indo-nesia,from December 2022 to April *** genotypes were laid out using an Augmented Randomized Com-plete Block Design(ARCBD)with three rows and six *** observations were macro and micro-climate,soil quality,and morphological traits of *** were analyzed using a Linear Mixed Model(LMM),correlation matrix,heatmap cluster,Principal Component Analysis(PCA),PCA-Biplot,Multiple Factor Analysis(MFA),and circular *** results provided information that the rice genotypes with the early harvesting genotypes were Inbrida M70D(95.01 days),Trisakti(100.98 days),and SR Super(104.76 days).Furthermore,the rice genotypes with the highest yields were Gamagora 2(49.82 g clump^(-1)),Gamagora 4(46.61 g clump^(-1)),Gamagora 7(37.26 g clump^(-1)),and Gamagora 10(29.84 g clump^(-1)).The genetic clustering based on Simple Sequence Repeat markers linked to earlyﬂowering genes indicates that SR Super and Inbrida M70D show the most distinct char-acteristics compared to other ***ﬁndings corroborate the morphological analysis,indicating that Inbrida M70D and SR Super are early harvesting genotypes,therefore they can be used this group of geno-types as cross-breeding material to obtain genotypes with early harvesting and high-yielding traits.
